我想快速编码和解码UIImage与AEXML中的值的字符串

Question

//To encode I found the following example. I don't know if it works yet

@IBAction func exitImageViewController(seque:UIStoryboardSegue){

    let imageController = seque.destination as! MyImageViewController
    let myView = imageController.imageView
    imageData  = UIImagePNGRepresentation((myView?.image!)!)
    imageString = imageData?.base64EncodedString()

// Is this swift code correct?

//I cannot find an example of decoding String back to UIImage

Answer 1

The code you posted looks fine. To encode back you can do this:

let data = Data(base64Encoded: imageString!)

let img = UIImage(data: data!)
