If you are using empty template for your project them make sure that you are correctly adding your view to window in appdelegate file in function named applicationDidFinishLaunching. 如果您正在为项目使用空模板，请确保将正确的视图正确添加到名为applicationDidFinishLaunching的appdelegate文件中的窗口中。
It can also happen when you target for iphone and using xid file related to ipad or another way. 当您以iphone为目标并使用与ipad相关的xid文件或其他方式时，也会发生这种情况。
hope it will help you and sorry for my bad english 希望对您有帮助，对不起我的英语不好
