Load image from folder inside project

Question

I'm making an app with the folder like image below:

As you can see in this picture, Stickers folder have 2 sub folder "1" and "2". In side them is bunch of icon and I wanna load it in a collection view with each sub folder is a package of different sticker. For more details, please see this picture:
So, how can I get it in my project folder? I've read about access document directory but seem like it not solve my problem.
Please help me. Thanks in advance.

Answer 1

Look at Filemanagers API. It offers all you need.

Example to get content at path:

let pathToDir1 = Bundle.main.resourcePath! + "/Stickers/1";
let fileManager = FileManager.default
let contentOfDir1 = try! fileManager.contentsOfDirectory(atPath: pathToDir1)

Example to iterate over:

let docsPath = Bundle.main.resourcePath!
let enumerator = fileManager.enumerator(atPath:docsPath)
let images = [UIImage]()
while let path = enumerator?.nextObject() as! String {
    let contentOfCurDir = try! fileManager.contentsOfDirectory(atPath: path)
    // do whatever you need.
}

For details see Apples documentation and sample code.

If you're looking to access an image within your project folder you simply need to use the image name. You don't need to define the whole path.

Objective-C

UIImage *img = [UIImage imageWithName:@"IMAGE_NAME"];

swift

var img = UIImage(named:"IMAGE_NAME")
