如何在iOS 6中獲取Facebook好友？

Question

我想從我的應用程序發送邀請Facebook好友，就像在Instagram應用程序中一樣。

但我找不到任何好的教程。

我能夠獲得名稱&朋友的ID，但我無法獲取配置文件圖像，名稱等的URL。爲朋友。

我的代碼如下：

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

    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) 
     { 
      list =[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error]; 

      NSLog(@"Dictionary contains data: %@", list); 
      if([list objectForKey:@"error"]!=nil) 
      { 
       [self attemptRenewCredentials]; 
      } 
      dispatch_async(dispatch_get_main_queue(),^{ 
       nameLabel.text = [list objectForKey:@"username"]; 
      }); 
     } 
     else{ 
      //handle error gracefully 
      NSLog(@"error from get%@",error); 
      //attempt to revalidate credentials 
     } 

    }]; 

那麼，如何才能做到這一點？

Answer 1

你應該包括這在參數

[ NSMutableDictionary dictionaryWithObjectsAndKeys:@"picture,id,name,link,gender,last_name,first_name",@"fields",nil] 

Answer 2

這是代碼，它獲取好友列表

ACAccountStore *accountStore = [[ACAccountStore alloc] init]; 
__block ACAccount *facebookAccount = nil; 

ACAccountType *facebookAccountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook]; 

// Specify App ID and permissions 
NSDictionary *options = @{ 
ACFacebookAppIdKey: @"add_here_your_project_FB_ID", 
ACFacebookPermissionsKey: @[@"publish_stream", @"publish_actions",@"read_friendlists"], 
ACFacebookAudienceKey: ACFacebookAudienceFriends 
}; 

[accountStore requestAccessToAccountsWithType:facebookAccountType 
             options:options completion:^(BOOL granted, NSError *error) 
{ 
    if (granted) 
    { 
     NSArray *accounts = [accountStore accountsWithAccountType:facebookAccountType]; 

     facebookAccount = [accounts lastObject]; 
    } 
    else { 

     NSLog(@"error.localizedDescription======= %@", error.localizedDescription); 
    } 

}]; 

NSArray *accounts = [accountStore accountsWithAccountType:facebookAccountType]; 
facebookAccount = [accounts lastObject]; 

//NSString *acessToken = [NSString stringWithFormat:@"%@",facebookAccount.credential.oauthToken]; 
//NSDictionary *parameters = @{@"access_token": acessToken}; 

NSDictionary *param=[NSDictionary dictionaryWithObjectsAndKeys:@"picture,id,name,link,gender,last_name,first_name,username",@"fields", nil]; 

NSURL *feedURL = [NSURL URLWithString:@"https://graph.facebook.com/me/friends"]; 
SLRequest *feedRequest = [SLRequest 
          requestForServiceType:SLServiceTypeFacebook 
          requestMethod:SLRequestMethodGET 
          URL:feedURL 
          parameters:param]; 
feedRequest.account = facebookAccount; 
[feedRequest performRequestWithHandler:^(NSData *responseData, 
             NSHTTPURLResponse *urlResponse, NSError *error) 
{ 
    if(!error) 
    { 
     id json =[NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error]; 

     NSLog(@"Dictionary contains data: %@", json); 
     if([json objectForKey:@"error"]!=nil) 
     { 
      //[self attemptRenewCredentials]; 
     } 
     dispatch_async(dispatch_get_main_queue(),^{ 
      //nameLabel.text = [json objectForKey:@"username"]; 
     }); 
    } 
    else{ 
     //handle error gracefully 
     NSLog(@"error from get%@",error); 
     //attempt to revalidate credentials 
    } 
}]; 

我希望它可以幫助你。謝謝
