ios - 使用循环将属性添加到多个UIImageViews

我要添加动画的8个UImageView。我知道我可以制作八次动画，但是我可以使用一个循环-也许可以进行插值吗？

这是我的动画代码：

override func viewDidLoad() {
        super.viewDidLoad()

        self.dieImage0.animationImages = [
            UIImage(named: "dicey-die1")!,
            UIImage(named: "dicey-die2")!,
            UIImage(named: "dicey-die3")!,
            UIImage(named: "dicey-die4")!,
            UIImage(named: "dicey-die5")!,
            UIImage(named: "dicey-die6")!,
            UIImage(named: "dicey-die1")!,
            UIImage(named: "dicey-die2")!,
            UIImage(named: "dicey-die3")!,
            UIImage(named: "dicey-die4")!,
            UIImage(named: "dicey-die5")!,
            UIImage(named: "dicey-die6")!,
            UIImage(named: "dicey-die1")!,
            UIImage(named: "dicey-die2")!,
            UIImage(named: "dicey-die3")!,
            UIImage(named: "dicey-die4")!,
            UIImage(named: "dicey-die5")!,
            UIImage(named: "dicey-die6")!,
            UIImage(named: "dicey-die1")!,
            UIImage(named: "dicey-die2")!,
            UIImage(named: "dicey-die3")!,
            UIImage(named: "dicey-die4")!,
            UIImage(named: "dicey-die5")!,
            UIImage(named: "dicey-die6")!
        ]

        self.dieImage0.animationRepeatCount = 1
        self.dieImage0.animationDuration = 1.0


    }

并开始动画：

override func motionEnded(motion: UIEventSubtype, withEvent event: UIEvent) {

        self.dieImage0.startAnimating()  /* <======== */

        dieImage0.image = randomImages.randomDice();
        dieImage1.image = randomImages.randomDice();
        dieImage2.image = randomImages.randomDice();
        dieImage3.image = randomImages.randomDice();
        dieImage4.image = randomImages.randomDice();
        dieImage5.image = randomImages.randomDice();
        dieImage6.image = randomImages.randomDice();
        dieImage7.image = randomImages.randomDice();

        println("Motion Ended")
    }

我要为每个dieImage设置动画

编辑

我有几个要设置动画的UIImageView和@IBOutlet。

    @IBOutlet weak var dieImage0: UIImageView!
    @IBOutlet weak var dieImage1: UIImageView!
    @IBOutlet weak var dieImage2: UIImageView!
    @IBOutlet weak var dieImage3: UIImageView!
    @IBOutlet weak var dieImage4: UIImageView!
    @IBOutlet weak var dieImage5: UIImageView!
    @IBOutlet weak var dieImage6: UIImageView!
    @IBOutlet weak var dieImage7: UIImageView!

我如何遍历它们而不是为每个动画制作单独的动画，我已经有一个动画设置；往上看。

更新：

除了两个骰子已叛乱外，一切都按需要进行。第一个（dieImage0）始终落在1上，第二个（dieImage5）根本不执行任何操作！

更新2：

这是我用于动画的代码：

let dieImages = [dieImage0, dieImage1, dieImage2, dieImage3, dieImage4, dieImage5, dieImage6, dieImage7]

for die in dieImages {
    die.animationImages = [
        UIImage(named: "dicey-die2")!,
        UIImage(named: "dicey-die6")!,
        UIImage(named: "dicey-die1")!,
        UIImage(named: "dicey-die4")!,
        UIImage(named: "dicey-die3")!,
        UIImage(named: "dicey-die5")!,
        UIImage(named: "dicey-die3")!,
        UIImage(named: "dicey-die1")!,
        UIImage(named: "dicey-die6")!,
        UIImage(named: "dicey-die3")!,
        UIImage(named: "dicey-die5")!,
        UIImage(named: "dicey-die2")!,
        UIImage(named: "dicey-die4")!
    ]

    die.animationRepeatCount = 1
    die.animationDuration = 1.0
}

现在一切正常！

最佳答案

要创建animationImages，我可以这样做：

dieImage0.animationImages = (0..<4).reduce([UIImage]()) { images, _ in
    return images + (1..<7).map { UIImage(named: "dicey-die\($0)")! }
}

看起来animationImages由24个UIImages组成-4组6张图像，其中图像名称为"dicey-dieN"（（N被范围为(1..<7)的数字代替）。）

您可以创建一个包含六个图像的数组，如下所示：

let images = (1..<7).map { UIImage(named: "dicey-die\($0)")! }

您要这样做4次，然后将所有数组加在一起。您可以通过调用(0..<4).reduce([UIImage]()) { ... }

结果将是具有24个图像的单个阵列。

然后，按照@Chris Slowik的建议，创建一个dieImages数组，然后遍历它们以分配随机图像：

let dieImages = [dieImage0, dieImage1, dieImage2, dieImage3, dieImage4, dieImage5, dieImage6, dieImage7]

for dieImage in dieImages {
    dieImage.image = randomImages.randomDice()
    dieImage.startAnimating()
}

您的整个motionEnded方法应该看起来像这样：

override func motionEnded(motion: UIEventSubtype, withEvent event: UIEvent) {
    let dieImages = [dieImage0, dieImage1, dieImage2, dieImage3, dieImage4, dieImage5, dieImage6, dieImage7]

    for dieImage in dieImages {
        dieImage.image = randomImages.randomDice()
        dieImage.startAnimating()
    }

}

我认为您在dieImage0上遇到了问题，因为您在分配动画随机图像之前就开始播放动画。首先分配图像，然后开始动画处理。
