在我的 iPhone 应用上从 Facebook 获取朋友信息答案

【问题描述】：

我正在开发一个使用 facebook 的 iPhone 应用程序。我需要获取我的数据（当前用户的数据）。

我确定我进行了正确的登录并获得了适当的权限。

现在，

我想要一个带有数据的 NSArray，并用 NSLog 打印出来哦。

我已经为好友列表做了这个，我没有问题：

-(IBAction)friendsInfo:(id)sender{

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

  }

- (void)request:(FBRequest *)request didLoad:(id)result {
    //ok so it's a dictionary with one element (key="data"), which is an array of dictionaries, each with "name" and "id" keys
    items = [(NSDictionary *)result objectForKey:@"data"];
    for (int i=0; i<[items count]; i++) {
        NSDictionary *friend = [items objectAtIndex:i];
        long long fbid = [[friend objectForKey:@"id"]longLongValue];
        NSString *name = [friend objectForKey:@"name"];
        NSLog(@"id: %lld - Name: %@", fbid, name);
    }
}

但对于我的信息，相同的方法不起作用：

-(IBAction)myInfo:(id)sender{

    // get information about the currently logged in user
    [facebook requestWithGraphPath:@"me" andDelegate:self];

     }

有人可以帮我吗？

使用此功能获取您的facebook信息（登录用户信息）

- (void)fetchUserDetails {
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               @"SELECT uid, name, pic FROM user WHERE uid=me()", @"query",nil];

[fb requestWithMethodName:@"fql.query"
                                 andParams:params
                             andHttpMethod:@"POST"
                               andDelegate:self];

}

感谢您的出色解决方案。我的代码的问题是返回的数据。我已经理解了这个方法的解决方案： - (void)request:(FBRequest *)request didLoad:(id)result { //Get a description of Result NSLog(@"\nDESCRIPTION: %@", [result description]) ; }
不客气 .. 你可以通过接受答案在 SO 中说声谢谢 :)

          -(void)addList:(FBSession *)session {
    NSString* fql = [NSString stringWithFormat:
                     @"select uid from user where uid == %lld",    session.uid];

    NSDictionary* params = [NSDictionary dictionaryWithObject:fql forKey:@"query"];
    sessionView = session;
    [[FBRequest requestWithDelegate:self] call:@"facebook.friends.get" params:params];


}

         - (void)request:(FBRequest*)request didLoad:(id)result {
    if(myList==nil) {
        NSArray* users = result;
        myList =[[NSArray alloc] initWithArray: users];
        for(NSInteger i=0;i<[users count];i++) {
            NSDictionary* user = [users objectAtIndex:i];
            NSString* uid = [user objectForKey:@"uid"];
            NSString* fql = [NSString stringWithFormat:
                         @"select name from user where uid == %@", uid];

            NSDictionary* params = [NSDictionary dictionaryWithObject:fql          forKey:@"query"];
            [[FBRequest requestWithDelegate:self] call:@"facebook.fql.query"     params:params];
        }
    }
    else {
        NSArray* users = result;
        NSDictionary* user = [users objectAtIndex:0];
        NSString* name = [user objectForKey:@"name"];
        txtView.text=[NSString     localizedStringWithFormat:@"%@%@,\n",txtView.text,name];
    }
}
