ios - 在 ChildViewController 中关闭 ChildViewController 并转到上一个 ViewController

Question

我已添加一个 View 作为 ChildViewcontroller，并且我只想在 ChildViewController 中关闭它并转到上一个 ViewController

来自 ParentViewController 的代码

 @IBAction func click_monday(_ sender: Any) {
    let blurEffect = UIBlurEffect(style: .regular)
    let blurEffectView = UIVisualEffectView(effect: blurEffect)
    blurEffectView.frame = self.view.bounds
    blurEffectView.alpha = 0.8
    view.addSubview(blurEffectView)

    taskVC = self.storyboard?.instantiateViewController(withIdentifier: "Task") as! TaskVC
    taskVC.view.backgroundColor = .clear
    taskVC.modalPresentationStyle = .overCurrentContext

    taskVC.preferredContentSize = CGSize(width: 550.0, height: 400.0)
    self.view.addSubview(taskVC.view)
}

在 TaskVC 中，我有 SaveButton，它应该关闭该 View 并返回到 ParentViewController(editVC)

我尝试的是

 @IBAction func click_save(_ sender: Any) {


    let vc = self.storyboard?.instantiateViewController(withIdentifier: "edit") as! editVC
     self.navigationController?.pushViewController(vc, animated: false)

}

但它不起作用:-(

Answer 1

尝试:

 @IBAction func click_save(_ sender: Any) {
      self.view.removeFromSuperview()
      self.removeFromParentViewController()

      //self.navigationController?.popViewController(animated: true) //Add this if necessary
 }

此外，如果您想删除同一 super View 中的另一个 View ，您可以:

let blurView = self.view.superview?.viewWithTag(100)  //assume that blurView's tag is set before by: blurView.tag = 100 
blurView?.removeFromSuperview()
