Application windows are expected to have a root view controller at the end of application launch

[pccai]

升级xcode7后运行的时候就提示Application windows are expected to have a root view controller at the end of application launch. 在ios9+以上真机run导致闪退。

解决办法：在didFinishLaunchingWithOptions 函数后面加入 [self.window makeKeyAndVisible]; 即可

• (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

  。。。。。。

  [self.window makeKeyAndVisible];
  return YES;
  }

你是先在xcode6跑了一次，又在xcode7跑了一次？ 你说一启动就崩溃，我一直也都是9.3.2真机调试啊。
