Facebook SDK + iPhone SDK + SSO

Question

我知道這個問題已被問到，但我一直在通過線程閱讀，並應用了所有我能找到的修復程序，並且仍然存在問題。

我想實現Facebook SDK的新SSO功能，以允許我的應用程序使用Facebook的應用程序而不是webView進行身份驗證。當我的應用切換到Facebook的應用時，它表示加載幾秒鐘並切換回來，但令牌仍爲空。我有一種感覺它與我的應用程序的URL方案做的，但我已經跟着很多教程和我相當有信心，我目前的plist值是正確的：

這裏是代碼我在我的appDelegate實現，的viewController文件： appDelegate.h

Facebook *facebook; 

appDelegate.m

// Pre 4.2 support 
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url { 
    return [facebook handleOpenURL:url]; 
} 

// For 4.2+ support 
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url 
    sourceApplication:(NSString *)sourceApplication annotation:(id)annotation { 
    return [facebook handleOpenURL:url]; 
} 

SecondViewController.m

-(IBAction) fbButton { 
    //FACEBOOK INTEGRATION 
    appDelegate.facebook = [[Facebook alloc] initWithAppId:@"222087841143437" andDelegate:appDelegate]; 

    // Check and retrieve authorization information 
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
    if ([defaults objectForKey:@"FBAccessTokenKey"] 
     && [defaults objectForKey:@"FBExpirationDateKey"]) { 
     appDelegate.facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"]; 
     appDelegate.facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"]; 
    } 
    if (![appDelegate.facebook isSessionValid]) { 
     appDelegate.facebook.sessionDelegate = self; 
     [appDelegate.facebook authorize:permissions]; 
     NSLog(@"Token: %@", [defaults objectForKey:@"FBAccessTokenKey"]); 
    } else { 
     NSLog(@"Already logged in!"); 

    } 
    [appDelegate.facebook requestWithGraphPath:@"me" andDelegate:self]; 

} 


- (void)request:(FBRequest *)request didLoad:(id)result { 
    NSString *nameID = [[NSString alloc] initWithFormat:@"%@ (%@)", [result objectForKey:@"name"], [result objectForKey:@"id"]]; 
    NSMutableArray *userData = [[NSMutableArray alloc] initWithObjects: 
           [NSDictionary dictionaryWithObjectsAndKeys: 
           [result objectForKey:@"id"], @"id", 
           nameID, @"name", 
           [result objectForKey:@"picture"], @"details", 
           nil], nil]; 

    [userData release]; 
    [nameID release]; 
    NSLog(@"DATA RECEIVED: %@", result); 
} 

- (void)request:(FBRequest *)request didReceiveResponse:(NSURLResponse *)response { 
    NSLog(@"request:didReceiveResponse:"); 
} 

- (void)request:(FBRequest *)request didFailWithError:(NSError *)error { 
    NSLog(@"%@", [error localizedDescription]); 
    NSLog(@"Err details: %@", [error description]); 
}; 
- (void)fbDidLogin { 
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
    [defaults setObject:[[appDelegate facebook] accessToken] forKey:@"FBAccessTokenKey"]; 
    [defaults setObject:[[appDelegate facebook] expirationDate] forKey:@"FBExpirationDateKey"]; 
    [defaults synchronize]; 
    NSLog(@"Facebook Logged in!"); 

    [appDelegate.facebook requestWithGraphPath:@"me" andDelegate:self]; 


} 

我知道我調用了[appDelegate.facebook requestWithGraphPath：@「me」andDelegate：self]兩次，但我不認爲這是問題所在。

下面是從控制檯的一個片段，當我按下登錄按鈕：

我欣賞的幫助，我真的希望我沒有錯過在這裏解決了這個問題的討論。這裏有幾個（許多的），我已經通過閱讀並找到解決辦法

確保沒有成功的Facebook應用程序（你在Facebook上創建的實際應用）不處於沙盒模式，並且如果確保用戶您的Facebook應用程序（iPhone Facebook客戶端）當前已登錄，則該應用程序是該應用程序的開發人員。
