ios - 检测不在 UITextField 上的触摸(使键盘隐藏)

Question

这个问题在这里已经有了答案:





iOS - Dismiss keyboard when touching outside of UITextField

我有一些 UITextFields 可以打开键盘。

我的问题是，如何检测不在任何 UITextField 中的屏幕触摸

我需要的伪代码:

if(screen is touched)
   if(touched view is NOT a UITextField)
      [self.view endEditing:YES];

有没有简单的方法来实现这一点？或者在未触摸 UITextField 时隐藏键盘的另一种更简单的方法？

谢谢!

只需添加 UITapGestureRecognizer供您查看和使用[self.view endEditing:YES];

- (void)addTapGesutre {
    UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc]  initWithTarget:self
                                                                             action:@selector(handleTapGesture:)];
    tapGesture.numberOfTapsRequired = 1;
    [self.view addGestureRecognizer:tapGesture];
}

- (void)handleTapGesture:(UITapGestureRecognizer *)tap {
    if (tap.state == UIGestureRecognizerStateEnded) {
        [self keyboardDismiss];
    }
}

- (void)keyboardDismiss {
    [self.view endEditing:YES];
}
