ios - 通过 Xcode 8 中的按钮移动图像

Question

我正在尝试在 Xcode 8 中移动图片。我有它的代码，但按下按钮时图像不会移动。有人可以帮我解决图片不动的问题吗？

import UIKit

class Level2ViewController: UIViewController {


 var image = UIImage(named: "ballon.png")

     var imageView = UIImageView(image: "ballon")//initialize properly, this is just for reference



    @IBAction func buttonPressed(_ sender: UIButton) {

            self.imageView.frame.origin.x += 50

    }


    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


    /*
    // MARK: - Navigation

    // In a storyboard-based application, you will often want to do a little preparation before navigation
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        // Get the new view controller using segue.destinationViewController.
        // Pass the selected object to the new view controller.
    }
    */

}

从代码中删除按钮，然后右键单击按钮并单击“x”以删除与旧代码的连接。

现在重新添加按钮。我认为你的按钮设置错误。 当您右键单击按钮时，查看发送事件是什么。 应该这样设置。
