在iOS中播放准备好的动画 [英] Playing prepared animation in iOS

问题描述

我们有由设计公司制作的动画（在700x700 px，透明背景下，大约需要6-7秒的时间）。
我需要在iOS应用的开头展示这些动画。
>
在应用程序中轻松使用它们的最佳方法/格式是什么？
我不想处理动画细节，因为它们都已经由设计师准备了。

We have animations (approx. 6-7 seconds in 700x700 px, in transparent background) which are prepared by a design company.
I need to show these as an introduction in the beginning of our iOS app.

What is the best way/format to use them easily in the app?
I don't want to deal with animation details because they are all prepared by designers already.

到目前为止，我们已经使用 UIView 的 animationImages 功能尝试了png序列，但是这种方法不是内存友好。

We tried png sequences with UIView's animationImages feature so far, but this approach wasn't memory friendly.

您有什么建议？

推荐答案

尝试这种简单的方法：

let timer = Timer()

@IBOutlet weak var imageView: UIImageView!
override func viewDidLoad() {
    super.viewDidLoad()
    // I am using tiff image file  for animation.You can use png or jpg both will works...
    var imagesNames =  ["1.tiff","2.tiff","3.tiff","4.tiff","5.tiff","6.tiff","7.tiff","8.tiff","9.tiff","10.tiff","11.tiff","12.tiff","13.tiff","14.tiff","15.tiff"]

        var images = [UIImage]()

        for i in 0..<imagesNames.count{
            images.append(UIImage(named: imagesNames[i])!)
        }

        imageView.animationImages = images
        imageView.animationDuration = 2
        imageView.startAnimating()

    Timer.scheduledTimer(timeInterval: 4.0, target: self, selector: #selector(timeToMoveOn), userInfo: nil, repeats: true)
    }

注意：：如果您不想重复动画。在计时器功能中，将 repeat （重复）设置为 false

Note: If you dont want the animation to be repeat.In timer function set repeat to false

     func timeToMoveOn() {    
     //Do you stuff here.After animation finished
        print("It Workes")
     }

     //To hide status bar.If you want to hide statusBar.
     override var prefersStatusBarHidden: Bool {
     return true
     }
