1. nsunknownkeyexception

    Terminating app due to uncaught exception ‘NSUnknownKeyException‘, reason: ‘[<UIApplication 0x14e7b130> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key view.

　　解决方法：Main Interface  设置为空。 

　　好几个错误和Deployment Info 里面的设置有关

　　Device Orientation 选项，Requires full screen 这几个选项可以重新选择试试。

 2: ionic 在xcode下面编译时，需要在search Paths 中的header Serarch Paths 中增加下面路径：

　　"$(OBJROOT)/UninstalledProjucts/$(PLATFORM_NAME)/include"
