How do you use NSAttributedString?

Question

Multiple colours in an NSString or NSMutableStrings are not possible. So I\'ve heard a little about the NSAttributedString which was introduced wit

Answer 1

I made a library that makes this a lot easier. Check out ZenCopy.

You can create Style objects, and/or set them to keys to reference later. Like this:

ZenCopy.manager.config.setStyles {
    return [
        "token": Style(
            color: .blueColor(), // optional
            // fontName: "Helvetica", // optional
            fontSize: 14 // optional
        )
    ]
}

Then, you can easily construct strings AND style them AND have params :)

label.attributedText = attributedString(
                                ["$0 ".style("token") "is dancing with ", "$1".style("token")], 
                          args: ["JP", "Brock"]
)

You can also style things easily with regex searches!

let atUserRegex = "(@[A-Za-z0-9_]*)"
mutableAttributedString.regexFind(atUserRegex, addStyle: "token")

This will style all words with '@' in front of it with the 'token' style. (e.g. @jpmcglone)

I need to still get it working w/ everything NSAttributedString has to offer, but I think fontName, fontSize and color cover the bulk of it. Expect lots of updates soon :)

I can help you get started with this if you need. Also looking for feedback, so if it makes your life easier, I'd say mission accomplished.
