ios - 加载新 View 时如何禁用 UISwipeGestureRecognizer？

Question

在我设置的 viewDidLoad 中

UISwipeGestureRecognizer *swipeRecognizerU = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeUpDetected:)]; swipeRecognizerU.direction = UISwipeGestureRecognizerDirectionUp; [self.view addGestureRecognizer:swipeRecognizerU];

当我通过弹出窗口加载新 View 时，我需要禁用该手势

// show popup view
-(IBAction)showPopup:(id)sender
{
    MJDetailViewController *detailViewController = [[MJDetailViewController alloc] initWithNibName:@"MJDetailViewController" bundle:nil];
    [self presentPopupViewController:detailViewController animationType:MJPopupViewAnimationSlideBottomBottom];
}

弹出 View 关闭后，我需要重新设置滑动手势。

// hide popup view
-(IBAction)hidePopup:(id)sender
{
    [self dismissPopupViewControllerWithanimationType:MJPopupViewAnimationSlideBottomBottom];
}

如何做到这一点？

我认为 UIGestureRecognizer 有一个名为 enabled 的属性。你试过这个吗，禁用你的滑动应该没问题:

swipeGestureRecognizer.enabled = NO;
