NSAttributedString on UIButton

Question

let strNo = "2222555" // size 18, this should be bold

let remainingStr = "Call to" + "\(strNo)" + "Number"

Now, in my UIButton, say button, How to set this title "Call to 2222555 number" And i need to change the size according to device, so I have to do it by coding.

Update

I need like following image.

And need to change the size of the title by coding. Above screenshot is from iPhone 7, In iPhone 5 it become bigger and in iPad it become smaller, so i have to set the size of the title according to requirement.

Any help will be appreciable.

Thanks

No, this is not my answer, the number 2222555 should be bold and the remaining string should be normal, and I need to do it by coding, it can be possible through property section in xcode storyboard, but it will be fixed for every device, thats why i need to do it by coding, so that i can change it according to device, and attributed text font are not simply changed by doing that. — Abhishek Mitra, Aug 01 '17 at 07:27

I found the Answer by struggling few days. And it is quite easy.

guard
            let font1 = UIFont(name: "HelveticaNeue-Bold", size: 22),
            let font2 = UIFont(name: "HelveticaNeue-Medium", size: 22)  else { return }

        let dict1:[String:Any] = [
            //            NSUnderlineStyleAttributeName:NSUnderlineStyle.styleSingle.rawValue,
            NSFontAttributeName:font2,
            NSParagraphStyleAttributeName:style,
            NSForegroundColorAttributeName: UIColor.white
        ]

        let dict2:[String:Any] = [
            //            NSUnderlineStyleAttributeName:NSUnderlineStyle.styleNone.rawValue,
            NSFontAttributeName:font1,
            NSParagraphStyleAttributeName:style,
            NSForegroundColorAttributeName: UIColor.white,
            //            NSFontAttributeName: UIFont.boldSystemFont(ofSize: 20)
        ]

        let dict3:[String:Any] = [
            //            NSUnderlineStyleAttributeName:NSUnderlineStyle.styleNone.rawValue,
            NSFontAttributeName:font2,
            NSParagraphStyleAttributeName:style,
            NSForegroundColorAttributeName: UIColor.white
        ]

        let dict4:[String:Any] = [
            //            NSUnderlineStyleAttributeName:NSUnderlineStyle.styleNone.rawValue,
            NSFontAttributeName:font1,
            NSParagraphStyleAttributeName:style,
            NSForegroundColorAttributeName: UIColor.white
        ]

        let attString = NSMutableAttributedString()
        attString.append(NSAttributedString(string: "Call to", attributes: dict1))
        attString.append(NSAttributedString(string: " 2222555 ", attributes: dict2))
        attString.append(NSAttributedString(string: " To Book Your Skip ", attributes: dict3))
        attString.append(NSAttributedString(string: "NOW", attributes: dict4))

        btnCall.setAttributedTitle(attString, for: .normal)

And its Working perfectly as expected.
