Since we used the UIPageViewController control, no matter which system the model of the phone, every version always happens the same crash。 We use UIPageViewController control style is "UIPageViewControllerTransitionStyleScroll" , flip back and forth through "setViewControllers:" to set.We suspect that the crash is caused by a problem with the UIPageViewController control itself.Has anyone encountered it, and how should you avoid it
The crash log is as follows：

UIPageViewController init method is ：
"self.pageViewController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil]; self.pageViewController.delegate = self; self.pageViewController.dataSource = self;"Page turn Method is : [self.pageViewController setViewControllers:@[pageVC] direction:UIPageViewControllerNavigationDirectionReverse animated:animated completion:^(BOOL finished) { [weakObjc pageFinishedLogic]; }];
