动画uibutton应用图像快速 [英] animate uibutton applying images swift

问题描述

我想通过依次更改两个图像来应用动画效果。我已经应用了以下代码，但看不到动画效果。
我已经正确应用了IBOutlets。

I want to apply animation effect by changing two images on button turn by turn. I have applied following code but not able to see animation effect. I have applied IBOutlets properly.

    var image1:UIImage = UIImage(named: "img_mic_off")!
    var image2:UIImage = UIImage(named: "img_mic_on")!
    btnRecord.imageView?.animationImages = [image1,image1]
    btnRecord.imageView?.animationDuration = 1.0
    btnRecord.imageView!.startAnimating()

请帮助我解决为什么此给定代码无法使用的问题。谢谢。

Please help me to resolve issue that why it is not working with this given code. Thanks in advance.

推荐答案

检查一下我做了什么。图像正在改变。因此，我希望这是您真正需要的。

Check out what I've done. The images are changing. So I hope this is what you actually needed.

var image1:UIImage = UIImage(named: "img_mic_off")!
var image2:UIImage = UIImage(named: "img_mic_on")!
btn.setImage(image1, forState: UIControlState.Normal)
btn.imageView!.animationImages = [image1, image2]
btn.imageView!.animationDuration = 1.0
btn.imageView!.startAnimating()
