iphone - 使用UITabBarController而不是UINavigationController的ZUUIRevealController

我正在尝试将ZUUIRevealController实施到我的项目中，此应用程序使用带有3个选项卡的UITabBarController。

我多次进行了截屏和示例代码，但我不知道为什么

[self.navigationController.parentViewController respondsToSelector:@selector(revealToggle)]

仅以假回应。

在我的appdelegate中，我只创建一个简单的UITabBarController并添加为rootViewController：

UITableViewController *activityViewController = [[[ActivityViewController alloc] initWithNibName:@"ActivityViewController" bundle:nil] autorelease];
UIViewController *agendaViewController = [[[AgendaViewController alloc] initWithNibName:@"AgendaViewController" bundle:nil] autorelease];
UIViewController *settingsViewController = [[[SettingsViewController alloc] initWithNibName:@"SettingsViewController" bundle:nil] autorelease];

UINavigationController *activityNavController = [[[UINavigationController alloc] initWithRootViewController:activityViewController] autorelease];
UINavigationController *agendaNavController = [[[UINavigationController alloc] initWithRootViewController:agendaViewController] autorelease];
UINavigationController *settingsNavController = [[[UINavigationController alloc] initWithRootViewController:settingsViewController] autorelease];

self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:activityNavController, agendaNavController, settingsNavController, nil];

SortViewController *sortViewController = [[SortViewController alloc] init];
ZUUIRevealController *revealController = [[ZUUIRevealController alloc] initWithFrontViewController:self.tabBarController rearViewController:sortViewController];
[sortViewController release];

//self.window.rootViewController = self.tabBarController;
self.window.rootViewController = revealController;

[revealController release];

[self.window makeKeyAndVisible];

但是当我在ActivityViewController中进行检查时，我只会得到false

if([self.tabBarController.parentViewController respondsToSelector:@selector(revealToggle)])
{
    NSLog(@"YAY");
}
else
{
    NSLog(@"WRONG");
}

在截屏视频中看起来是如此简单，但是看起来我缺少了一些东西。

最佳答案

只需在检查:时将respondsToSelector:放在if语句中

if([self.tabBarController.parentViewController respondsToSelector:@selector(revealToggle:)])
