I have a NSAttributedString to which I am adding a NSTextAttachment. The image is 50w by 50h but I\'d like it to scale down to reflect the line height of the attributed stri

Swift4 if you want a attributed string along with the image or a icon

here you can do something like this.

func AttributedTextwithImgaeSuffixAndPrefix(AttributeImage1 : UIImage , AttributedText : String ,AttributeImage2 : UIImage,  LabelBound : UILabel) -> NSMutableAttributedString
{
    let fullString = NSMutableAttributedString(string: "  ")
    let image1Attachment = NSTextAttachment()
    image1Attachment.bounds = CGRect(x: 0, y: ((LabelBound.font.capHeight) - AttributeImage1.size.height).rounded() / 2, width: AttributeImage1.size.width, height: AttributeImage1.size.height)
    image1Attachment.image = AttributeImage1
    let image1String = NSAttributedString(attachment: image1Attachment)
    let image2Attachment = NSTextAttachment()
    image2Attachment.bounds = CGRect(x: 0, y: ((LabelBound.font.capHeight) - AttributeImage2.size.height).rounded() / 2, width: AttributeImage2.size.width, height: AttributeImage2.size.height)
    image2Attachment.image = AttributeImage2
    let image2String = NSAttributedString(attachment: image2Attachment)
    fullString.append(image1String)
    fullString.append(NSAttributedString(string: AttributedText))
    fullString.append(image2String)
    return fullString
}

you can use this code as mentioned below:

        self.lblMid.attributedText = AttributedTextwithImgaeSuffixAndPrefix(AttributeImage1: #imageLiteral(resourceName: "Left") , AttributedText: "  Payment Details  ", AttributeImage2: #imageLiteral(resourceName: "RIght") , LabelBound: self.lblMid)

here you can add images you can replace it with your own:

Left Image

Right Image

Out put will be like this
