How to take my view as a picture osx - objective-c

Question

I want to take my NSView(With layers) as an image can I do so in OSX ?
in iOS I would do the following
-(UIImage*) makeImage//snapshot the view
{
UIGraphicsBeginImageContext(self.view.bounds.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return viewImage;
}
I tried this solution from 1 of the SO answers
[[NSImage alloc] initWithData:[view dataWithPDFInsideRect:[view bounds]]];
but it didn't work because I have layers in my NSView.
I started from converting UI to NS
and now I have warnings on every line :)
-(NSImage*) makeImage :(RMBlurredView*)view
{
UIGraphicsBeginImageContext(view.bounds.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
NSImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return viewImage;
}
I am not familiar with OSX can some 1 help me to convert this code to OSX ?

drawing to the image is tad different than in iOS:
you create a blank image, LOCK on to it, so all drawing goes to that graphics context
NSImage *image = [[NSImage alloc] initWithSize:self.view.bounds.size];
[image lockFocus];
you draw your layer same as on iOS
CGContextRef ctx = [NSGraphicsContext currentContext].graphicsPort;
[self.view.layer renderInContext:ctx];
unlock image
[image unlockFocus];
NOTE this is only if your view is layered. it doesn't work for non-layered views!
your view -as shown above- is layer backed so all's fine ;)
