尝试在NavigationController中推送多个UIViewControllers时出现iOS8问题 [英] iOS8 issue when trying to push multiple UIViewControllers in NavigationController

问题描述

我有6个UIViewControllers与push segues连接，在我的应用程序中使用标识符和功能跳转到所需的 UIViewController ，使用此方法堆叠ViewControllers：

I have 6 UIViewControllers connected with push segues with identifiers and a functionality in my app to 'jump' to the desired UIViewController using this method for stacking ViewControllers:

- (void) JumpTo6 {
UINavigationController *nav = self.navigationController;
UIViewController *a =[self.storyboard instantiateViewControllerWithIdentifier:@"2"];
[nav pushViewController:a animated:NO];
UIViewController *b =[self.storyboard instantiateViewControllerWithIdentifier:@"3"];
[nav pushViewController:b animated:NO];
UIViewController *c =[self.storyboard instantiateViewControllerWithIdentifier:@"4"];
[nav pushViewController:c animated:NO];
UIViewController *d =[self.storyboard instantiateViewControllerWithIdentifier:@"5"];
[nav pushViewController:d animated:NO];
UIViewController *e =[self.storyboard instantiateViewControllerWithIdentifier:@"6"];
[nav pushViewController:e animated:YES];

使用iOS7时一切正常。我会解雇这个方法，让我说我在 UIViewController 一，系统会将每个 UIViewController 堆叠到UI VC 6和 UIViewController 六个将显示动画。

When using iOS7 everything worked fine. I would fire this method, and let's say I was on UIViewController one, the system would stack every UIViewController up to UI VC 6 and UIViewController six would get presented with the animation.

但是在iOS8上会出现奇怪的行为。系统在短时间内向我显示 UIViewcontroller 5，然后转到 UIViewcontroller 6.这是我不想要。

But on iOS8 strange behaviour appears. The system shows me the UIViewcontroller 5 for a brief period of time, and then goes to UIViewcontroller 6. This is something I don't want.

总结一下：

iOS 7：1 ----- > 6 - 可取

iOS 7: 1 -----> 6 - desirable

iOS 8：1 -----> 5（短暂的一段时间）----> 6 - 不受欢迎

iOS 8: 1 -----> 5 (for a brief period of time) ----> 6 - undesirable

我的问题是如何使用iOS 8实现理想效果.Ty！

My question is how to achieve desirable effect using iOS 8. Ty!

推荐答案

使用方法：

- (void)setViewControllers:(NSArray *)viewControllers
              animated:(BOOL)animated

将所有控制器设置为仅显示最后一个控制器。

to set all the controllers at a time showing only the last.

在你的情况下：

- (void) JumpTo6 {
  UINavigationController *nav = self.navigationController;
  UIViewController *a = [self.storyboard instantiateViewControllerWithIdentifier:@"2"];
  UIViewController *b = [self.storyboard instantiateViewControllerWithIdentifier:@"3"];
  UIViewController *c = [self.storyboard instantiateViewControllerWithIdentifier:@"4"];
  UIViewController *d = [self.storyboard instantiateViewControllerWithIdentifier:@"5"];
  UIViewController *e = [self.storyboard instantiateViewControllerWithIdentifier:@"6"];
  NSArray *viewControllers = nav.viewControllers;
  NSArray *newViewControllers = [NSArray arrayWithObjects:a, b, c, d, e, nil];
  [nav setViewControllers:[viewControllers arrayByAddingObjectsFromArray:newViewControllers] animated:YES];
}
