TTSplitViewController用的UITabBarController

我在這我想顯示在左側窗格中的UITabBarController一個TTSplitViewController，通過代碼：這裏TTSplitViewController用的UITabBarController

@implementation SplitAppController 

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { 
    if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) { 
     [self setupURLRouting]; 
    } 

    return self; 
} 

- (void)setupURLRouting { 
    [self routePrimaryNavigator]; 
    [self routeDetailsNavigator]; 
} 

- (void)routePrimaryNavigator { 

    TTURLMap* map = self.primaryNavigator.URLMap; 

    // Forward all unhandled URL actions to the right navigator. 
    [map from: @"*" toObject: self selector: @selector(willOpenUrlPath:)]; 
    [map from:@"tt://primary" toViewController:[RootViewController class]]; 
}

RootViewController的是一個的UITabBarController。但是，我收到以下錯誤：

如何解決此問題？

似乎你的代碼期望RootViewController成爲UINavigationController的子類。

如果您沒有編寫該代碼，您可以創建一個UINavigationController子類，並使用標籤欄控制器將其初始化爲根視圖控制器，並隱藏導航欄，我認爲這會給出您正在查看的結果對於。

我的答案因爲沒有明顯的原因而被否決 - – EmilioPelaez

Jep。這也適用於我。 – DAS

這是正確的

[map from:@"tt://primary" toViewController:[RootViewController class]];

我的建議是

[map from:@"tt://primary" toViewController:RootViewControllerobject];

EmilioPelaez是完全正確的，我只是成功了，像這樣類似的解決方案，和它的作品！

@implementation MainViewController 

- (id)initWithNavigatorURL:(NSURL *)URL query:(NSDictionary *)query { 
    MainTabBarController *mainTabBarController = [[MainTabBarController alloc] init]; 
    [mainTabBarController setTabURLs:[NSArray arrayWithObjects: 
             @"tt://firstLink", 
             @"tt://secondLink", 
             nil]]; 

    self = [super initWithRootViewController:mainTabBarController]; 
    [mainTabBarController release]; 
    self.navigationBarHidden = YES; 
    return self; 
} 

@end

我找到了另一種方式，使其工作（也許是減少代碼的複雜性更好的辦法）：

繼承的UITabBarController這種額外的方法：

- (UIViewController *)topViewController { 
    return self; 
}

它完美。
