Question

在我的程序中有两个视图（scrollView-super，view-sub * 2）。

在我的例子中，两个子视图在scrollView中进行了子视图。在子视图中调用touchesBegan事件。

如何在scrollView ???中获取事件

@interface MyScrollView:UIScrollView
...
@implement MyScrollView
...
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    //here is my code
    //but I can't get event here
   ...
}
-(id)initWithFrame:(CGRect) frame
{
...
    MyView *view1 = [[MyView alloc] initWithFrame:(0, 0, 320, 240);
    MyView *view2 = [[Myview alloc] initWithFrame:(0, 240, 320,240);
    [self addSubview: view1];
    [self addSibvoew: view2];
...
}

@interface MyView:UIView
...
@implement MyScrollView
...
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
   //break points 
   //here comes event
}

Answer 1

试试这段代码..

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapGestureCaptured:)];

[scroll addGestureRecognizer:singleTap];

- (void)singleTapGestureCaptured:(UITapGestureRecognizer *)touch{
    CGPoint touchPoint=[gesture locationInView:scrollView]; 
    touchPoint = [touch locationInView:self.view];  
}

我建议将你的两个子视图设为全局，然后在superview中使用touchesbegan方法将触摸和事件传递给子视图进行处理。有些像[view1 touchesBegan：touches event：event]; 我没有测试过，但这应该是一种方式。
