如何在swift中将变量值放入另一个变量名中

Question

I am pretty new to Swift and I want to make a pretty big list of images called image1, image2, image3 and so on. The problem is that I need to make something like this:

var index = 1 ... image(index).image = ... index+=1

where index is a counter for my images ( image(index) to be image1, for example) but I don't know the right syntax for image(index).

Can someone let me know how?

Answer 1

try this

let imageArray = [UIImage]()

for i in 0..<limit {
    imageArray.append(UIImage(named: "image\(i)"))
}

Answer 2

If you want to init the image by name, image1jpg image2.jpg... image53.jpg you should do this:

let imageName = "image\\(index).jpg"

Then just create the image with the name

Answer 3

I guess you only need an array …

var images = [String]()
images.append("image1.jpg")
images.append("image2.jpg")
print(images.first) // "image1.jpg"
print(images[1]) // "image2.jpg"

Answer 4

Initially you need drag drop your all images into your Xcode project file with naming convention like image_1.png, image_2.png .... image_50.png

and write the code on your view controller

let imageArray:String = [String]()

for index in 1..<51 {
 imageArray.append(UIImage(named: "image_\(index)"))
 }

now you will get the an array of images name that reflect your stored images.
