I have an array of images in my codes that are [UIImage] but I want to convert them to base64 - I couldn't ! - I found similar questions but when I used their answers I received Fatal Error
for i in 0...tinyViewController.imageUpload.count - 1 {
print(i)
let imageData = UIImageJPEGRepresentation(tinyViewController.imageUpload[i] , 1)
let base64String = (imageData! as Data).base64EncodedString(options: NSData.Base64EncodingOptions(rawValue: 0))
print(base64String)
}
Try this function to convert each UIImage to base64 String. I used it in my project. It works perfect for me.
func base64(from image: UIImage) -> String? {
let imageData = UIImagePNGRepresentation(image)
if let imageString = imageData?.base64EncodedString(options: .endLineWithLineFeed) {
return imageString
}
return nil
}
So, do this:
for i in 0...tinyViewController.imageUpload.count - 1 {
print(i)
print(base64(from: tinyViewController.imageUpload[i]))
}
