Xcode7.0错误

昨天更新Xcode7.0之后,首先遇到了http请求的问题,百度了一下找到了解决方法,修改info.plist文件,info.plist-->Open As-->Souce Code  在</dict>之前添加

<dict>
  <key>NSAllowsArbitraryLoads</key>
  <true/>
</dict>

然后继续运行APP,发现在使用delegate获取网络请求结果的时候,没有办法直接addsubview ,或者[self removeFromSuperview];

报错:This application is modifying the autolayout engine from a background thread, which can lead to engine corruption and weird crashes.  This will cause an exception in a future release.

解决:把代码写到GCD中(使用主线程更新UI)

        dispatch_async(dispatch_get_main_queue(), ^{

            // UI

            [self removeFromSuperview];

        });
