FBGrah api电话无法加载Facebook的登录页面&这是我在屏幕上看到的错误消息:
下面是我用来创建FBGraph Objetc的代码:
NSString *client_id = @"XXXXXXXXXXXXXXX";
fbGraph = [[FbGraph alloc] initWithFbClientID:client_id];
[fbGraph authenticateUserWithCallbackObject:self andSelector:@selector(fbGraphCallback) andExtendedPermissions:@"user_photos,user_videos,publish_stream,offline_access" andSuperView:self.view];
建议我如何解决这个问题。
