StringInChain

An convenient and fast approach to create AttributedString.

StringInChain give you a far more clean way to create attributed string.

The Old Way

With the old way, create am attributed string is dirty and complex.

let baseString: NSString = "String In Chain"
var attrText = NSMutableAttributedString(string: baseString as String)
attrText.addAttribute(NSForegroundColorAttributeName, value: UIColor.blueColor(), range: baseString.rangeOfString("String"))
attrText.addAttribute(NSFontAttributeName, value: UIFont(name: "Avenir", size: 30.0)!, range: baseString.rangeOfString("String"))
attrText.addAttribute(NSUnderlineStyleAttributeName, value: 1, range: baseString.rangeOfString("In"))
attrText.addAttribute(NSUnderlineColorAttributeName, value: UIColor.yellowColor(), range: baseString.rangeOfString("In"))
attrText.addAttribute(NSStrokeWidthAttributeName, value: 1, range: baseString.rangeOfString("Chain"))
attrText.addAttribute(NSStrokeColorAttributeName, value: UIColor.blackColor(), range: baseString.rangeOfString("Chain"))
label.attributedText = attrText

With StringInChain

let baseString = "String In Chain"
var attrText = baseString.chain { (string) -> Void in
    string.match("String").withColor(UIColor.blueColor()).withFont(UIFont(name: "Avenir", size: 30.0)!)
    string.match("In").underline(1, andColor: UIColor.yellowColor())
    string.match("Chain").withStroke(1, andColor: UIColor.blackColor())
}
label.attributedText = attrText.attrString

Instead of match(text: String) (this way you can find only first occurance of string), you can use:

match(from: Int, to:Int)

Example:

string.match(from: 7, to: 10).withColor(UIColor.blueColor()).withFont(UIFont(name: "Avenir", size: 30.0)!)

This way you can create AttributedString by match range from and to

If you want, there is also fast, inline way to make AttributedString

label.attributedText = "String In Chain".match("String").withColor(UIColor.blueColor()).withFont(UIFont(name: "Avenir", size: 30.0)!).attrString

Clean and Easy, don’t You think?
