当要响应的view，被另一个view挡住的时候可以使用事件穿透1.自定义view2.重写#pragma mark - UIView Overrides-(UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event{    //在这里返回你需要响应的view    }

- (void)viewDidLoad {    // 单击的 Recognizer    UITapGestureRecognizer* singleRecognizer;    singleRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:selfaction:@selector(handleSingleTapF

view的多触点是默认关闭的，所以只有设置multipleTouchEnabled＝yes，才能开启多触点

实现UIGestureRecognizerDelegate- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {    if (nowImageView) {        returnNO;  //忽略手势    }    returnYES;}

http://www.xuebuyuan.com/1225027.html让控件复写 -(UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event方法。 只有控件存在无论可见度是什么uikit框架会递归回调此接口。   若要subview响应touch事件，只需判断point是否在subview控件区域内，若在
