我的应用程序有许多视图，有很多表单。当我尝试使用我的应用程序时，单击并滚动每个位置。当我尝试单击文本字段或文本视图时，我发现我的应用程序崩溃了EXC_BAD_ACCESS。我在不同的崩溃中遇到以下错误：
1. `-[__NSDictionaryM keyboardDidShow:]: unrecognized selector sent to instance 0x16589960
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSDictionaryM keyboardDidShow:]: unrecognized selector sent to instance 0x16589960'`
