iphone - EXC_BAD_ACCESS 当 popViewControllerAnimated 在基于导航的应用程序中时

Question

我不明白为什么在弹出回导航堆栈中的上一个 View Controller 时会崩溃。问题是我正在使用自定义导航栏(原始导航栏被隐藏，我的自定义按钮触发导航 - 推送和弹出 - 相反)。

我得到的痕迹:

Program received signal:  “EXC_BAD_ACCESS”.

我遇到了同样的问题，可能是因为您的最后一个 View 不再保留。最好的方法可能是尝试通过创建属性并合成它来保留您之前的 View 。

然后尝试使用

[self.navigationConroller popViewControllerAnimated:YES];

或弹出所需 View

[self.navigationController popToViewController:myview animated:YES];

或弹出到 Root View

[self.navigationController popToRootViewControllerAnimated:YES];

如果它对您有帮助，请告诉我。因为当您尝试转到已发布的 View 时会出现此错误。
