当用户单击按钮时，如何在几秒钟内更改图像，然后在swift中恢复到原始图像？

您好，我是新的编码与Swift，我也是相当新的Stackoverflow。我如何制作一个按钮，改变图像大约5秒钟，然后在用户点击按钮时返回到原始图像

我试过使用这个代码

       dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (Int64)(5 * NSEC_PER_SEC)), dispatch_get_main_queue(), {
           gauntletImage.image = UIImage(named: gauntlet["gauntlet2"]) //change back to the old image after 5 sec
       });

但我一直有以下两个错误：

无法将“Int”类型的值转换为预期的参数类型“dispatch\u time\t”（也称为“UInt64”）

及

“dispatch\u get\u main\u queue（）的用法不明确”

这是我正在使用的更多代码

@IBOutlet weak var gauntletImage: UIImageView!

    let gauntlet = ["gauntlet1", "gauntlet2", "gauntlet3", "gauntlet4", "gauntlet5", "gauntlet6",]


    @IBAction func stonePressed(_ sender: UIButton) {
        print(sender.tag)

        gauntletImage.image = UIImage(named: gauntlet[sender.tag - 1]) //change to the new image

        dispatch_after(dispatch_time(dispatch_time_t(DISPATCH_TIME_NOW), (Int64)(5 * NSEC_PER_SEC)), dispatch_get_main_queue(), {
            gauntletImage.image = UIImage(named: gauntlet["gauntlet2"]) //change back to the old image after 5 sec
        });
    }

你可以试试

@IBAction func stonePressed(_ sender: UIButton) { 
    // store old image assuming it has an initial image in storyboard
    let oldImg = gauntletImage.image!
    // set new image
    gauntletImage.image = UIImage(named: gauntlet[sender.tag - 1])  
    // wait 5 seconds 
    DispatchQueue.main.asyncAfter(deadline: .now() + 5 ) { 
        // set back old image
        self.gauntletImage.image = oldImg   
   }   

}

用户可以多次单击它，这样您就可以

sender.isEnabled = false

在dispatch after块中存储旧图像并将其设置回

true

时，您可以尝试

@IBAction func stonePressed(_ sender: UIButton) { 
    // store old image assuming it has an initial image in storyboard
    let oldImg = gauntletImage.image!
    // set new image
    gauntletImage.image = UIImage(named: gauntlet[sender.tag - 1])  
    // wait 5 seconds 
    DispatchQueue.main.asyncAfter(deadline: .now() + 5 ) { 
        // set back old image
        self.gauntletImage.image = oldImg   
   }   

}

用户可以多次单击它，这样您就可以

sender.isEnabled = false

---

存储旧图像并将其设置回调度后块内的

true

时
