iPhone開發獲取用戶的個人資料姓名，電子郵件使用fbconnect API

Question

我對Facebook的使用這個牆張貼從我的iPhone應用程序

kAppId =@"zsdgdfgjhjk"; 
    if (!kAppId) { 
     NSLog(@"missing app id!"); 
     exit(1); 
     return nil; 
    } 

    if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) { 
     _permissions = [[NSArray arrayWithObjects: 
          // @"read_stream", @"publish_stream", @"offline_access",@"user_events",@"friends_events",@"rsvp_event",nil] retain]; 
          @"read_stream",@"email", @"publish_stream", @"offline_access",@"user_events",@"friends_events",@"rsvp_event",@"create_event",nil] retain]; 
     _facebook = [[Facebook alloc] initWithAppId:kAppId 
             andDelegate:self]; 



- (IBAction)publishStream:(id)sender { 

    SBJSON *jsonWriter = [[SBJSON new] autorelease]; 

    NSDictionary* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys: 
                  @"Always Running",@"text",@"http://itsti.me/",@"href", nil], nil]; 

    NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks]; 
    NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys: 
           @"a long run", @"name", 
           @"The Facebook Running app", @"caption", 
           @"it is fun", @"description", 
           @"http://itsti.me/", @"href", nil]; 
    NSString *attachmentStr = [jsonWriter stringWithObject:attachment]; 
    NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys: 
            @"Share on Facebook", @"user_message_prompt", 
            actionLinksStr, @"action_links", 
            attachmentStr, @"attachment", 
            nil]; 

    [_facebook dialog:@"publish.stream" 
      andParams:params 
      andDelegate:self]; 
} 

牆上張貼會不錯，但現在我想獲得用戶的Facebook個人資料名稱加電子郵件這個我想用戶登錄後，該代碼

[_facebook requestWithGraphPath:@"me?fields=id,name,email" andDelegate:self]; 

和

- (void)request:(FBRequest *)request didLoad:(id)result 
{ 
    if ([result isKindOfClass:[NSDictionary class]]){ 

     username = [result objectForKey:@"name"]; 
     } 
} 

，但它不是w ^甚至連這個簡單的代理方法- (void)request:(FBRequest *)request didLoad:(id)result，都沒有被調用。指導，我一直在這裏呆了很長時間。提前致謝。問候，薩德。

試試這個方法：

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

，你會解析響應這樣：

- (void)request:(FBRequest *)request didLoad:(id)result { 
    if ([result isKindOfClass:[NSArray class]]){ 
     result = [result objectAtIndex:0]; 
    } 
    if ([result objectForKey:@"owner"]) { 
    }else{ 
       NSLog(@"response is %@", result);  
     NSString *email =[result objectForKey:@"email"]; 
     NSString *userFbId =[result objectForKey:@"id"]; 
       // grab other fields 
    } 
}
