问题描述

当我在模拟器上运行我的应用程序时运行良好，当我尝试使用设备无法正常工作时我会收到以下错误：

When i run my app on simulator it runs well, when i try with device doesn't work and i get these errors:

注意：我的代码中没有找到任何类的authView

NOTE: i didn't find any kind of class authView in my code

推荐答案

当出现问题时在xcode 4中有一些参考，因为我声明IBOutlet引用authView然后运行它工作！，然后我删除了IBOutlet d eclaration并运作良好

something went wrong when in xcode 4 with some reference , cause i declared IBOutlet that reference authView then run and it worked!, then i removed the IBOutlet declaration and worked well
