Converting UIColor to CGColor in swift

Question

This is the Obj-C code:

CGContextSetStrokeColorWithColor(context, [[UIColor lightGrayColor] CGColor]);

How do I write it in swift.

Solution 1

// Original answer.
var newColor = UIColor.lightGrayColor().CGColor

// Swift 3 version
var newColor = UIColor.lightGray.cgColor

Solution 2

Oddly enough, as Swift has evolved to 3.0 the answer has evolved as well. I ran across this while converting some Objective C code to Swift. I hope this helps someone! :-) Here is what it is today:

context.setStrokeColor(UIColor.lightGray.cgColor)

And it's funny, this "light gray" answer is actually helping me debug some code too! Thank iou!

Solution 3

Swift 4+ version

UIColor.lightGray.cgColor

@idmean I don't think an explanation is needed. The question is basically asking for a single line of code. "Give me this Obj-C line in Swift". What kind of explanation are you expecting? This is all that's required to answer this kind of question

That's why the question has 3 downvotes. Just because the OP doesn't know how to properly ask a question in english (perhaps there's a language barrier) doesn't mean he or she doesn't deserve an answer to the question. If no one could understand what was being asked, that's different. But it's easy to interpret what is being asked
