ios程序上传app store过程总结

2012-06-01T05:48:00Z

1 申请开发者帐号

2 申请APP ID

https://developer.apple.com/ios/manage/bundles/index.action

Description：San Zhang

Bundle Identifier (App ID Suffix): cn.a.appname

3 申请CSR

钥匙串访问－证书助理－从证书颁发机构求证书

填写注册开发账户时的邮箱和用户名，将CSR文件存储到磁盘。

4 申请发布证书

iOS provisioning portal-certificates-distribution-导入CSR文件－download－打开－在钥匙串访问中显示

5 申请distribution provisioning

iOS provisioning portal－provisioning－distribution－add new－submit－download－打开－自动关联

6 itunes connect中新增app，填写相关信息。

7 代码中新增Entitlements.plist文件

内容为：

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<dict>

<key>application-identifier</key>

<string>Z3VJF32UKJ.cn.a.appname</string>

<key>get-task-allow</key>

</dict>

</plist>

8 修改resource下的plist文件

Bundle identifier：cn.a.appname

9 配置xcode

项目－get info－configurations中新增distribution配置项。

Build选项－configuration选择为distribution－修改codesigning identify和any iphone os device为distribution证书。Targeted device family为iphone。

Target中－get info－做同上设置

10 clean，build and archive。

注意：文件目录层次不要太深。文件名长度进行控制。

11 打开xcode－organizer－archived applications－选择编译程序，validate－submit

html中不缓存swf的方法

2012-04-16T08:15:00Z

1 IIS中网站属性--HTTP头--启用内容过期

2 swf所在的html head中添加

参考：

swf 更新后，客户端不需要清空缓存即可查看最新版本

C# AutoCAD ActiveX 二次开发 -- CAD图层合并

2012-02-15T07:22:00Z

因使用AutoCAD版本为2004,2006版本以后才有.net开发包，因此采用ActiveX方式进行开发。

功能为：将几个CAD图层合并到其中一个上，并设置坐标，线和标记的颜色和字体。

CAD对象的层级为

AcadApplication -AcadDocument -AcadModelSpace AcadEntity

m_parentDirPath = ini.IniReadValue("road", "dir").Trim(); //读取
ini.IniWriteValue("road", "dir", "d:\\aa"); //写入

对应ini文件内容为：

[road]
dir=D:\lzx\data
