iOS获取用户的Facebook ID和朋友列表与朋友的个人资料图片URL

Question

I want to get user id from Facebook and Friend list, with friends id & profile picture URL of friends. I've two code samples, first is

NSDictionary *params = @{@"fields": @"name, id, picture"};
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:@"/me/friends" parameters:params HTTPMethod:@"GET"];

this returns friend list with profile picture URL of friends too, but does not return user's own Facebook id. Second is

[[[FBSDKGraphRequest alloc] initWithGraphPath:@"/me" parameters:@{@"fields": @"id,name,friends, picture"}]

This returns user's Facebook id, friend list but doesn't return profile picture URL of friends. Can you help me out here, how can I get both things in one call ?

        if (!error) {
            if (!result.isCancelled) {
                NSDictionary *params = @{@"fields":@"id,name,email,picture,friends"};
                FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                                              initWithGraphPath:@"me"
                                              parameters:params
                                              HTTPMethod:@"GET"];
                [SVProgressHUD show];
                [request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
                    [SVProgressHUD dismiss];
                    if (!error) {

                       NSLog(@"%@",result); // here u get all require data              
                    }
                }];
            }
        }else{
            NSLog(@"%@",error.localizedDescription);  ?/ Handle Error Here.
        }
    }];

This is how I get this info for friends who are using my app

if ((FBSDKAccessToken.current()) != nil){

    if let request = FBSDKGraphRequest(graphPath: "me/friends", parameters: ["fields": "email, name, gender, picture"] ) {
         request.start(completionHandler: { (connection, result, error) in

             if (error == nil){
                  guard let userInfo = result as? [String: Any] else { return } //handle the error
                  print("data------:\(userInfo)")
             } else {

                  //handle any errors

             }
        }
    }
}

The userInfo has the data you need.

您可以使用此代码：

NSString *pictureURL = [NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?type=large&return_ssl_resources=1", facebookID];
