Question

我有一个带有“旧”Tabbarcontroller和MainWindow.xib的应用程序。我必须删除tabbarcontroller逻辑来转换应用程序并制作一个“左侧菜单”类型，如facebook。我有一个问题，我有alredy用tableviewcontroller创建左侧menù我可以打开，关闭并正确推送我的控制器...现在我想插入一个不同的customnavigation bar类每个导航控制器（在旧版本的app每个导航控制器都有自定义导航类来改变与活动viewcontroller相关的che图像。这是我在tableview中使用的代码在左侧菜单中选择了一行的方法：

 if (indexPath.row==1) {

    DemoViewController *demoController = [[DemoViewController alloc] init];
    UINavigationController *navigationController = self.menuContainerViewController.centerViewController;
    [navigationController setValue:[[CustomNavigationBar alloc]init] forKeyPath:@"navigationBar"];
    NSArray *controllers = [NSArray arrayWithObject:demoController];
    navigationController.viewControllers = controllers;
    [self.menuContainerViewController setMenuState:MFSideMenuStateClosed];
}

此代码正确管理幻灯片并正确加载MFSideMenu中的viewcontroller。自定义导航栏类已分配但无法正常工作：

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{

永远不会调用此方法，也许MFSideMenu会覆盖uinavigationcontroller委托？我怎样才能使这个导航控制器委托方法再次“激活”？

找到了解决方案，这段代码：

      DemoViewController *demoController = [[DemoViewController alloc] init];
    UINavigationController *navigationController = self.menuContainerViewController.centerViewController;

    CustomNavigationBar *navClass=[[CustomNavigationBar alloc]init];
    [navigationController setValue:navClass forKeyPath:@"navigationBar"];
    [navigationController setDelegate:navClass];

    NSArray *controllers = [NSArray arrayWithObject:demoController];
    navigationController.viewControllers = controllers;
    [self.menuContainerViewController setMenuState:MFSideMenuStateClosed];

而不是：

DemoViewController *demoController = [[DemoViewController alloc] init];
UINavigationController *navigationController = self.menuContainerViewController.centerViewController;
[navigationController setValue:[[CustomNavigationBar alloc]init] forKeyPath:@"navigationBar"];
NSArray *controllers = [NSArray arrayWithObject:demoController];
navigationController.viewControllers = controllers;
[self.menuContainerViewController setMenuState:MFSideMenuStateClosed];

通过这种方式正确分配了代表......

uinavigationcontrollerdelegate不适用于MFSideMenu
