FB請求輸出在iOS中不起作用

我的FB請求輸出在iOS中不起作用。它輸出兩次到控制檯。第一次輸出正確的信息，然後立即用（空）代替正確的數據做同樣的事情。FB請求輸出在iOS中不起作用

這裏是我的代碼：

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

{

facebook = [[Facebook alloc] initWithAppId:@"fbKEY....." andDelegate:self]; 

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
if ([defaults objectForKey:@"FBAccessTokenKey"] 
    && [defaults objectForKey:@"FBExpirationDateKey"]) { 
    facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"]; 
    facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"]; 
} 

//FB check for valid session 


if (![facebook isSessionValid]) { 
    NSArray *permissions = [[NSArray alloc] initWithObjects: 
          @"user_likes", 
          @"read_stream", 
          @"user_location", 
          @"user_checkins", 
          // @"publish_actions", 
          // @"user_activities", 
          // @"friends_birthday", 
          nil]; 

    [facebook authorize:permissions]; 

} 


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


// get the posts made by the "platform" page 
[facebook requestWithGraphPath:@"platform/posts" andDelegate:self]; 

// get the logged-in user's friends 
[facebook requestWithGraphPath:@"me/friends" andDelegate:self]; 

[facebook dialog:@"feed" andDelegate:self]; 

// Override point for customization after application launch. 
return YES;

}

- (void)request:(FBRequest *)request didLoad:(id)result { 

NSDictionary *userData = (NSDictionary *)result; // The result is a dictionary 

NSString *name = [userData objectForKey:@"name"]; 
NSString *location = [[userData objectForKey:@"location"] objectForKey:@"name"]; 
NSString *gender = [userData objectForKey:@"gender"]; 

NSLog(@"name is %@", name); 
NSLog(@"location is %@", location); 

NSLog(@"gender is %@", gender); 

// NSLog(@"%@",result); 

}

，這裏是我的NSLog輸出：

2012-04-04 16:42:56.440 Whatto[86350:15803] name is John Doe 
2012-04-04 16:42:56.441 appName[86350:15803] location is London

您必須展示更多代碼。特別是您創建請求的方法 – Zalykr 2012-04-04 15:50:16

我添加了didFinishLaunchingWithOptions方法。 – hanumanDev 2012-04-04 15:53:28

您是否真的嘗試過對'request didLoad'方法進行突破並檢查Facebook返回的內容？這可能會告訴你什麼問題是... – lxt 2012-04-04 15:55:07

您正在提出3個不同的請求和對待每個答案的結果是一個用戶... 第二個結果將是一個帖子的列表，第三個將是一個朋友列表。

祝你好運！
