How can I center an image on a textView who is attached to a NSTextAttachment type? - swift

Question

I have a textView (programmatically) and I inserted an image appended to a NSTextAttachment and want it to be aligned to the center of the text view... but I haven't found any solutions yet...I was wondering if that task is possible to be done via code only...
let image = ResizeImage(image: UIImage(named: "logo")!, targetSize: size)
let image1Attachment = NSTextAttachment()
image1Attachment.image = image
let image1Attachments = NSAttributedString(attachment: image1Attachment)
My best approach to the solution on trying to achieve this was this code :
let image = ResizeImage(image: UIImage(named: "telepaint1")!,
targetSize: size)
//let textAttachment = NSTextAttachment()
let textAttachment = NSTextAttachment()
//let imageStyle = NSMutableParagraphStyle()
let imageStyle = NSMutableParagraphStyle()
//imageStyle.alignment = .center
imageStyle.alignment = .center
//textAttachment.image = image
textAttachment.image = image
let imageText = NSAttributedString(attachment:
textAttachment).mutableCopy() as! NSMutableAttributedString
//attempt to center image...
let attributedStringToAppend: NSMutableAttributedString =
NSMutableAttributedString(attributedString:
NSAttributedString(string: "\n\n"))
//attributedStringToAppend.addAttributes(attr, range: range)
let combination2: NSMutableAttributedString =
NSMutableAttributedString(attributedString:
NSAttributedString(string: "\n\n"))
combination2.append(lineBreak)
// combination2.addAttribute(attr, range: NSRange(location: 0,
length: length))
combination2.append(imageText)
//this text will display the "Walktrough" text on image
combination2.append(attributedText)
tv.attributedText = combination2

Answer(worked for me!):
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = .center
attributedText.addAttribute(NSAttributedString.Key.paragraphStyle, value: paragraphStyle, range: NSRange(location: 0, length: length))
let size = CGSize(width: 100, height: 100)
//Here is an attempt to resize image and center it...
let image = ResizeImage(image: UIImage(named: "logo")!.withRenderingMode(.alwaysTemplate), targetSize: size)
let textAttachment = NSTextAttachment()
let imageStyle = NSMutableParagraphStyle()
imageStyle.alignment = .center
textAttachment.image = image
let imageText = NSAttributedString(attachment: textAttachment).mutableCopy() as! NSMutableAttributedString
let length2 = imageText.length
imageText.addAttribute(NSAttributedString.Key.paragraphStyle, value: imageStyle, range: NSRange(location: 0, length: length2))
