B18－iOS9的适配相关

1、警告directory not found for option问题

      ld: warning: directory not found for option '-F/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator9.0.sdk/Developer/Library/Frameworks'

      出现原因是因为Xcode7将framworks位置改变了，目前还没有方法解决。

 

2、控制台输出error问题，（不影响程序运行）
         Sep 22 13:48:43  openBridge[2525] <Error>: CGContextSaveGState: invalid context 0x0. If you want to see the backtrace, please set CG_CONTEXT_SHOW_BACKTRACE environmental variable.
         Sep 22 13:48:43  openBridge[2525] <Error>: CGContextTranslateCTM: invalid context 0x0. If you want to see the backtrace, please set CG_CONTEXT_SHOW_BACKTRACE environmental variable.
         Sep 22 13:48:43  openBridge[2525] <Error>: CGContextRestoreGState: invalid context 0x0. If you want to see the backtrace, please set CG_CONTEXT_SHOW_BACKTRACE environmental variable.

         解决方法：info.plist内的View controller-based status bar appearance键值对，改为YES或者删掉即可。

4、iOS9限制http的访问解决方案

方案一：将要访问的域名设置为白名单

方案二：直接去除http限制

5、在iOS9中使用URL scheme

在iOS9中，如果使用URL scheme必须在"Info.plist"中将你要在外部调用的URL scheme列为白名单，否则不能使用。key叫做LSApplicationQueriesSchemes ，键值内容是

LSApplicationQueriesSchemes urlscheme urlscheme2 urlscheme3 urlscheme4

<key>LSApplicationQueriesSchemes</key>
<array>
      <string>weixin</string>
</array>
