ios5开发-UITableView开启编辑功能

2012-05-04T03:39:00Z

该例子添加UITableView编辑功能

具体功能如下

功能很简单但很实用

@implementation AppDelegate

@synthesize window = _window;
@synthesize viewController = _viewController;
@synthesize navigationController=_navigationController;
@synthesize array=_array;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.array=[[NSMutableArray alloc] init];
    City *city1=[[City alloc] init];
    city1.name=@"KunShan";
    city1.description=@"Kunshan City,Jiangsu Province China.";
    City *city2=[[City alloc] init];
    city2.name=@"Shanghai";
    city2.description=@"Shanghai City, China.";
    City *city3=[[City alloc] init];
    city3.name=@"New York";
    city3.description=@"the largest city in New York State and in the United States; located in southeastern New York at the mouth of the Hudson river; a major financial and cultural center";
    City *city4=[[City alloc] init];
    city4.name=@"Tokyo";
    city4.description=@"the capital and largest city of Japan; the economic and cultural center of Japan";
    [self.array addObject:city1];
    [self.array addObject:city2];
    [self.array addObject:city3];
    [self.array addObject:city4];
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    self.viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
    self.navigationController=[[UINavigationController alloc] initWithRootViewController:self.viewController];

    self.window.rootViewController = self.navigationController;
    [self.window makeKeyAndVisible];
    return YES;
}

利用appDelegate定义一个nsmutablearrary数据源;应为appDelegate就是一个单例

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.title=@"City Guide";
    self.navigationItem.rightBarButtonItem=self.editButtonItem;
    self.tableView.allowsSelectionDuringEditing=YES;
    //self.navigationItem.rightBarButtonItem=[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:@selector(editTableView)];

    AppDelegate *app=(AppDelegate *)[[UIApplication sharedApplication] delegate];
    array=app.array;

    // Do any additional setup after loading the view, typically from a nib.

}

获取数据源

#pragma mark -uitableviewdelegate
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
    return 1;
}
-(NSInteger)tableView:(UITableView *)tv numberOfRowsInSection:(NSInteger)section{
    if ([tv isEditing]) {
        return [array count]+1;
    }else {
         return [array count];
    }

}
- (UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell=[tv dequeueReusableCellWithIdentifier:CellIdentifier];
    if (!cell) {
        cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
    }
    cell.accessoryType=UITableViewCellAccessoryDisclosureIndicator;
    // Configure the cell...
    if (indexPath.row<array.count) {


    City *thisCity=[array objectAtIndex:indexPath.row];
    cell.textLabel.text=thisCity.name;
    }
    else {
        cell.textLabel.text=@"Add City";
        cell.textLabel.textColor=[UIColor lightGrayColor];
        cell.editingAccessoryType=UITableViewCellAccessoryDetailDisclosureButton;


    }
    return cell;
}

-(void)tableView:(UITableView *)tv didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    if (indexPath.row< [array count] && !self.editing
        ) {
        //view city detail
        CityViewController *cityViewController=[[CityViewController alloc] initWithIndexPath:indexPath];
        [self.navigationController pushViewController:cityViewController animated:YES];
    }
    if (indexPath.row== [array count] && self.editing) {
        //add city
    }
    [tv deselectRowAtIndexPath:indexPath animated:YES];
}
-(void) tableView:(UITableView *)tv commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{
    if (editingStyle==UITableViewCellEditingStyleDelete) {
        [array removeObjectAtIndex:indexPath.row];
        [tv deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]withRowAnimation:UITableViewRowAnimationLeft];
    }
}
-(UITableViewCellEditingStyle )tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
    if (indexPath.row<[array count]) {
        return UITableViewCellEditingStyleDelete;
    }else {
        return UITableViewCellEditingStyleInsert;
    }

}
-(void)setEditing:(BOOL)editing animated:(BOOL)animated{
    if (editing!=self.editing) {
        [super setEditing:editing animated:animated];
        [tableView setEditing:editing animated:animated];
        NSMutableArray *indicies=[[NSMutableArray alloc] init];
        for (int i=0; i<[array count]; i++) {
            [indicies addObject:[NSIndexPath indexPathForRow:i inSection:0]];
        }
        NSArray *lastIndex=[NSArray arrayWithObject:[NSIndexPath indexPathForRow:array.count inSection:0]];
        if (editing==YES) {
            for (int i=0; i<array.count; i++) {
                UITableViewCell *cell=[tableView cellForRowAtIndexPath:[indicies objectAtIndex:i]];
                [cell setSelectionStyle:UITableViewCellSelectionStyleNone];
            }
            [tableView insertRowsAtIndexPaths:lastIndex withRowAnimation:UITableViewRowAnimationRight];


        }else {
            for (int i=0; i<array.count; i++) {
                UITableViewCell * cell=[tableView cellForRowAtIndexPath:[indicies objectAtIndex:i]];
                [cell setSelectionStyle:UITableViewCellSelectionStyleBlue];
            }
            [tableView deleteRowsAtIndexPaths:lastIndex withRowAnimation:UITableViewRowAnimationLeft];
        }
    }

IOS5开发-http get/post调用mvc4 webapi互操作(图片上传)

2012-04-06T02:22:00Z

目前最流行的跨平台交互是采用http协议通过JSON对象进行互操作。这种方式最简单，也很高效。webservice+xml的方式似乎已经过时。

下面是我做的一个例子

webapi的代码

public IEnumerable<Product> GetAllProducts()
        {
            Console.WriteLine(DateTime.Now.ToLongTimeString() + " : receive request.");
            return new List<Product>
            {
                new Product() { Id = 1, Name = "Gizmo 1", Price = 1.99M },
                new Product() { Id = 2, Name = "Gizmo 2", Price = 2.99M },
                new Product() { Id = 3, Name = "Gizmo 3", Price = 3.99M },
                new Product() { Id = 4, Name = "TShirt 3", Price = 5.99M },
                new Product() { Id = 5, Name = "SOFT TSHIRT", Price = 34.99M },
            };
        }

        public Product GetProductById(int id)
        {
            if (id < 1 || id > 3)
            {
                throw new HttpResponseException(System.Net.HttpStatusCode.NotFound);
            }
            return new Product()
            {
                Id = id,
                Name = "Gizmo " + id.ToString(),
                Price = id + 0.99M
            };
        }
        // POST /api/Products
        public Product Post(Product p)
        {
            Console.WriteLine(string.Format("submit Name:{0},Price:{1}",p.Name,p.Price));
            return p;
        }

// POST /api/Upload
        public string Post()
        {
            Console.WriteLine(DateTime.Now.ToLongTimeString() + " : receive upload request.");
            if (!Request.Content.IsMimeMultipartContent("form-data"))
           {
               throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);
            }
            MultipartFormDataStreamProvider streamProvider = new MultipartFormDataStreamProvider();

            // Read the MIME multipart content using the stream provider we just created.
            IEnumerable<HttpContent> bodyparts = Request.Content.ReadAsMultipartAsync(streamProvider).Result;

            // The submitter field is the entity with a Content-Disposition header field with a "name" parameter with value "submitter"
            //string submitter = "submitter";
            //if (!bodyparts.TryGetFormFieldValue("submitter", out submitter))
            //{
            //    submitter = "unknown";
            //}

            // Get a dictionary of local file names from stream provider.
            // The filename parameters provided in Content-Disposition header fields are the keys.
            // The local file names where the files are stored are the values.
            IDictionary<string, string> bodyPartFileNames = streamProvider.BodyPartFileNames;

            // Create response containing information about the stored files.
            return bodyPartFileNames.Select(kv =>
            {

                FileInfo fileinfo = new FileInfo(kv.Value);
                Console.WriteLine("receive file name:" + fileinfo.FullName + " Size:" + fileinfo.Length.ToString());
                return new FileResult
                {
                    FileName = kv.Key,
                   // LocalPath = fileinfo.FullName,
                   // LastModifiedTime = fileinfo.LastWriteTimeUtc,
                   // Length = fileinfo.Length,
                   // Submitter = submitter
                };

                //return FileResult;
            }).ToList()[0].FileName;

webapi 返回的IEnumerable<Product> 或 IQueryable<Product> 支持odata协议，odata协议功能很强大，查询很方便。可以关注。

第一个是通过http get/post获取服务端数据和更新服务端数据。

代码获取数据代码

- (IBAction)getAction:(id)sender {
    NSString *urlstring=self.urlTextField.text;
    NSURL *url=[NSURL URLWithString:urlstring];
    //NSData *jsondata=[[NSData alloc]initWithContentsOfURL:url];
    //NSLog(@"data:%@",[[NSString alloc] initWithData:jsondata encoding:NSUTF8StringEncoding]);
    NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:url];
    NSOperationQueue *queue=[[NSOperationQueue alloc] init];
    [NSURLConnection sendAsynchronousRequest:request queue:queue
                           completionHandler:^(NSURLResponse *respone,
                                               NSData *data,
                                               NSError *error)
     {
         if ([data length]>0 && error==nil) {
             NSString *jsonstring=[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
             //[self.respondTextView setText:jsonstring];
             NSLog(@"data:%@",jsonstring);
             //[self performSelectorOnMainThread:@selector(setRespondtext:)withObject:jsonstring waitUntilDone:YES modes:nil];
             [self performSelectorOnMainThread:@selector(setRespondtext:) withObject:data waitUntilDone:NO];
         }
     }
     ];

}

post数据代码如下

- (IBAction)postAction:(id)sender {
    NSString *urlstring=self.urlTextField.text;
    NSString *poststr=self.requestTextView.text;

    NSURL *url=[NSURL URLWithString:urlstring];
    NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:url];
    [request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setHTTPMethod:@"POST"];
    [request setHTTPBody:[poststr dataUsingEncoding:NSUTF8StringEncoding]];
    NSOperationQueue *queue=[[NSOperationQueue alloc] init];
    [NSURLConnection sendAsynchronousRequest:request queue:queue
                           completionHandler:^(NSURLResponse *respone,
                                               NSData *data,
                                               NSError *error)
     {
         if ([data length]>0 && error==nil) {
             NSString *jsonstring=[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
             //[self.respondTextView setText:jsonstring];
             NSLog(@"data:%@",jsonstring);
             //[self performSelectorOnMainThread:@selector(setRespondtext:)withObject:jsonstring waitUntilDone:YES modes:nil];
             [self performSelectorOnMainThread:@selector(setRespondtext:) withObject:data waitUntilDone:NO];
         }
     }
     ];

}

解析获取的JSON字符串

-(void) setRespondtext:(NSData *)data{
    NSString *text=[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    id jsonObject=[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];
    if (jsonObject !=nil) {
        NSLog(@"Successfully deserialized...");
        if ([jsonObject isKindOfClass:[NSDictionary class]]) {
            NSDictionary *deserializedDic=(NSDictionary *)jsonObject;
            NSLog(@"Dersialized Json dictionary =%@",deserializedDic);
        }
        else if([jsonObject isKindOfClass:[NSArray class]]){
            NSArray *deserializedArray=(NSArray *)jsonObject;
            NSLog(@"Derialized json array = %@",deserializedArray);
            for (NSDictionary *item in deserializedArray) {
                NSLog(@"Id : %@ Name: %@ Price : %@",[item objectForKey:@"Id"],[item objectForKey:@"Name"],[item objectForKey:@"Price"]);
            }
        }else{

        }
    }


    [self.respondTextView setText:text];

}

图片上传的代码

- (IBAction)uploadAction:(id)sender {
    NSString *urlstring=self.urlTextField.text;
    //NSString *poststr=@"";
    NSData *imgData=UIImageJPEGRepresentation(self.previewImageView.image, 0.9f);

    NSString *boundary = @"0xKhTmLbOuNdArY";
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary, nil];

    NSURL *url=[NSURL URLWithString:urlstring];
    NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:url];
    [request addValue:contentType forHTTPHeaderField:@"Content-Type"];
    [request setHTTPMethod:@"POST"];
    NSMutableData *body = [NSMutableData data];
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"iphonefile.jpg\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[NSData dataWithData:imgData]];
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];

    [request setHTTPBody:body];
    NSOperationQueue *queue=[[NSOperationQueue alloc] init];
    [NSURLConnection sendAsynchronousRequest:request queue:queue
                           completionHandler:^(NSURLResponse *respone,
                                               NSData *data,
                                               NSError *error)
     {
         if ([data length]>0 && error==nil) {
             NSString *jsonstring=[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
             //[self.respondTextView setText:jsonstring];
             NSLog(@"data:%@",jsonstring);
             //[self performSelectorOnMainThread:@selector(setRespondtext:)withObject:jsonstring waitUntilDone:YES modes:nil];
             //[self performSelectorOnMainThread:@selector(setRespondtext:) withObject:data waitUntilDone:NO];
         }
     }
     ];

}

我感觉使用ios sdk自带的NSMutableURLRequest,NSURLConnection, NSJSONSerialization,也非常方便，似乎没有必要去使用第三方的类库。

Convert an object into Json using SBJson or other JSON library

2012-04-04T04:54:00Z

Using SBJson, to convert a object to JSON string, you have to override the proxyForJson method. Like the following,

The .h file,

@interface MyCustomObject : NSObject {
    NSString *receiverFirstName;
    NSString *receiverMiddleInitial;
    NSString *receiverLastName;
    NSString *receiverLastName2;
}
@property (nonatomic, retain) NSString *receiverFirstName;
@property (nonatomic, retain) NSString *receiverMiddleInitial;
@property (nonatomic, retain) NSString *receiverLastName;
@property (nonatomic, retain) NSString *receiverLastName2;

- (id) proxyForJson;
- (int) parseResponse :(NSDictionary *) receivedObjects;
}

In the implementation file,

    - (id) proxyForJson {

        return [NSDictionary dictionaryWithObjectsAndKeys:
            receiverFirstName, @"ReceiverFirstName",
            receiverMiddleInitial, @"ReceiverMiddleInitial",
            receiverLastName, @"ReceiverLastName",
            receiverLastName2, @"ReceiverLastName2",
            nil ];
    }

And to get the object from the JSON string you have to write a parseResponse method like this,

- (int) parseResponse :(NSDictionary *) receivedObjects {
    self.receiverFirstName = (NSString *) [receivedObjects objectForKey:@"ReceiverFirstName"];
    self.receiverLastName = (NSString *) [receivedObjects objectForKey:@"ReceiverLastName"];

    /* middleInitial and lastname2 are not required field. So server may return null value which
     eventually JSON parser return NSNull. Which is unrecognizable by most of the UI and functions.
     So, convert it to empty string. */ 
    NSString *middleName = (NSString *) [receivedObjects objectForKey:@"ReceiverMiddleInitial"];
    if ((NSNull *) middleName == [NSNull null]) {
        self.receiverMiddleInitial = @"";
    } else {
        self.receiverMiddleInitial = middleName;
    }

    NSString *lastName2 = (NSString *) [receivedObjects objectForKey:@"ReceiverLastName2"];
    if ((NSNull *) lastName2 == [NSNull null]) {
        self.receiverLastName2 = @"";
    } else {
        self.receiverLastName2 = lastName2;
    }

    return 0;
}

一种自动的将自定义类序列化为JSON的方法

2012-04-01T22:41:00Z

【摘要】最近因为项目需求，需要将一些自定义的类序列化为JSON，网上有很多好用的第三方序列化工具，但都只能自动序列化一些基本类型，如NSNumber,NSString与NSDictionary这种，没有一种第三方工具提供直接将自定义类序列化的方法（至少据我所知：），而对于这种序列化自定义的类的需求，网上能查到的方法只有将自定义的类手动的转存为一个NSDictionary，然后再使用第三方工具来序列化。例如对于一个类Foo,有如下定义：?1234567891011121314151617181920212223242526272829303132333435363738394041@interface http://www.cnblogs.com/neozhu/archive/2012/04/02/2429556.html

IOS5开发-UIScrollView添加单击事件的方法

2012-03-30T06:28:00Z

UIScrollView在开发中是一个非常常用的控件，UIScrollView具有水平、垂直滚动和缩放效果。但是尽然没有响应单击事件这个事件。而这个事件在日常的交互中是非常需要的。比如当用于单击或轻触图片的某个位置时，给于一些交互性提示。

下面我将用例子说明一下如何给UIScrollView添加一个单击的响应。

代码如下：

添加一个自定义的UIScrollView，命名：UITouchScrollView

UITouchScrollView.h代码如下

#import <Foundation/Foundation.h>

@protocol UIScrollViewTouchesDelegate
-(void)scrollViewTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event whichView:(id)scrollView;
@end

@interface UITouchScrollView : UIScrollView

@property(nonatomic,assign) id<UIScrollViewTouchesDelegate> touchesdelegate;

@end

如果要想把单击事件传递出来，那么必须新建一个@Protocol UIScrollViewTouchesDelegate,用于响应并且对事件做出回调。这里说一下IOS的事件委托（Event Delegate）相对C#的事件委托还是不一样的，似乎实现起来没有C#方便。这里就不多说了。

UITouchScrollView.m代码如下

#import "UITouchScrollView.h"

@implementation UITouchScrollView
@synthesize touchesdelegate=_touchesdelegate;
- (void) touchesEnded: (NSSet *) touches withEvent: (UIEvent *) event {

    if (!self.dragging) {
        //run at ios5 ,no effect;
        [self.nextResponder touchesEnded: touches withEvent:event];
        if (_touchesdelegate!=nil) {

                    [_touchesdelegate scrollViewTouchesEnded:touches withEvent:event whichView:self];
                    }
        NSLog(@"UITouchScrollView nextResponder touchesEnded");
    }
    [super touchesEnded: touches withEvent: event];

}
@end

以上代码只是调用一下自定义的Delegate的方法。但是这里注意一下

[self.nextResponder touchesEnded:touches withEvent:event];这句话的意思是将UIScrollView上的单击事件往下传递，传递到它的父UIView。这样如果父UIView上实现了touchesEnded这个方法，也会响应到。但是这样的写法经过测试在IOS5.0以前的版本可以。但IOS5以后的（包括5）这不能往下传递，这里我也不知道为什么。希望有知道的朋友说一下。

ViewContrller.m代码如下

#pragma mark -

#pragma mark touches event
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
    NSLog(@"view touch began");
}
-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
    NSLog(@"view touch ended");
}
-(void)scrollViewTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event whichView:(id)scrollView{
    NSLog(@"scrollView  touch ended");

}

功能完成，记得在ViewController.h上加上UIScrollViewTouchesDelegate协议。

另外在说明一下。本来我想用UITapGestureRecognizer来实现的，但是直接引发异常。不明白为什么UITapGestureRecognizer不能注册在UIScrollViews上。

//self.tapGestureRecoginzer=[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTaps:)];

    //self.tapGestureRecoginzer.numberOfTapsRequired=1;
    //self.tapGestureRecoginzer.numberOfTouchesRequired=2;
    //[self.view addGestureRecognizer:self.tapGestureRecoginzer];

#pragma  mark -
#pragma mark handle taps event
-(void)handleTaps:(UITapGestureRecognizer *)sender{
    NSUInteger touchCounter=0;
    for (touchCounter=0; sender.numberOfTapsRequired; touchCounter++) {
        CGPoint touchPoint=[sender locationOfTouch:touchCounter inView:sender.view];

        NSLog(@"touch: %i: %@",touchCounter+1,NSStringFromCGPoint(touchPoint));
    }
}

2012-03-18T12:44:00Z

插上上网卡以后自动加载一个光盘映像

运行里面的程序把该装的都装了就可以了至于那个系统自带的拨号程序完全是废柴

打开网络设置创建一个新服务

下拉菜单选择HUAWEIMobile Modem 创建

高级厂商下拉选其他型号选哪个问题都不大好

XCode4.2.1 使用NavigationController实现View切换

XCode4.2.1 使用NavigationController实现View切换

现在网上有很多关于NavigationController实现页面之间导航，但是大部分都是老版本的实现方式，基于Window base application 模板实现，但新版本XCode 4.2.1没有这个模板，对于新手就算拿到源代码也不知道如何下手。

老版本实现的NavigationController项目源代码

但是新版的没有这个模板比如Single view application的项目直接生存ViewController不带Window和 mainWindow.xib文件

修改AppDelegate.m文件

加入代码后显示的界面就会出现导航栏了

如果要设置导航栏标题的内容，只需修改ViewController.m,你第一个载入的rootViewController

运行的效果

第二view上面导航按钮返回上一个view的功能不需要使用代码实现，当然写代码也可以，参考代码如下

希望对刚刚学习iphone开发的有所帮助，我也是刚刚开始学习。一起学习一起进步。

[self presentModalViewController:control animated:YES];
[control release];
描述：通过事件进行跳转
[self dismissModalViewControllerAnimated:YES];
描述：通过事件进行返回。
2.[self.navigationController pushViewController:subTableViewController animated:YES];
描述：通过 NSNavigationBar 进行跳转
[self.navigationController popViewControllerAnimated:YES];

SQL 2008 r2 安装提示 visual studio 2008 版本错误解决方法

2012-01-30T00:55:00Z

HKLM\SOFTWARE\Wow6432Node\Microsoft\DevDiv\VS\Servicing\9.0\IDE\1033

In that key I noticed the suspicious values:

"SP"=dword:00000000 "SPIndex"=dword:00000000 "SPName"="RTM"

Without quitting the SQL server installer validaton screen, I changed these values to what you see below, crossed my fingers and rerun the installer validation, which passed!

"SP"=dword:00000001 "SPIndex"=dword:00000001 "SPName"="SP1"
