Question

在iOS7中，我们有一个新的＆＃34;从左到右滑动＆＃34;手势，这是一个非常有用的功能，但现在我有一个问题。

我使用此代码自定义UINavigationBar中的后退按钮。

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:view];

但是这会禁用从左到右滑动＆＃34;＆＃34;手势，所以我使用跟随代码来保持手势。

self.navigationController.interactivePopGestureRecognizer.delegate = self

然后，我发现手势异常，如果当前的ViewController有一个tableView，当tableView滚动时，手势就不会被触发。现在手势无法轻易触发，是否有某种方法可以解决？

Answer 1

此代码适用于我。

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldBeRequiredToFailByGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return [gestureRecognizer isKindOfClass:UIScreenEdgePanGestureRecognizer.class];
}

Answer 2

将interactivePopGestureRecognizer.delegate设置为self只是第一步。第二步是实施

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
    return ![otherGestureRecognizer isKindOfClass:UIPanGestureRecognizer.class];
}

在交互式弹出窗口正在进行时，需要对平移手势识别器进行测试以阻止滚动或表格视图的垂直滚动。

Answer 3

添加类控制器“UIGestureRecognizerDelegate”

在ViewDidApper中添加

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)

    self.navigationController?.interactivePopGestureRecognizer.delegate =  self
}
