UINavigationController回到了多个步骤

Question

是否可以在UINavigationController中弹出多个viewcontroller？假设我想退两步.

Answer 1

是的,你可以做类似的事情

//Your navigation controller
UINavigationController *nav;

//Get the view controller that is 2 step behind
UIViewController *controller = [nav.viewControllers objectAtIndex:nav.viewControllers.count - 2];

//Go to that controller
[nav popToViewController:controller animated:YES];
