iOS 8.3鍵盤通知不起作用

Question

這是我寫的鍵盤通知的代碼。下面的代碼適用於iOS 8.1 SDK。但是keyboardWasShown：和keyboardWillBeHidden的通知：在iOS 8.3設備中沒有收到。與iOS 8.3 sdk問題？

- (void)registerForKeyboardNotifications { 

    [[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(keyboardWasShown:) 
               name:UIKeyboardWillShowNotification object:nil]; 

    [[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(keyboardWillBeHidden:) 
               name:UIKeyboardWillHideNotification object:nil]; 

} 

- (void)keyboardWasShown:(NSNotification*)aNotification { 
} 


- (void)keyboardWillBeHidden:(NSNotification*)aNotification{ 
} 

Answer 1

的問題是與鍵盤的iOS 8.3。從鍵盤設置中取消選中Predictive和Split鍵盤，通知正常工作。

Answer 2

檢查它在8.4和它工作正常只是檢查是否registerForKeyboardNotifications方法獲取調用或不
