UIScreen.mainScreen.scale on NSScreen

I have a problem with CATextLayer cleaning. and with iOS the solution is:

textLayer.contentsScale = UIScreen.mainScreen.scale

But I can't found "scale" property on cocoa NSScreen

Note: Answer with Object-C or Swift are OK.

Solution

  • [[NSScreen mainScreen] backingScaleFactor] will give you the scaling factor for main display
