如何可靠地找到UIGestureRecognizer的正确视图？
|
我有一堆UIViews，如下图所示。红色/粉色（半透明）视图位于其他视图之上。
红色为
UISwipeGestureRecognizer
- (UIView*)hitTest:(CGPoint)point withEvent:(UIEvent *)event
{
UIView *hitView = [super hitTest:point withEvent:event];
if (hitView == self)
{
if (self.hasASwipeRecognizer)
return self; // What if this was a tap?
if (self.hasATapRecognizer)
return self;
else
return nil;
}
else
return hitView;
}

。例如，如果通过的手势识别器是滑动识别器，则检查触摸点是否在绿色视图内并返回“ 4”。否则返回ѭ6。 如果有类似的手势识别器，那么我建议您保留一个参考并进行验证。 用法- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch { CGPoint pointInView = [touch locationInView:gestureRecognizer.view]; if ( [gestureRecognizer isMemberOfClass:[UITapGestureRecognizer class]] && CGRectContainsPoint(self.blueView.frame, pointInView) ) { return YES; } if ( [gestureRecognizer isMemberOfClass:[UISwipeGestureRecognizer class]] && CGRectContainsPoint(self.greenView.frame, pointInView) ) { return YES; } return NO; }亨尖玛次酥

-(void)handleGesture:(UIGestureRecognizer*)gestureRecognizer { CGPoint touchPoint = [tapGestureRecognizer locationInView:viewUnderTest]; if ([viewUnderTest pointInside:touchPoint withEvent:nil]) { NSLog(@\"Hit done in view under test\"); } }
