xcode7,ios9 部分兼容设置

内容来源广大的互联网

神奇的苹果公司，再一次让程序员中枪。

一、xcode7 新建的项目,Foundation下默认所有http请求都被改为https请求.

HTTP+SSL/TLS+TCP = HTTPS

也就是说，服务需要提供https(TLS 1.2)的接口；

如果服务不改变，则客户端info.plist的根<dict>需加下面的键值；

简单信任所有http服务器
<key>NSAppTransportSecurity</key>
<dict>
    <!--Connect to anything (this is probably BAD)-->
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

或者严谨的

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSExceptionDomains</key>
  <dict>
    <key>yourserver.com</key>
    <dict>
      <!--Include to allow subdomains-->
      <key>NSIncludesSubdomains</key>
      <true/>
      <!--Include to allow insecure HTTP requests-->
      <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
      <true/>
      <!--Include to specify minimum TLS version-->
      <key>NSTemporaryExceptionMinimumTLSVersion</key>
      <string>TLSv1.1</string>
    </dict>
  </dict>
</dict>

二、xcode7 默认开启，bitcode（iwatch需要），则会导致部分第三方框架报错（比如友盟的错误）

youmeng/libMobClickLibrary.a(MobClick.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture armv7

这是要么更新库，要么可以在 build setting 中，搜索bitcode,并吧 enable bitcode 设置为 NO

三、iOS9安装企业证书打包的app

企业证书打包的app，安装到手机里面后第一次打开app。不会像以前提示，信任还是不信任该证书；

这是个时候需要iOS9 设置-》通用-》描述文件-》企业级应用 中信任对应的企业开发者。

四、iOS9 URL Schemes 

除了要在项目info URL Types中设置URL Schemes，还需要在info.plist里面增加可信任的调用app，否则回报如下错误

-canOpenURL: failed for URL: "weixin://app/wx9c8771d3c07dfd30/" - error: "This app is not allowed to query for scheme weixin"

-canOpenURL: failed for URL: "wtloginmqq2://qzapp" - error: "This app is not allowed to query for scheme wtloginmqq2"

info.plist加入(QQ跟微信的schemes)

<key>LSApplicationQueriesSchemes</key>

<array>
<string>mqqbrowser</string>
<string>mqq</string>
<string>mqqapi</string>
<string>mqqopensdkapiV2</string>
<string>weixin</string>
<string>wechat</string>
<string>tencent</string>
<string>QQ</string>
<string>wtloginmqq2</string>
<string>mqqopensdkapiV3</string>
<string>mqqopensdkapiV2</string>
<string>mqqwpa</string>
<string>mqqOpensdkSSoLogin</string>
<string>mqq</string>
<string>mqzoneopensdkapiV2</string>
<string>mqzoneopensdkapi19</string>
<string>mqzoneopensdkapi</string>
<string>mqzoneopensdk</string>
<string>mqzone</string>
<string>wtloginmqq2</string>
<string>mqqopensdkapiV3</string>
<string>mqqwpa</string>
<string>mqqopensdkapiV2</string>
<string>mqqOpensdkSSoLogin</string>
<string>openmobileqq</string>
</array>

五、iPad适配Slide Over 和 Split View

分屏应用最好把纯代码改为stroyboard
