Hi all-
I've got a category on NSColor to return a CGColor value. Source looks like
this:
- (CGColorRef)CGColor
{
NSColor *colorRGB = [self
colorUsingColorSpaceName:NSCalibratedRGBColorSpace];
CGFloat components[4];
[colorRGB getRed:&components[0] green:&components[1] blue:&components[2]
alpha:&components[3]];
CGColorSpaceRef theColorSpace =
CGColorSpaceCreateWithName(kCGColorSpaceGenericRGB);
CGColorRef theColor = CGColorCreate(theColorSpace, components);
CGColorSpaceRelease(theColorSpace);
return theColor;
}
My issue is with the final line: the CGColor has a retain count of 1, as it was
made with a "Create" function. Following Cocoa convention, I'd want to cast
the return value and autorelease it, but the autorelease call is not allowed
under ARC. Xcode is doing its best to help me figure out how to return the
value, but the only thing I can get it to not squeak about is this:
return (__bridge_retained CGColorRef)(__bridge_transfer id)theColor;
which does not seem reasonable to me. Can anyone suggest the proper syntax to
return an "autoreleased" CGColorRef from this function?
Thanks!
John
