我有 3 个视图控制器HomePageController
、ChangePasswordViewController
、PasswordChangedDoneController
在主页更改密码按钮操作中,我将屏幕推入ChangePasswordViewController
。
let vc = self.storyboard?.instantiateViewController(withIdentifier: "ChangePasswordViewController")as! ChangePasswordViewController
self.navigationController?.pushViewController(vc, animated: true)
现在我正在呈现屏幕ChangePasswordViewController
PasswordChangedDoneController
.
let vc = self.storyboard?.instantiateViewController(withIdentifier: "PasswordChangedController")as! PasswordChangedDoneController
self.navigationController?.present(vc, animated: true, completion: nil)
现在我想在PasswordChangedDoneController
中使用Gotit按钮操作去HomePageController
.在这里,我想通过单个操作一次删除推送和呈现。
您可以使用
此函数弹出给定控制器的类类型
extension UIViewController {
/// like UIViewController.popToRoot
public func popToRoot() {
guard let navigationController = navigationController else { return dismiss(animated: true) }
navigationController.popToRootViewController(animated: true)
}
/// like UIViewController.popTo(:)
public func popTo(_ vc: UIViewController.Type, _ orPopToRoot: Bool = true) {
guard let navigationController = navigationController else { return popToRoot() }
let list = navigationController.viewControllers.reversed().filter { return $0.isKind(of: vc) }
guard let c = list.first else {
if orPopToRoot { self.popToRoot() }
else { self.popSelf(animated: true) }
return
}
navigationController.popToViewController(c, animated: true)
}
/// like UIViewController.popViewController
///
/// - Note: if can't found navigationController. will 'dismiss(animated:completion:)'
public func popSelf(animated: Bool) {
guard let navigationController = navigationController else { return dismissSelf(animated: animated) }
navigationController.popViewController(animated: animated)
}
/// like UIViewController.dismiss
public func dismissSelf(animated: Bool, completion: (() -> Void)? = nil) {
dismiss(animated: animated, completion: completion)
}
}
