iOS模拟器未显示应用

Question

I'm getting this outlet message in the debugger when I go to start my application: "2014-07-17 23:52:13.449 Journey[59668:60b] The app delegate must implement the window property if it wants to use a main storyboard file." But I'm not getting any errors or warnings? Please help.

确保在App Delegate头文件中包含以下代码行。

@property (strong, nonatomic) UIWindow *window;
