Swift UIImage as按钮

你可以使用 highlightedImage 和 isHighlighted 的属性 UIImageView . 你可以使用单 IBAction

在 viewDidLoad 方法:

yourImageView.image = UIImage(name:"RecordImage/TriggerImage")
yourImageView.highlightedImage = UIImage(name:"StopImage")

您也可以在界面生成器中设置这些图像。正如您在下图中所看到的,您需要为这两个设置图像 Image 和 Highlighted 属性。

在你的行动方法中:

yourImageView.isHighlighted = !yourImageView.isHighlighted

if yourImageView.isHighlighted
{
  //so now the UIImageView shows stop image that means we are in recording mode
  // do the actions that are to be done in recording mode like start recording updating other UI etc 
}
else
{
 //so now the UIImageView shows Record/Trigger image that means are in normal mode or not recording
  // do the actions that are to be done in normal mode like stop recording (if required )updating other UI etc 
}

你只需要一个 IBAction 同样,您可以通过操作内的以下代码检查图像:

if yourImageView.image == UIImage(named: "yourImageName") {
//perform some action here
} else {
//perform some action here 
}

步骤1-在ViewController类中声明一个属性以检查按钮的状态

如果选中=true//正在进行录制

如果为false//则停止录制

//declaration in ViewController class
    var isChecked = false

步骤2-添加按钮imageView并按如下方式分配其按钮操作

 @IBAction func BottomImageBtnAction(_ sender: UIButton) {
        isChecked = !isChecked
        if isChecked {
            //here şet image as stop
        }
        else {
            //here set image as Start
        }
    }
