Question

I have this code for changing the image of a button:

- (void)mouseEntered:(NSEvent *)event {
    [self setImage:[NSImage imageNamed:@"FloatingButton_hover"]]; }

- (void)mouseExited:(NSEvent *)event {
    [self setImage:[NSImage imageNamed:@"FloatingButton_normal"]]; }

But i have @2x images of these 2 in my resources. How do i know if the Mac has retina, so i can [self setImage:[NSImage imageNamed:@"FloatingButton_normal@2x"]]? Or is there any other way?
Thanks

You don’t have to do that. Just put your @2x versions in the same folder and Cocoa will take care of the rest. You can test if it’s actually working by going into HiDPI mode.
