如何替换NSMutableAttributedString中的字符串？

Question

I have this :

var attributedString = NSMutableAttributedString(string:"Welcome %@ to %@")

And I want to format this to add some other NSMutableAttributedString instead of %@

How can I achieve that?

Thanks

Answer 1

You can replace NSAttributeString with another NSAttributeString by following way. here in this example, you need to fine location of %@ symbol.

        let stringVariable = "Welcome @ location"

        var attributedString = NSMutableAttributedString(string:stringVariable)

        var attributedStringAnother = NSMutableAttributedString(string:"abc")


        attributedString.replaceCharactersInRange(NSRange(location: 8,length: 1), withAttributedString: attributedStringAnother)

        println(attributedString)

Here location: 8 is a location @ symbol.

Output is :

Welcome abc location{
}

Hope this help you.

Try this:

var attributedString = NSMutableAttributedString(string:"Welcome %@ to %@")

let result = attributedString.string.stringByReplacingOccurrencesOfString("%@", withString:"TEST")

var newAtrString = NSMutableAttributedString(string: result)

在Swift中，您可以这样操作：

var attributedString = NSMutableAttributedString(string:"Welcome \\(anotherAttributedString1) to \\(anotherAttributedString2)")
