I'm fairly new to Swift and having some trouble iterating through a list of images to animate them. I have all of them named, for instance "aquarium-x", with x being a number from 1-29, depending on how many images I have for the specific animation. This is the code that I have for that part

我对Swift相当新,并且在遍历图像列表时遇到一些麻烦来制作动画。我将所有这些命名为“aquarium-x”,其中x是1-29的数字,具体取决于我对特定动画的图像数量。这是我对该部分的代码

func checkAnimationImages() -> [AnyObject] {
    var i = 0
    var catGifArray = [UIImage]()
    var image = UIImage(named: "-\(i)")
    while (image != nil){
        catGifArray.append(image!)
        ++i
        image = UIImage(named: "-\(i)")
    }
   return catGifArray.map {
        return $0.CGImage as! AnyObject
    }
}

My problem is I can't figure out how to also incorporate an array of strings into the UIImage so I don't need to type all the names out.

我的问题是我无法弄清楚如何将一个字符串数组合并到UIImage中,所以我不需要输出所有的名字。

var catGifName:[String] = [
        "3d",
        "piano1",
        "aquarium",
        "bag",
        "bitey",
        "black",
        "blackcat"]

I tried to put the name of the array in the "-/(i)" portion but that gives back an error.

我试图将数组的名称放在“ - /(i)”部分,但这会给出错误。

2 个解决方案

func checkAnimationImages(fileNames: [String]) -> [AnyObject] {
for name in fileNames {
    var i = 0
    var catGifArray = [UIImage]()
    var image = UIImage(named: "\(name)-\(i)")
    while (image != nil){
        catGifArray.append(image!)
        ++i
        image = UIImage(named: "\(name)-\(i)")
    }
}
return catGifArray.map {
    return $0.CGImage as! AnyObject
}
}

self.checkAnimationImages(self.catGifNames)

var images = [UIImage]()
let catGifName = ["cat","piano","aquarium","bag"]
for name in catGifName {
    for i in 1...29 {
        if let image = UIImage(named:"\(name)-\(i)") {
            images.append(image)
        }
    }
}
