[rootNav setViewControllers:vcArray animated:YES]; 如何解决重置ViewControllers 过度动画时出现推进的控制器背景白色问题呢

[ETmanwenhan]

想通过实现该方法来达到删除前一个控制器，但是过度的时候会出现卡顿问题

• (void)setViewControllers:(NSArray<UIViewController > )viewControllers animated:(BOOL)animated

[ETmanwenhan]

我这样子实现系统方法：

• (void)setViewControllers:(NSArray<UIViewController > )viewControllers animated:(BOOL)animated { NSMutableArray * tempViewControllers = [NSMutableArray array];

  [viewControllers enumerateObjectsUsingBlock:^(__kindof UIViewController _Nonnull obj, NSUInteger idx, BOOL _Nonnull stop) { if ([obj isKindOfClass:[JKInterLayerViewController class]]) { [tempViewControllers addObject:obj]; } else { obj.jk_rootNavigationController = self; JKInterLayerViewController * interlayerViewController = [JKInterLayerViewController jk_interlayerViewControllerWithRootViewController:obj]; [tempViewControllers addObject:interlayerViewController]; } }];

  [super setViewControllers:tempViewControllers animated:animated]; }
