使用FacebookSDK获取Facebook登录用户的朋友列表 [英] Get friend list of facebook login user using FacebookSDK

问题描述

我想在我的iphone应用程序中使用FacebookSDK访问朋友列表和他们的个人资料照片。
请建议一个演示或代码。

解决方案

  [FBRequestConnection startForMyFriendsWithCompletionHandler：^ （FBRequestConnection * connection，
 NSDictionary * result，
 NSError * error）{
 
 NSArray * data_array = [result objectForKey：@data]; //数组的朋友
 NSMutableArray *图片= [NSMutableArray数组]; //数组的图片
 
 for（NSDictionary * friend in data_array）
 {
 NSString * friend_id = friend [@id]; 
 NSString * urlString = [NSString stringWithFormat：@https://graph.facebook.com/%@/picture，friend_id]; 
 NSURL * url = [NSURL urlWithString：urlString]; 
 [图片addObject：[NSData dataWithContentsOfURL：url]]; 
 
} 
}]; 
  

由于 [NSData dataWithContentsOfURL：url] 很慢，你可能会考虑在后台运行这个代码

解决方案

[FBRequestConnection startForMyFriendsWithCompletionHandler:^(FBRequestConnection *connection,
                                                                  NSDictionary* result,
                                                                  NSError *error) {

            NSArray        *data_array = [result objectForKey:@"data"]; //array of friends
            NSMutableArray *pictures = [NSMutableArray array]; // array for pictures               

            for (NSDictionary *friend in data_array)
            {
                NSString *friend_id = friend[@"id"];
                NSString *urlString = [NSString stringWithFormat:@"https://graph.facebook.com/%@/picture",friend_id];
                NSURL    *url       = [NSURL urlWithString:urlString];
               [pictures addObject:[NSData dataWithContentsOfURL:url]];

            }
        }];

Since [NSData dataWithContentsOfURL:url] is pretty slow you may consider running this code in background
