将触摸转移到父视图而不禁用子视图的用户交互

我在视图控制器的视图上有一个 UIView 。 UIView 上添加了平移手势。现在我想将触摸转移到父视图（视图控制器的视图），以便父视图也调用触摸委托方法，并且 UIView 也被平移。

取决于你想做什么。如果你想让视图控制器知道 UIView 子视图中发生了某些事情，你应该将主视图控制器的委托传递给子视图（面向对象编程方式）。像这样的事情：

// in child UIVIew 
...
id<mainControllerDelegate> _mainControllerDel; // This delegate was passed to the view by the main view controller 
...
-(void)gestureHappened
{
 [_mainControllerDel gestureHappenedInView];
}

但是如果您希望两个视图都对手势做出反应，您应该使用应与手势识别器同时识别 https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIGestureRecognizerDelegate_Protocol/index.html#//apple_ref/occ/intfm/UIGestureRecognizerDelegate/gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer手势委托方法，如下所示：

// In class that conforms to your UIGestureRecognizerDelegate 
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
     return YES; 
}

EDIT:

我刚刚读到你想要touchesBegan（和类似的）方法也在父级中调用。这不是任何 UI 的标准行为。请阅读iOS 事件响应链 https://developer.apple.com/library/ios/documentation/EventHandling/Conceptual/EventHandlingiPhoneOS/event_delivery_responder_chain/event_delivery_responder_chain.html。如果您确实希望调用链中的下一个视图，您可以覆盖子级的方法并调用下一个响应者。像这样：

// in child view
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
   [super touchesBegan:touches withEvent:event];
   [self.nextResponder touchesBegan:touches withEvent:event];
}

我会做类似的事情，但使用委托：

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
   [_mainControllerDel touchBeganOnView: self withEvent: event];
}
