UINavigationController將視圖控制器添加到導航堆棧的方法？

Question

UINavigationController的哪個方法用於在swift中將視圖控制器添加到導航堆棧？

Answer 1

通常情況下，使用下面的方法來推動UIViewController到UINavigationController的導航堆棧

pushViewController(_ viewController: UIViewController, animated: Bool) 

這是通過以下方式你CustomViewController類中實現：

let someVC: CustomViewController = CustomViewController() // this is one way of initializing it 
self.navigationController?.pushViewController(someVC, animated: true) 

以下是另一個方法可用於將UIViewController添加到UINavigationController堆棧

setViewControllers(_ viewControllers: [UIViewController], animated: Bool)
