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

我已将视图添加为ChildViewcontroller，并且只想在ChildViewController中将其关闭，然后转到上一个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，我具有SaveButton，该按钮应关闭该视图并返回到ParentViewController（editVC）

我试过的是

 @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:-(

最佳答案

尝试：

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

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

另外，如果要在同一超级视图中删除另一个视图，则可以：

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