我想知道如何使键盘消失时,用户触摸以外的UITextField。


当前回答

Swift版本,这与其他元素(如UIButton或另一个UITextField)结合使用:

override func viewDidLoad() {
    super.viewDidLoad()

    let tapper = UITapGestureRecognizer(target: self, action:#selector(endEditing))
    tapper.cancelsTouchesInView = false
    view.addGestureRecognizer(tapper)
}

其他回答

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {

    if let touch = touches.first{
     view.endEditing(true)

     }
}

只是使用这段代码在您的.m文件,它将辞职的文本字段,当用户点击文本字段之外。

 -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
  [textfield resignFirstResponder];
 }

Swift版本,这与其他元素(如UIButton或另一个UITextField)结合使用:

override func viewDidLoad() {
    super.viewDidLoad()

    let tapper = UITapGestureRecognizer(target: self, action:#selector(endEditing))
    tapper.cancelsTouchesInView = false
    view.addGestureRecognizer(tapper)
}

看看这个,这是最简单的方法,

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
      [self.view endEditing:YES];// this will do the trick
}

Or

这个库将处理包括滚动条自动滚动,点击空间隐藏键盘等…

在我的新发展中,我以巴里为例。它工作得很好!但我不得不包括一个轻微的变化,要求解散键盘,只有文本字段被编辑。

所以,我在Barry的例子中加入了以下内容:

- (void) textFieldDidBeginEditing:(UITextField *)textField
{
    _textBeingEdited = textField;
}
-(void) textFieldDidEndEditing:(UITextField *)textField
{
    _textBeingEdited = nil;
}

同时,我修改了hideKeyboard方法如下:

- (IBAction)hideKeyboard:(id)sender
{
    // Just call resignFirstResponder on all UITextFields and UITextViews in this VC
    // Why? Because it works and checking which one was last active gets messy.
    //UITextField * tf = (UITextField *) sender;
    [_textBeingEdited resignFirstResponder];
}
