Get size of a UIImage (bytes length) not height and width

Question

I\'m trying to get the length of a UIImage. Not the width or height of the image, but the size of the data.

Answer 1

Example in Swift:

let img: UIImage? = UIImage(named: "yolo.png")
let imgData: NSData = UIImageJPEGRepresentation(img, 0)
println("Size of Image: \(imgData.length) bytes")
