如何在iPhone，iOS 3.2或更高版本上获得键盘UIView

Answer 1

我添加了简单地使用此[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow) name:UIKeyboardWillShowNotification object:nil];

和

- (void)keyboardWillShow { [self performSelector:@selector(addHideKeyboardButtonToKeyboard) withObject:nil afterDelay:0]; }

当键盘出现时调用。
