scenekit - Cannot create a Screenshot of a SCNView

Question

Is it possible to get a screenshot of an SCNView? I'm trying with the below code, but it always comes out white...

NSRect bounds = [window.contentView bounds];
NSImage *screenshot = [[NSImage alloc] initWithData:[window.contentView dataWithPDFInsideRect:bounds]];

It works fine when the view is a standard NSView...

Answer 1

In OS X v10.10 and iOS 8, SCNView adds a snapshot method, so you can get an NSImage (or UIImage) out of it much more easily.
