禁用/启用UIPageViewController中的滚动 [英] Disable/enable scrolling in UIPageViewController

问题描述

我有一个 viewController ，它继承自 UIPageViewController （ @interface PageScrollViewController：UIPageViewController ）现在我想知道如何启用和禁用 UIPageViewController 中的滚动？使用 UIScrollView 时，你会做 setScrollEnabled：NO 和 self.view.userInteractionEnabled = NO ; 不是一个选项，因为这会阻止整个 UIView ，而不仅仅是滚动。

I got a viewController which inherits from UIPageViewController ( @interface PageScrollViewController : UIPageViewController ) Now I'm wondering how I can enable and disable the scrolling from the UIPageViewController? When using a UIScrollView you would do setScrollEnabled:NO and self.view.userInteractionEnabled = NO; isn't an option since this blocks the whole UIView instead of just the scrolling.

编辑
这是在 PageScrollViewController：UIPageViewController 类：

if ([[notification name] isEqualToString:@"NotificationDisable"]){
    NSLog (@"Successfully received the disable notification!");
    for (UIGestureRecognizer *recognizer in self.gestureRecognizers) {
        recognizer.enabled = NO;
    }
}

推荐答案

尝试循环遍历 UIPageViewController 的 gestureRecognizers 并禁用/启用它们：

Try looping through the gestureRecognizers of the UIPageViewController and disable/enable them:

for (UIGestureRecognizer *recognizer in pageViewController.gestureRecognizers) {        
        recognizer.enabled = NO;
}

注意：在这个SO帖子，此方法仅适用于 UIPageViewControllerTransitionStylePageCurl 。你可能想尝试这个解决方案（虽然看起来有点像hacky）。

Note: as found in this SO post, this method will only work for UIPageViewControllerTransitionStylePageCurl. You may want to try this solution (although it seems to be a bit hacky).
