iphone - presentModalViewController 不调用任何方法

Question

在 presentModalViewController 中，使用 SSO 登录 Facebook 后不调用任何方法。

SignInViewController *signView=[[SignInViewController alloc]init];
signView.delegate=self;
[self.navigationController presentModalViewController:signView animated:YES];
[signView release];
- (void)cancelAction
{
      [self dismissModalViewControllerAnimated:YES];
}

cancelAction 方法正在调用但未关闭..

请帮我。

Answer 1

SignInViewController *signView=[[SignInViewController alloc]init];

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:signView];

[signView release];

[self presentModalViewController:navigationController animated:YES];

[navigationController release];

-(void)cancelAction
{

      [self dismissModalViewControllerAnimated:YES];
}

尝试实现这个...

希望这对你有用..
