What is the UIGraphicsGetCurrentContext() equivalent for OS X?

Question

Title says it all.

I'm trying to figure out what the UIGraphicsGetCurrentContext() equivalent is for OS X.

Answer 1

Just for completeness, in Swift 4, the syntax is:

NSGraphicsContext.current?.cgContext

Answer 2

[NSGraphicsContext currentContext].CGContext.

(The -CGContext property is available in 10.10 and later; in earlier versions, you can use graphicsPort.)

Answer 3

For Swift: NSGraphicsContext.currentContext()?.CGContext
