问题描述
在iOS7中，我们有一个新的向左滑动手势，这是一个非常有用的功能，但现在我遇到了问题。
In iOS7, we have a new "swipe left to right" gesture, this is a very useful feature, but now I have a problem with it.
I使用此代码自定义 UINavigationBar 中的后退按钮。
I use this code to custom the back button in UINavigationBar.
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView：view];
但是这将禁用从左向右滑动手势，所以我使用按照代码保持手势启用。
but this will disables the "swipe left to right" gesture, so I use the follow code to keep the gesture enabled.
self.navigationController.interactivePopGestureRecognizer.delegate = self
然后，我发现手势工作异常，如果当前的ViewController有一个tableView，当tableView滚动时，手势将不会被触发。现在手势无法轻易触发，是否有某种方法可以修复它？
And then, I found that the gesture is working abnormal, if current ViewController has a tableView, when the tableView is scrolling, the gesture won't be triggered. Now the gesture can't be triggered easily, is there some way to fix it?
推荐答案
此代码对我来说很好。
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
return YES;
}
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldBeRequiredToFailByGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
return [gestureRecognizer isKindOfClass:UIScreenEdgePanGestureRecognizer.class];
}
