ios - 在进行 interactivePopGestureRecognizer 转换时禁用滚动

Question

我已经实现了interactivePopGestureRecognizer。它过渡到上一页。但问题是，当转换发生时，如果当前 View Controller 中有一个 UIScrollView，它就会开始滚动。有什么办法可以预防吗？

我已在 RootViewcontroller 中添加了手势:

   self.appNavController = [[UINavigationController alloc] initWithRootViewController:controller];
    self.appNavController.interactivePopGestureRecognizer.enabled = YES;
    self.appNavController.interactivePopGestureRecognizer.delegate = (id<UIGestureRecognizerDelegate>)self;
    [self.appNavController setNavigationBarHidden:YES];

我称之为:

-(void)viewDidAppear:(BOOL)animated{

    [super viewDidAppear:animated];

    APP_DELEGATE.rootViewController.appNavController.interactivePopGestureRecognizer.enabled = NO;

}

-(void)viewWillDisappear:(BOOL)animated{

    [super viewWillDisappear:animated];

    APP_DELEGATE.rootViewController.appNavController.interactivePopGestureRecognizer.enabled = YES;

}

Answer 1

我找到了解决方案。在正在滑动的 View Controller 中，我添加了以下内容:

- (void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:animated];

    self.scrollView.scrollEnabled = YES;
}

- (void)viewWillDisappear:(BOOL)animated{
    [super viewWillDisappear:animated];

    self.scrollView.scrollEnabled = NO;
}

它就像一个魅力。
