通过使用 facebook 进行身份验证后
FBSessionLoginBehavior behavior = FBSessionLoginBehaviorForcingWebView;
appDelegate.session = [[FBSession alloc] init];
[appDelegate.session openWithBehavior:behavior
completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
NSLog(@"session is %d",session.state);
[self dismissViewControllerAnimated:YES completion:nil];
}
];
我总是得到
session is 513
问题 :
what is the meaning of 513
请协助我解决这个问题。谢谢
