發生故障當我pushViewController

最近，一個奇怪的問題發生時，我把ViewController推到下一個viewController。爲什麼我認爲這是一個奇怪的問題？因爲它並不總是出現（發生的可能性很低）。當它出現時，下一個viewController只在屏幕上顯示其導航欄，我仍然可以看到rootViewController，但沒有反應就觸摸它（PopGesture是有效的）。希望能得到你的幫助，非常感謝。發生故障當我pushViewController

你能在一些代碼中編輯你的文章嗎？ –

好吧，等待幾分鐘 – wakakaJP

因爲這個問題可能發生在我所有的根視圖控制器上，所以我懷疑基本視圖控制器有問題，但我找不到它 – wakakaJP

我想你應該改變

[super pushViewController:viewController animated:animated];

到

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

而同樣的，當彈出

[super popViewControllerAnimated:animated];

到

[self.navigationController popViewControllerAnimated:animated];

你懷疑代碼是我的UINavgationController的包裝子類，所以我認爲你所說的無法解決我的問題，但我會朝這個方向努力，謝謝你的幫助。 – wakakaJP

我清楚的Xcode的高速緩存，這種情況不會出現。也許我導入了第三個lib之前導致了這種情況。但是就像我問的那樣，它並不總是出現（發生的概率很低）。所以，希望它一直很好。

這個問題再次發生，我會從手勢識別器 – wakakaJP
