ios - 英雄过渡无效

Question

我正在使用 the Hero library在 View Controller 之间进行转换。

第一个 View Controller :

class ViewController: UIViewController {
    @IBOutlet weak var tableView: UITableView!
    var people = [Person]()
    override func viewDidLoad() {
        super.viewDidLoad()
        hero.isEnabled = true
        hero.modalAnimationType = .push(direction: .right)

    }

    @IBAction func handleButton(){
        let view = self.storyboard?.instantiateViewController(withIdentifier: "secondVC") as! UIViewController
        present(view, animated: true, completion: nil)
    }
}

第二个 View Controller :

class Second: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        hero.isEnabled = true
        // Do any additional setup after loading the view.
    }
    @IBAction func handleBackButton(){
        hero.modalAnimationType = .push(direction: .left)
        hero.dismissViewController()
    }
}

它呈现没有任何动画的新 View 。当我关闭第二个 Controller 时，它将应用正确的动画。如何用动画呈现第二个 View ？

Answer 1

好的，找到解决方案了。在第一种情况下，我有:

@IBAction func handleButton() {
  let view = self.storyboard?.instantiateViewController(withIdentifier: "secondVC") as! UIViewController
  present(view, animated: true, completion: nil)
}

我必须在 View 上设置动画。

@IBAction func handleButton() {
  let view = self.storyboard?.instantiateViewController(withIdentifier: "secondVC") as! UIViewController
  view.hero.modalAnimationType = .push(direction: .right)
  present(view, animated: true, completion: nil)
}
