手势的话,有一个可以解决这个问题的API方法,如果otherGestureRecognizer这个手势没有执行成功的话,才会执行调用这个方法的手势。
- (void)requireGestureRecognizerToFail:(UIGestureRecognizer *)otherGestureRecognizer
- (UIScreenEdgePanGestureRecognizer *)screenEdgePanGestureRecognizer//获取边缘返回手势
{
UIScreenEdgePanGestureRecognizer *screenEdgePanGestureRecognizer = nil;
if (self.navigationController.view.gestureRecognizers.count > 0) {
for (UIGestureRecognizer *recognizer in self.navigationController.view.gestureRecognizers){
if ([recognizer isKindOfClass:[UIScreenEdgePanGestureRecognizer class]]) {
screenEdgePanGestureRecognizer = (UIScreenEdgePanGestureRecognizer *)recognizer;
break;
}
}
}
return screenEdgePanGestureRecognizer;
}
我们在操作滚动视图的时候的,只要滚动视图的手势能够触发,就不会执行滑动返回的那个手势,并且除了这个滚动视图外,在其他地方对滑动返回没有影响。
[[self screenEdgePanGestureRecognizer] requireGestureRecognizerToFail:self.scrollView.panGestureRecognizer];
