当点击位于子视图中的uitextfield外部时，iOS是否隐藏键盘？

我是新来的（我也是阿根廷人，很抱歉我的基础英语），我真的不知道该怎么解决这个问题。我有一个视图，其中包含一个用于滚动视图的

UIScrollView

，在其中我有一个子视图，其中包含许多

UITextField

。关键是当我在

UITextField

之外触摸时隐藏键盘，但我认为触摸事件没有触发（我不知道为什么，也许你可以帮我）。我也是iOS的新手，但我正在学习！谢谢

编辑：首先，感谢大家的回答！对于所有说要禁用usar交互的人来说，它适用于UITextFields，但现在我无法与UITable的内部de子视图交互！有什么帮助吗？

试试这个

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
        [self.view endEditing:YES];    
    }

还是这个

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    for (UIView * youtxtfl in self.view.subviews){
        if ([youtxtfl isKindOfClass:[UITextField class]] && [youtxtfl isFirstResponder]) {
            [youtxtfl resignFirstResponder];
        }
    }
}

滚动视图将截取手势识别器，您需要在单击文本字段后禁用视图上的用户交互

你可以通过

scrollView.userInteractionEnabled = NO;

希望这对您有所帮助：）

XIB文件中有属性，请查看下面的屏幕截图

下一个解决方案是UITextView，但您可以为UITextField修改它

1） Add Keyboard将在包含字段的视图控制器中显示事件处理程序，并保存对字段的引用

/**
Listen keyboard events

:param: animated the animation flag
*/
override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)
    initNavigation()
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillShow:", name: UIKeyboardWillShowNotification, object: nil)
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillHide:", name: UIKeyboardWillHideNotification, object: nil)
}

/**
Remove self as keyboard listener

:param: animated the animation flag
*/
override func viewWillDisappear(animated: Bool) {
    NSNotificationCenter.defaultCenter().removeObserver(self, name: UIKeyboardWillShowNotification, object: nil)
    NSNotificationCenter.defaultCenter().removeObserver(self, name: UIKeyboardWillHideNotification, object: nil)
}

/**
Save reference to focused textView

:param: sender the sender
*/
func keyboardWillShow(sender: AnyObject){
    if self.searchTextField?.isFirstResponder() ?? false {
        KeyboardDismissingUIViewTarget = self.searchTextField
    }
}

/**
Clean KeyboardDismissingUIViewTarget

:param: sender the sender
*/
func keyboardWillHide(sender: AnyObject){
    KeyboardDismissingUIViewTarget = nil
}

2） 对最顶层的UIView使用自定义类：

/// the target view (textView) which should not dismiss the keyboard
var KeyboardDismissingUIViewTarget: UIView?

/**
* Custom class for top view that dismisses keyboard when tapped outside the given textView or textField
*
* @author Alexander Volkov
* @version 1.0
*/
class KeyboardDismissingUIView: UIView {

    override func hitTest(point: CGPoint, withEvent event: UIEvent?) -> UIView? {
        if let targetView = KeyboardDismissingUIViewTarget as? UITextView {

            // Convert the point to the target view's coordinate system.
            // The target view isn't necessarily the immediate subview
            let pointForTargetView = targetView.convertPoint(point, fromView: self)

            if CGRectContainsPoint(targetView.bounds, pointForTargetView) {
                return targetView.hitTest(pointForTargetView, withEvent: event)
            }
            else {
                KeyboardDismissingUIViewTarget = nil
                targetView.resignFirstResponder()
                return nil
            }
        }
        return super.hitTest(point, withEvent: event)
    }
}

尝试scrollView.userInteractionEnabled=NO？好吧，这是可行的，但现在我有一个问题，我不能与位于同一位置的UITables交互。

/// the target view (textView) which should not dismiss the keyboard
var KeyboardDismissingUIViewTarget: UIView?

/**
* Custom class for top view that dismisses keyboard when tapped outside the given textView or textField
*
* @author Alexander Volkov
* @version 1.0
*/
class KeyboardDismissingUIView: UIView {

    override func hitTest(point: CGPoint, withEvent event: UIEvent?) -> UIView? {
        if let targetView = KeyboardDismissingUIViewTarget as? UITextView {

            // Convert the point to the target view's coordinate system.
            // The target view isn't necessarily the immediate subview
            let pointForTargetView = targetView.convertPoint(point, fromView: self)

            if CGRectContainsPoint(targetView.bounds, pointForTargetView) {
                return targetView.hitTest(pointForTargetView, withEvent: event)
            }
            else {
                KeyboardDismissingUIViewTarget = nil
                targetView.resignFirstResponder()
                return nil
            }
        }
        return super.hitTest(point, withEvent: event)
    }
}
