Make first letter Bold - ios swift

问题

I am creating an application for Dutch and English language. So I add my string values to Localizable.strings file. Now I want to change only one items first letter should be capitalized. For example, my string like this

A. I am in.

B. I am out.

I want to capitalize A. and B. and C. etc. I want to do it programmatically.

How can I do this in ios using swift as a language.

回答1:

Try to add attribute to string i.e.

yourString.addAttribute(NSFontAttributeName, value: UIFont( name: "HelveticaNeue-Bold", size: 18.0)!, range: NSRange( location:2, length:4))

here you can decide location for word in string.Hope it will work :) Also please refer following link :- http://makeapppie.com/2014/10/20/swift-swift-using-attributed-strings-in-swift/

Try like this:

extension UILabel {
    func setFirstLetterCapitalizedBold() {
        if text?.characters.count > 0 {
            let attText = NSMutableAttributedString(string: String(text!.characters.first!).uppercaseString + String(text!.characters.dropFirst()))
            attText.setAttributes([NSFontAttributeName:UIFont.boldSystemFontOfSize(font.pointSize)], range: NSRange(location: 0, length: 1))
            attributedText = attText
        }
    }
}

let myLabel = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 50))
myLabel.font = UIFont(name: "Arial Black", size: 20)

myLabel.text = "a. I am "
myLabel.setFirstLetterCapitalizedBold()

myLabel
