ios - 在 Swift 中制作 Gif 动画

Question

我一直在尝试在 Swift 中制作 GIF 动画，但它就是行不通。我想我找到了一个方法，但是有一个错误，请帮助。

代码如下:

@IBOutlet var imageView: UIImageView!
override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.
    // (Here is the error it states "Cannot assign a value of type '[UIImage?]' to a value of type '[UIImage]?'")
    imageView.animationImages = [

        UIImage(named: "logo1.jpg"),
        UIImage(named: "logo2.jpeg"),
        UIImage(named: "logo3.png")
    ]

    imageView.animationDuration = 3
    imageView.startAnimating()
}

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

就您代码中的问题而言，正如“Leo Dabus”已经指出的那样，您是否没有取消包装 UIImage 实例。通过以下修改尝试相同的代码。

imageView.animationImages = [

        UIImage(named: "logo1.jpg")!, //File Extension would not be required if .png
        UIImage(named: "logo2.jpeg")!,  //File Extension would not be required if .png
        UIImage(named: "logo3.png")!
    ]

    imageView.animationDuration = 3
    imageView.startAnimating()
