我想通过facebook sdk获取朋友列表，我这样做：
- (IBAction)buttonTouched:(id)sender
{
// If the session state is any of the two "open" states when the button is clicked
if (FBSession.activeSession.state == FBSessionStateOpen
|| FBSession.activeSession.state == FBSessionStateOpenTokenExtended) {
FBRequest* friendsRequest = [FBRequest requestForMyFriends];
[friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary* result,
NSError *error) {
NSLog(@"result:%@", result);
friend_list_array = [[NSMutableArray alloc] initWithArray:[result objectForKey:@"data"]];
FacebookChallengeViewController *facebook_V = [[FacebookChallengeViewController alloc] initWithNibName:@"FacebookChallengeViewController" bundle:nil withArray:friend_list_array];
[facebook_V setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];
[facebook_V setModalPresentationStyle:UIModalPresentationFormSheet];
[self presentViewController:facebook_V animated:YES completion:nil];
facebook_V.view.superview.center = CGPointMake(self.view.frame.size.width/2, self.view.frame.size.height/2);
}];
} else {
// Open a session showing the user the login UI
// You must ALWAYS ask for basic_info permissions when opening a session
[FBSession openActiveSessionWithReadPermissions:@[@"public_profile",@"user_friends"]
allowLoginUI:YES
completionHandler:
^(FBSession *session, FBSessionState state, NSError *error) {
// Retrieve the app delegate
AppDelegate* appDelegate =(AppDelegate*) [UIApplication sharedApplication].delegate;
// Call the app delegate's sessionStateChanged:state:error method to handle session state changes
[appDelegate sessionStateChanged:session state:state error:error];
}];
}
}
问题是“friend_list_array”只有接受te请求的人而不是我所有的朋友，问题是什么？
