ios - 收到状态的CA回调，但事件状态队列为空

Question

我收到状态崩溃的UIPageViewController:Received CA回调，但是 Activity 状态队列为空。

Answer 1

我遇到了同样的错误，这是因为用户翻页太快，所以我不得不像这样降低用户的速度:

func pageViewController(_ pageViewController: UIPageViewController, willTransitionTo pendingViewControllers: [UIViewController]) {
    
    pageViewController.view.isUserInteractionEnabled = false
}

然后在

func pageViewController(_ pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool) {
    
    DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + 0.1, execute: {
        pageViewController.view.isUserInteractionEnabled = true
    })
}

如果您确定viewController速度很快，也可以忽略asynAfter。
