【中文标题】UINavigationController 不适用于 SearchDisplay 控制器

【英文标题】：UINavigationController not work with SearchDisplay Controller

【发布时间】：2013-12-23 12:36:15

【问题描述】：

在我的项目中使用侧边菜单。它是来自 gitHub 的现成模板，但问题是有时 searchDisplay 控制器正常工作，有时会出错，实际问题是什么我不明白......请帮助我

side menu template contain this files:
1)JWSlideMenuController
2)JWNavigationController
3)JWSlideMenuViewController

这里抛出错误

如果从 JWNavigationController.m 隐藏此代码，则 searchDisplayController 正在工作 rootViewController.navigationController = self;

但新问题是 UITableVIew didselectrowatindexpath 不起作用.. 我该怎么办？

【问题讨论】：

在 JWNavigationController.h 文件中应该是 UINavigationController 而不是 UIViewController。原因是导航控制器中存在 isNavigationBarHidden。此外，如果您使用的是导航控制器，那么崩溃的原因是您正在使用的 JWNavigationViewController 正在从内存中删除，即您可能正在从内存中删除该对象，或者它正在自动释放。尝试检查以上两个原因，一些解决方案将帮助您摆脱这种情况。

你能帮我做其他你告诉我的事情，但它的显示错误 2013-12-23 05:22:28.161 MyProject[764:13d03] *** 由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序'，原因：'不能直接在控制器管理的 UINavigationBar 上调用 pushNavigationItem:animated:。' ***第一掷调用堆栈：（0x197a012 0x1296e7e 0x1979deb 0x258362 0x4361 0x11288 0x28a285 0x28a4ed 0xc945b3 0x1939376 0x1938e06 0x1920a82 0x191ff44 0x191fe1b 0x18d47e3 0x18d4668 0x1daffc 0x5de2 0x1fa5）的libc ++ abi.dylib：终止称为抛出异常跨度>

你到底做了什么？可以贴一些代码吗？

另外，请查看***.com/questions/2520912/…

【参考方案1】：

isNavigationBarHidden: 是一个选择器，仅在派生自 UINavigationController 的类中可用。你必须修改这一行：

@interface JWNavigationController : UIViewController

用这个：

@interface JWNavigationController : UINavigationController

【参考方案2】：

您的JWNavigationController 不继承自UINavigationController。 但是isNavigationBarHidden是UINavigationController实现的方法。

现在看看错误（它使用术语“选择器”，但它指的是方法）：它基本上说你的JWNavigationController 的实例没有实现isNavigationBarHidden，这就是问题所在。

会不会是你打错​​字了，打算写：

@interface JWNavigationController : UINavigationController <UINavigationBarDelegate>
