我正在使用社交框架检索脸书朋友列表。请看看我的以下代码，我是怎么做的，但它只给了我几个朋友，而不是全部。我检查了两个帐户，1个帐户有300个，它只返回我一个，一个帐户有50个，它只返回我3个。我也点击了下一页，但这是空的。
NSArray *accounts = [_accountStore accountsWithAccountType:FBaccountType];
//it will always be the last object with single sign on
_facebookAccount = [accounts lastObject];
ACAccountCredential *facebookCredential = [_facebookAccount credential];
NSString *accessToken = [facebookCredential oauthToken];
NSLog(@"Facebook Access Token: %@", accessToken);
_facebookAccount = [accounts lastObject];
_facebookToken = [facebookCredential oauthToken];
// _facebookToken = _facebookAccount.credential.oauthToken;
NSLog(@"facebook account =%@",_facebookAccount);
// Request friend list
NSDictionary *param=[NSDictionary dictionaryWithObjectsAndKeys:@"picture,id,name,link,gender,last_name,first_name",@"fields", nil];
SLRequest *friendsListRequest = [SLRequest requestForServiceType:SLServiceTypeFacebook
requestMethod:SLRequestMethodGET
URL: [[NSURL alloc] initWithString:@"https://graph.facebook.com/me/friends"] parameters:param];
friendsListRequest.account = _facebookAccount;
[friendsListRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
// Parse response JSON
NSError *jsonError = nil;
NSDictionary *data = [NSJSONSerialization JSONObjectWithData:responseData
options:NSJSONReadingAllowFragments
error:&jsonError];
NSMutableArray * fbFriends=[[NSMutableArray alloc] init];
for (NSDictionary *friend in data[@"data"]) {
NSLog(@"name: %@", friend[@"name"]);
[fbFriends addObject:friend];
}
[[NSUserDefaults standardUserDefaults] setObject:fbFriends forKey:@"FBFriends"];
}];
请建议我做错什么。提前致谢。
如果你的应用不是游戏，这可能是正常的行为。
