Ios 未在OAuth.io中调用委托

未调用OAuth.io委托方法..有什么想法吗

ViewController.h

---

接收OAuthResponse时可能存在一些问题：-

//在身份验证失败的情况下处理错误

- (void)didFailWithOAuthIOError:(NSError *)error{
    NSLog(@"Failure");
}

检查此方法是否正在调用。如果这是调用，则表示委托方法没有任何问题

谢谢

 authModel = [[OAuthIOModal alloc] initWithKey:@"Yk7aY94Vskjj3b6yDy3tWkBEEXo" delegate:self];
[authModel showWithProvider:@"facebook"];

//On success, the didReceiveOAuthIOResponde delegate method is called:
- (void)didReceiveOAuthIOResponse:(OAuthIORequest *)request
{
// Here you can use the request object to make requests directly
// or store it for later use (e.g. when a button is pressed)
}

- (void)didFailWithOAuthIOError:(NSError *)error{
    NSLog(@"Failure");
}
