发生故障当我pushViewController

最近，一个奇怪的问题发生时，我把ViewController推到下一个viewController。为什么我认为这是一个奇怪的问题？因为它并不总是出现（发生的可能性很低）。当它出现时，下一个viewController只在屏幕上显示其导航栏，我仍然可以看到rootViewController，但没有反应就触摸它（PopGesture是有效的）。希望能得到你的帮助，非常感谢。发生故障当我pushViewController

你能在一些代码中编辑你的文章吗？ –

好吧，等待几分钟 – wakakaJP

因为这个问题可能发生在我所有的根视图控制器上，所以我怀疑基本视图控制器有问题，但我找不到它 – wakakaJP

我想你应该改变

[super pushViewController:viewController animated:animated];

到

[self.navigationController pushViewController:viewController animated:animated];

而同样的，当弹出

[super popViewControllerAnimated:animated];

到

[self.navigationController popViewControllerAnimated:animated];

你怀疑代码是我的UINavgationController的包装子类，所以我认为你所说的无法解决我的问题，但我会朝这个方向努力，谢谢你的帮助。 – wakakaJP

我清楚的Xcode的高速缓存，这种情况不会出现。也许我导入了第三个lib之前导致了这种情况。但是就像我问的那样，它并不总是出现（发生的概率很低）。所以，希望它一直很好。
