如何在ios上設置FBLoginview的用戶讀取權限？

Question

我使用Facebook SDK和FBLoginView登錄Facebook，我得到了一個基本的用戶信息，但我需要更多的權限，如email,birthday。 如何添加權限？

Answer 1

FBLoginView *loginView = [[FBLoginView alloc] init]; 
loginView.readPermissions = @[@"email", @"user_likes"]; 

Answer 2

試試這個：

- (BOOL)openSessionWithAllowLoginUI:(BOOL)allowLoginUI { 

      NSArray *permissions = [[NSArray alloc] initWithObjects: @"email", nil]; 
       return [FBSession openActiveSessionWithReadPermissions:permissions allowLoginUI:allowLoginUI completionHandler:^(FBSession *session, FBSessionState state, NSError *error) { 
      [self sessionStateChanged:session state:state error:error]; 
       }]; 
    } 

調用此方法與YES，可以給不同的權限一樣

[[NSArray arrayWithObjects: 
          @"email", 
          @"user_birthday", 
          @"user_likes", 
          @"user_location", 
          @"user_photos", 
          @"read_stream", 
          @"publish_stream", 
          @"publish_actions", 
          @"status_update", 
          @"user_about_me", 
          @"read_friendlists", 
          @"friends_about_me", 
          @"friends_birthday", 
          @"friends_photos", 
          nil] retain];
