我不知道为什么，但是当我启动我的应用程序时，我的导航器从一开始就有 2 个“返回”-可能性。

所以这是我的代码：

#import "AnAppDelegate.h"
#import "LoginViewController.h"
#import "MainScreenViewController.h"
#import "AdminViewController.h"
#import "Three20/Three20.h"


@implementation AnAppDelegate

@synthesize window = _window;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

    [self.window makeKeyAndVisible];

    TTNavigator* navigator = [TTNavigator navigator];
    navigator.persistenceMode = TTNavigatorPersistenceModeAll;
    TTURLMap* map = navigator.URLMap;
    [map from:@"*" toViewController:[TTWebController class]];
    [map from:@"tt://launcher/" toViewController:
    [AdminViewController class]];

    if (![navigator restoreViewControllers]) {
        [navigator openURLAction:
         [TTURLAction actionWithURLPath:@"tt://launcher"]];
    }

    return YES;
}

- (BOOL)application:(UIApplication*)application handleOpenURL:(NSURL*)URL {
    [[TTNavigator navigator] openURLAction:[TTURLAction actionWithURLPath:URL.absoluteString]];
    return YES;
}



- (void)applicationWillResignActive:(UIApplication *)application
{
    /*
     Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
     Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
     */
}

- (void)applicationDidEnterBackground:(UIApplication *)application
{
    /*
     Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later. 
     If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
     */
}

- (void)applicationWillEnterForeground:(UIApplication *)application
{
    /*
     Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
     */
}

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    /*
     Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
     */
}

- (void)applicationWillTerminate:(UIApplication *)application
{
    /*
     Called when the application is about to terminate.
     Save data if appropriate.
     See also applicationDidEnterBackground:.
     */
}

- (void)dealloc
{
    [_window release];
    [super dealloc];
}


@end

无论我尝试在此处添加哪个视图：

[map from:@"tt://launcher/" toViewController:
[AdminViewController class]];

从我的应用程序开始，每个视图，甚至是一个完全空的视图，都会引用 2 次“回到”自身。

在这个错误的总工作时间为 2 小时后找到它......

反而

[map from:@"tt://launcher/" toViewController:

[AdminViewController 类]];

它应该是

[map from:@"tt://launcher/" toSharedViewController:

[AdminViewController 类]];
