我想知道如何使键盘消失时,用户触摸以外的UITextField。


当前回答

设置文本字段委托视图didload: 重载函数viewDidLoad() { super.viewDidLoad () self. usertext .delegate = self } 添加此函数: func textFieldShouldReturn(userText: UITextField! { userText.resignFirstResponder () 返回true; }

其他回答

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

如果视图被嵌入到UIScrollView中,那么你可以使用以下方法:

tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag;
tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeInteractive;

前者会在表格视图滚动时将键盘动画化,后者会像股票消息应用程序一样隐藏键盘。

注意,这些都可以在iOS 7.0或更高版本上使用。

斯威夫特4 oneliner

view.addGestureRecognizer(UITapGestureRecognizer(target: view, action: #selector(UIView.endEditing(_:))))

这里有很多关于使用UITapGestureRecognizer的很好的答案——所有这些都打破了UITextField的clear (X)按钮。解决方案是通过它的委托来抑制手势识别器:

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
    BOOL touchViewIsButton = [touch.view isKindOfClass:[UIButton class]];
    BOOL touchSuperviewIsTextField = [[touch.view superview] isKindOfClass:[UITextField class]];
    return !(touchViewIsButton && touchSuperviewIsTextField);
}

这不是最可靠的解决方案,但对我来说很管用。

如果我得到你的权利,你想辞职键盘狡猾敲在文本字段之外,但你没有你的文本字段的引用。

试试这个;

Take global textField, lets call it reftextField Now in textFieldDidBeginEditing set referenced text field to - (void) textFieldDidBeginEditing:(UITextField *)textField{ reftextField = textField; } Now you can happily use on any button clock, (adding a transparent button on begin editing recomended) - (void)dismissKeyboard { [reftextField resignFirstResponder]; } Or for resigning done button try this. //for resigning on done button - (BOOL) textFieldShouldReturn:(UITextField *)textField{ [textField resignFirstResponder]; return YES; }
