Question

我正在使用

override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
        self.view.endEditing(true)
    }

为了在用户点击某个地方时关闭键盘，但它不起作用。而且我没有任何错误

我的VC已经构建完毕：查看＆gt; <视觉效果视图＆gt;视图＆gt;滚动视图＆gt; uiButton （它覆盖屏幕并作为上一个VC的退出/后退按钮）＆gt;可设计视图（这是我的登录表单所在的位置）

Answer 1

在界面构建器中，在点击手势后拖动您希望它关闭键盘的视图上的tap gesture recognizer，或者您可以按代码添加手势：

-(void)viewDidLoad
{
    [super viewDidLoad];

    UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tappedOutside:)];
    gestureRecognizer.cancelsTouchesInView = NO; 
    [scrollView addGestureRecognizer:gestureRecognizer];
}

将IBAction添加到tap gesture recognizer，例如- (IBAction)tappedOutside:(id)sender;

在实施文件中添加：

-(IBAction)tappedOutside:(id)sender {
   [self.view endEditing:YES];
}

夫特：

var tap : UITapGestureRecognizer = UITapGestureRecognizer(target: self,action: "dismissKeyboard") 
self.view.addGestureRecognizer(tap) 

func dismissKeyboard() {
   self.view.endEditing(true) 
}

Answer 2

使用打开该键盘的textField 并尝试

textField.resignFirstResponder()

Answer 3

首先，将代理人添加到您的文字归档

yourtextfiled.delegate=self

其次，为您的UIScrollview和View

设置用户互动功能

 override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
            yourtextfiled.resignFirstResponder()
 }

Swift键盘不会被touchesBegan解雇
