How to do the flip animation between two UIViewControllers while clicking info button?
问题 I have a login page named "LoginViewController". I have an info button in this page. If I click on it, I want to show some information about my application. Also I want to present that information page using flip animation. The code for creating info button is, infoButton = [UIButton buttonWithType:UIButtonTypeInfoLight]; infoButton.frame = CGRectMake(285, 425, 30, 30); infoButton.backgroundColor = [UIColor clearColor]; [infoButton addTarget:self action:@selector(displayInfoView)
