使用社交框架登录并列出Facebook朋友

Question

有人可以给我一些关于如何整合这一点的指示吗？ 我的目标是获取安装我的应用程序（fb app）的朋友列表。 最初，我需要先将用户登录到我的应用程序，然后列出已经/尚未安装该应用程序的朋友。

PS：我不想使用Facebook SDK。 我过去做过噩梦，因为Facebook花费了无数次更改sdk的时间。

===========更新

我已经成功登录并列出了我的Facebook朋友。 但是现在要列出拥有该应用程序的朋友并列出图片也很困难。 我尝试了这个：

网址： https : //graph.facebook.com/me/friends?friends?fields=id，名称，已安装，图片

给我OAuthException : An active access token must be used to query information about the current user. 问题。

我也在API Graph中尝试过，它工作时没有提到错误。

如果我只尝试me/friends完美工作，它将列出我所有的朋友。

首先在您的项目中导入Social，Account，SystemConfiguration框架。 然后在您的.m文件中使用此代码

-(void)facebook
{
    self.accountStore = [[ACAccountStore alloc]init];
    ACAccountType *FBaccountType= [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

    NSString *key = @"XXXXXXXXXXXXX";//get your key form creating new app in facebook app section
    NSDictionary *dictFB = [NSDictionary dictionaryWithObjectsAndKeys:key,ACFacebookAppIdKey,@[@"email"],ACFacebookPermissionsKey, nil];

    [self.accountStore requestAccessToAccountsWithType:FBaccountType options:dictFB completion:
     ^(BOOL granted, NSError *e) {
         if (granted)
         {
             NSArray *accounts = [self.accountStore accountsWithAccountType:FBaccountType];
             //it will always be the last object with single sign on
             self.facebookAccount = [accounts lastObject];


             ACAccountCredential *facebookCredential = [self.facebookAccount credential];
             NSString *accessToken = [facebookCredential oauthToken];
             NSLog(@"Facebook Access Token: %@", accessToken);


             NSLog(@"facebook account =%@",self.facebookAccount);

             [self get];

             [self getFBFriends];

             isFacebookAvailable = 1;
         } else
         {
             //Fail gracefully...
             NSLog(@"error getting permission yupeeeeeee %@",e);
             sleep(10);
             NSLog(@"awake from sleep");
             isFacebookAvailable = 0;

         }
     }];
   }

-(void)get
{

    NSURL *requestURL = [NSURL URLWithString:@"https://graph.facebook.com/me"];

    SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook requestMethod:SLRequestMethodGET URL:requestURL parameters:nil];
    request.account = self.facebookAccount;

    [request performRequestWithHandler:^(NSData *data, NSHTTPURLResponse *response, NSError *error) {

        if(!error)
        {

            NSDictionary *list =[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];

            NSLog(@"Dictionary contains: %@", list );

            fbID = [NSString stringWithFormat:@"%@", [list objectForKey:@"id"]];
            globalFBID = fbID;

            gender = [NSString stringWithFormat:@"%@", [list objectForKey:@"gender"]];
            playerGender = [NSString stringWithFormat:@"%@", gender];
            NSLog(@"Gender : %@", playerGender);


            self.globalmailID   = [NSString stringWithFormat:@"%@",[list objectForKey:@"email"]];
            NSLog(@"global mail ID : %@",globalmailID);

              fbname = [NSString stringWithFormat:@"%@",[list objectForKey:@"name"]];
            NSLog(@"faceboooookkkk name %@",fbname);

            if([list objectForKey:@"error"]!=nil)
            {
                [self attemptRenewCredentials];
            }
            dispatch_async(dispatch_get_main_queue(),^{

            });
        }
        else
        {
            //handle error gracefully
            NSLog(@"error from get%@",error);
            //attempt to revalidate credentials
        }

    }];

    self.accountStore = [[ACAccountStore alloc]init];
    ACAccountType *FBaccountType= [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

    NSString *key = @"451805654875339";
    NSDictionary *dictFB = [NSDictionary dictionaryWithObjectsAndKeys:key,ACFacebookAppIdKey,@[@"friends_videos"],ACFacebookPermissionsKey, nil];

我终于明白了，显然您无法在URL内追加。 您需要在SLRequest内部的参数中传递字段

NSURL *requestURL = [NSURL URLWithString:@"https://graph.facebook.com/me/friends"];

NSDictionary *param=[NSDictionary dictionaryWithObjectsAndKeys:@"picture,id,name,installed",@"fields", nil];

SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                        requestMethod:SLRequestMethodGET
                                                  URL:requestURL
                                           parameters:param];
