我可以在子视图上调用 - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

Question

我在我的视图中识别出触摸 - 如果发生某些情况，我想用这个方法调用我的子视图，但它不起作用 - （如果我不覆盖 hittestWithEvent - 这个视图会被返回）

我该怎么做？

编辑：

我希望原始的 SUBVIEW 获得“点击”，所以我尝试这样做：

-(void)didTap:(MyTapGesture *)tap
{
    // the original view that would have been returned by hit test. could be any arbitrary view
    UIView *theView = [super hitTest:[tap locationInView:self] withEvent:nil];
    NSSet *touchesBegan = tap.touchesBegan;
    NSSet *touchesEnded = tap.touchesEnded;
    UIEvent *eventBegan = tap.eventBegan;
    UIEvent *eventEnd = tap.eventEnd;

    NSSet *tbegan = [eventBegan touchesForView:theView];
    NSSet *tend = [eventEnd touchesForView:theView];
    // try to simulate the touch in the subview - not working   
    [theView touchesBegan:tbegan withEvent:eventBegan];
    [theView touchesEnded:tend withEvent:eventEnd];
}

@interface MyTapGesture : UITapGestureRecognizer

@property (nonatomic,strong) NSSet *touchesBegan;
@property (nonatomic,strong) NSSet *touchesEnded;
@property (nonatomic,strong) UIEvent *eventBegan;
@property (nonatomic,strong) UIEvent *eventEnd;
@end

@implementation MyTapGesture

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    self.touchesBegan = touches;
    self.eventBegan = event;
    [super touchesBegan:touches withEvent:event];
}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    [super touchesMoved:touches withEvent:event];
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    self.touchesEnded = touches;
    self.eventEnd = event;
    [super touchesEnded:touches withEvent:event];
}
- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event
{
    [super touchesCancelled:touches withEvent:event];
}

@end

您可以在您的主视图上覆盖 touchesBegan:withEvent 并且条件发生在您的子视图上调用它：

//In your view
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    if (CONDITION)
    {
        //call your subview
        [yourSubview touchesBegan:touches withEvent:event];
    }
}

希望这就是你所追求的。

您可以尝试向您的子视图添加一个方法，该方法在满足条件时调用：

//In your subview
-(void)myMethod:(NSSet *)touches
{
    //Your code
}

并在你的视图中调用它：

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    if (CONDITION)
    {
        //call your subview
        [yourSubview myMethod:touches];
    }
}
