three20 TTTableViewController + TTActionSheetController

2012-05-22T07:32:00Z

1. 首页要实现TTActionSheetControllerDelegate

@interface TSPublishViewController : TTTableViewController<TTActionSheetControllerDelegate>
{
CATETYPE _cateType;
}
@property(nonatomic,assign)CATETYPE cateType;

@end

2. 在init中声明URLMAP规则

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.tableViewStyle = UITableViewStyleGrouped;
[[TTNavigator navigator].URLMap from:@"tt://displayChoices"
toViewController:self selector:@selector(displayChoices:)];
}
return self;
}

3. 在DataSource中tableViewDidLoadModel添加url

[items addObject:
[TTTableTextItem itemWithText:post.catname URL:@"tt://displayChoices"]];

4. 实现在方法

- (UIViewController*)displayChoices:(NSDictionary*)query{
TTActionSheetController *controller = [[[TTActionSheetController alloc] initWithTitle:@"Choose" delegate:self] autorelease];
[controller addDestructiveButtonWithTitle:@"Sigin In & Post" URL:@"tt://safechoice"];
[controller addButtonWithTitle:@"Create & Post" URL:@"tt://photo-library"];
[controller addCancelButtonWithTitle:@"Cancel" URL:nil];
return controller;
}

- (BOOL)actionSheetController:(TTActionSheetController *)controller didDismissWithButtonIndex:(NSInteger)buttonIndex URL:(NSString *)URL {
TTDPRINT(@"buttonIndex: %d URL: %@", buttonIndex, URL);
if (URL && [URL caseInsensitiveCompare:@"tt://manual"] == NSOrderedSame) {
return NO;
}
return (nil != URL);
}

ios 设置背景图片

2012-05-22T06:03:00Z

1.uiscrollview 设置背景图片

// Setup the Scroll View
UIScrollView*tempScrollView=(UIScrollView*)self.view;
tempScrollView.contentSize=CGSizeMake(320,720);

// Set Stationary Background, so that while the user scroll the background is
// fixed.
UIImage*img =[UIImage imageNamed:@"bg-body.jpg"];
[tempScrollView setBackgroundColor:[UIColor colorWithPatternImage:img]];

2. uiview 设置背景图片

self.view.backgroundColor = [UIColor colorWithPatternImage: [UIImage imageNamed:@"1.jpg"] ];

3. 个要比较推荐下面几种

在uiview设置背景图片

UIImageView* bgview = [[UIImageView alloc]initWithImage:TTIMAGE(@"bundle://uiscrollviewbg1.jpg")];
bgview.frame = CGRectMake(0, 0, scrollView.frame.size.width, scrollView.frame.size.height);
[self addSubview:bgview];
[bgview release];

在uiscrollview设置背景图片

UIImageView* bgview = [[UIImageView alloc]initWithImage:TTIMAGE(@"bundle://uiscrollviewbg.png")];
bgview.frame = CGRectMake(0, -100, 320, 100);
[_scrollView addSubview:bgview];
[bgview release];

three20 为什么self.navigationController.view 是nil

原文：http://stackoverflow.com/questions/3715461/three20-navigation-by-openurlaction-self-navigationcontroller-is-nil-in-pushed

当viewDidLoad执行后才不为nil，如果过早调就有问题

three20 用more button 分页，自动加载更多行

2012-05-20T04:02:00Z

参考原文：http://code.coneybeare.net/three20-how-to-autoload-more-results-when-you

下面的我的代码

///////////////////////////////////////////////////////////////////////////////////////////////////
- (void)tableViewDidLoadModel:(UITableView*)tableView {

NSMutableArray* items = [[NSMutableArray alloc] init];
for (TSBazaarInfo* post in _searchFeedModel.posts) {

[items addObject:
[TSBazaarListItem itemWithTitle:post.title caption:[NSString stringWithFormat:@"%@ | %@ | Post by %@",post.area_name,[post.created formatRelativeTime],post.username]
text:post.content price:post.pricetext contentid:post.contentid imageURL:post.icon URL: [NSString stringWithFormat:@"tt://bazaar/getone/%d",post.contentid]]];
}

if(!([items count]%10))[items addObject:[TTTableMoreButton itemWithText:@"More"]];
self.items = items;
TT_RELEASE_SAFELY(items);
}

- (void)tableView:(UITableView*)tableView cell:(UITableViewCell*)cell willAppearAtIndexPath:(NSIndexPath*)indexPath {
[super tableView:tableView cell:cell willAppearAtIndexPath:indexPath];
if (indexPath.row == self.items.count-1 && [cell isKindOfClass:[TTTableMoreButtonCell class]]) {
TTTableMoreButton* moreLink = [(TTTableMoreButtonCell *)cell object];
moreLink.isLoading = YES;
[(TTTableMoreButtonCell *)cell setAnimating:YES];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
[self.model load:TTURLRequestCachePolicyDefault more:YES];

three20 URLMAP 对象传递方法

2012-05-20T03:58:00Z

原文是这样的：http://three20.info/article/2010-10-06-URL-Based-Navigation#nativeparams

[map from:@"tt://menu/(initWithMenu:)" toSharedViewController:[MenuController class]];

[map from:[Contact class] name:@"view" toURL:@"tt://contact/view/(uid)"];

两种方法：

@interface Contact : NSObject {

}

@property (nonatomic, retain) NSNumber* uid;
@property (nonatomic, retain) NSString* firstName;
@property (nonatomic, retain) NSString* lastName;

@end

Contact* aContact = [[Contact alloc]
initWithFirstName:@"Johnny" lastName:@"Appleseed" uid:1];
NSString* url = [aContact URLValueWithName:@"view"]

然后通过

TTOpenURL(url);

NSArray *arr = [...load up with data...];
[[TTNavigator navigator] openURLAction:[[TTURLAction actionWithURLPath:@"tt://restaurant/Chotchkie's"]
applyQuery:[NSDictionary dictionaryWithObject:arr forKey:@"arraydata"]]];

然后在tt://restaurant对应的controller 代码中写上

-(id) initWithName: (NSString*)name query:(NSDictionary*)query {
for (MyObject* item in [query objectForKey:@"arrayData"])
//... do something with item ...
}

// ...
}

CodeIgniter 结合phpcms模板功能

2012-05-18T03:09:00Z

用了CodeIgniter框架几个月，之前一直习惯用phpcms 来做网站底层框架，后来发现在CodeIgniter 更加适合小站点应用开发，但是他自带的view功能，并不强大了，相反很吃力。相比之下phpcms的view模板解析就强大多了，结合之前做的一个项目，特地将增强的代码copy出来。

在CodeIgniter libraries中增加 template_cache.php

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
/**

final class template_cache {

public $cache_path;
public function __construct()

$tplfile= APPPATH.'views'.DIRECTORY_SEPARATOR.$module.DIRECTORY_SEPARATOR.$template.'.php';

if (! file_exists ( $tplfile )) {
show_error($tplfile , 500 , 'Template does not exist(1)');
}

$content = @file_get_contents ( $tplfile );

$filepath = $this->cache_path.DIRECTORY_SEPARATOR.'caches_template'.DIRECTORY_SEPARATOR.$style.DIRECTORY_SEPARATOR.$module.DIRECTORY_SEPARATOR;

if(!is_dir($filepath)) {
mkdir($filepath, 0777, true);
}
$compiledtplfile = $filepath.$template.'.php';
$content = $this->template_parse($content);
$strlen = file_put_contents ( $compiledtplfile, $content );
chmod ( $compiledtplfile, 0777 );
return $strlen;
}

然后在global_helper中增加一个 template函数

if ( ! function_exists('template'))
{
/**
* 模板调用
*
* @param $module
* @param $template
* @param $istag
* @return unknown_type
*/
function template($module = 'expatree', $template = 'index', $style = 'expatree',$return_full_path=true) {
global $CI;
if(!isset($CI))$CI =& get_instance();
if(!$style) $style = 'default';
$CI->load->library('template_cache','template_cache');
$template_cache = $CI->template_cache;
//编译模板生成地址
$compiledtplfile = $template_cache->cache_path.DIRECTORY_SEPARATOR.'caches_template'.DIRECTORY_SEPARATOR.$style.DIRECTORY_SEPARATOR.$module.DIRECTORY_SEPARATOR.$template.EXT;
//视图文件
$tplfile= APPPATH.'views'.DIRECTORY_SEPARATOR.$module.DIRECTORY_SEPARATOR.$template.EXT;
if(file_exists($tplfile)) {
if(!file_exists($compiledtplfile) || (@filemtime($tplfile) > @filemtime($compiledtplfile))) {
$template_cache->template_compile($module, $template, $style);
}
} else {
//如果没有就调取默认风格模板
$compiledtplfile = $template_cache->cache_path.DIRECTORY_SEPARATOR.'caches_template'.DIRECTORY_SEPARATOR.'default'.DIRECTORY_SEPARATOR.$module.DIRECTORY_SEPARATOR.$template.EXT;
if(!file_exists($compiledtplfile) || (file_exists($tplfile) && filemtime($tplfile) > filemtime($compiledtplfile))) {
$template_cache->template_compile($module, $template, 'default');
} elseif (!file_exists($tplfile)) {
show_error($tplfile , 500 , 'Template does not exist(0)');
}
}

if($return_full_path)
return $compiledtplfile;
else
return 'caches_template'.DIRECTORY_SEPARATOR.$style.DIRECTORY_SEPARATOR.$module.DIRECTORY_SEPARATOR.$template;
}
}

然后在MY_Controller.php
增加一个方法

/**
* 自动模板调用
*
* @param $module
* @param $template
* @param $istag
* @return unknown_type
*/
protected function view($view_file,$page_data=false,$cache=false)
{
$view_file=$this->template($this->page_data['controller_name'].$this->page_data['module_name'],$view_file);

$this->load->view($view_file,$page_data);
}

这样基本上完成了，可以直接phpcms 模板语法了

three20 如何在UITableVIew 上面加一个可以滑动的广告条

2012-05-18T02:50:00Z

效果类似于这样

最近一直比较纠结如何做好一个app，前段时间开始学习three20， three20确定可以简化很多问题，上面类似的效果很多app上面都有用到过，如何做呢？我尝过多次，思路两种：

1. 上面一个ttscrollview+ ttpagecontrol,下面一个tttableview.但是你发会现上面一直是固定的，下面uitableview滚动上面的不动。

2. tttbaleview 中来处理，利用tableHeaderView中做，代码如下：

#import "TSHomeViewController.h"
#import "TSHomeDataSource.h"

@interface TSHomeViewController ()

@end

@implementation TSHomeViewController

- (void)dealloc {
_scrollView.delegate = nil;
_scrollView.dataSource = nil;
TT_RELEASE_SAFELY(_scrollView);
TT_RELEASE_SAFELY(_pageControl);
TT_RELEASE_SAFELY(_images);

[super dealloc];
}

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.title = @"Home";
NSString *imgPath = [NSString stringWithFormat:@"bundle://%@.png",self.title];
self.tabBarItem = [[[UITabBarItem alloc] initWithTitle:self.title image:TTIMAGE(imgPath) tag:0] autorelease];

NSString *text =@"http://v2.expatree.com/uploadfile/2012/0419/94bc8f2fbca0df76785a1cfbd0deb651.png,http://v2.expatree.com/images/api/lion.png";

_images =[[text componentsSeparatedByString:@","] retain];

self.tableViewStyle = UITableViewStyleGrouped;
self.variableHeightRows = YES;
}
return self;
}

///////////////////////////////////////////////////////////////////////////////////////////////////
- (void)createModel {

self.dataSource = [[[TSHomeDataSource alloc]
initWithSearchQuery:@"v2"] autorelease];}

- (void)loadView {
[super loadView];

self.tableView.tableHeaderView = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, self.tableView.frame.size.width, 80.0f)];

_scrollView = [[TTScrollView alloc] initWithFrame:CGRectMake(0,0, 320, 80 )];
_scrollView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleLeftMargin;
_scrollView.dataSource = self;
_scrollView.delegate = self;
_scrollView.backgroundColor = [UIColor whiteColor];
_scrollView.zoomEnabled = NO;
// [_scrollView zoomToFit];
[self.tableView.tableHeaderView addSubview:_scrollView];

_pageControl = [[TTPageControl alloc] initWithFrame:CGRectMake(0,80-20, 320, 20)];
_pageControl.autoresizingMask = UIViewAutoresizingFlexibleWidth;
_pageControl.backgroundColor = [UIColor clearColor];
_pageControl.currentPage = 0;
_pageControl.numberOfPages = [_images count];
[_pageControl addTarget:self action:@selector(changePage:) forControlEvents:UIControlEventValueChanged];
[self.tableView.tableHeaderView addSubview:_pageControl];

}

///////////////////////////////////////////////////////////////////////////////////////////////////
// TTScrollViewDataSource

- (NSInteger)numberOfPagesInScrollView:(TTScrollView*)scrollView {
return _images.count;
}

- (UIView*)scrollView:(TTScrollView*)scrollView pageAtIndex:(NSInteger)pageIndex {
TTView* pageView = nil;

pageView = [[[TTView alloc] init] autorelease];
pageView.backgroundColor = [UIColor redColor];
pageView.userInteractionEnabled = NO;
pageView.frame = CGRectMake(0,0, self.view.bounds.size.width, 80);
pageView.contentMode = UIViewContentModeLeft;
}

TTImageView *imgView = [[TTImageView alloc]initWithFrame:CGRectZero];
[[TTURLRequestQueue mainQueue] setMaxContentLength:0];
imgView.urlPath= [_images objectAtIndex:pageIndex];
imgView.autoresizesToImage = YES;
[pageView addSubview:imgView];
return [pageView autorelease];
}

- (CGSize)scrollView:(TTScrollView*)scrollView sizeOfPageAtIndex:(NSInteger)pageIndex {
return CGSizeMake(320, 80);
}

#pragma mark -
#pragma mark TTScrollViewDelegate

- (void)scrollView:(TTScrollView*)scrollView didMoveToPageAtIndex:(NSInteger)pageIndex {
_pageControl.currentPage = pageIndex;
}

#pragma mark -
#pragma mark UIViewController overrides
- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {

}

#pragma mark -
