uiscrollview上的 uipangesturerecognizer冲突

最近在tableview里的cell imageview加了个 uipangesturerecognizer发现优先滚动imageview，往上拖的时候，tableView不响应滚动了，原来是tableview的实现也是用了uipangesturerecognizer。解决方案如下：

实现 UIGestureRecognizerDelegate

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{

return YES;//uitableview和子view也响应 no只响应子view uipangesturerecognizer

}
