大问题，容易Three20

Question

我不知道为什么，但是当我开始我的应用程序时，我从头开始2“返回” - 在我的导航器中的可能性。

因此，这里是我的代码：

#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 

这是无论哪个查看我尝试添加此：

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

每个视图，甚至一个完整的空单，参考2次“回”从我的应用程序的开始到自己。

Answer 1

找到它的2小时进行此bug一个总的工作时间之后，...

相反

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

[AdminViewController类]];

它应该是

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

[AdminViewController类]];
