今天有人问我collectionView 的左滑和 cell中的左滑手势冲突怎么处理
目前有两个处理方式 适用于 UIscrollView UItableView UICollection 等
1.让手势共同存在
```
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
NSLog(@"当前手势:%@; 另一个手势:%@", gestureRecognizer, otherGestureRecognizer);
return YES;
}
```
2.使用hitTest响应者链
```
-(UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event
{
NSString *className=NSStringFromClass([[super hitTest:point withEvent:event] class]);
if ([className isEqualToString:@"你的含有手势的类名"]) {
self.collectionView.scrollEnabled=NO;
return [super hitTest:point withEvent:event];
}
else
{
self.collectionView.scrollEnabled=YES;
return [super hitTest:point withEvent:event];;
}
}
```
