Question

Let’s say I have this piece of code:

CGColorSpaceRef colorSpaceRGB = CGColorSpaceCreateDeviceRGB();

CGContextSetStrokeColorSpace(context, colorSpaceRGB);
CGContextSetFillColorSpace(context, colorSpaceRGB);

After that I do some drawing. When I’m done,
do I need to manually release colorSpaceRGB if I’m using ARC? Like this:

CGColorSpaceRelease(colorSpaceRGB);

Or I don’t need to do anything?

Thanks 🙂

Yes. According to Apple’s doc: Because CGColorSpaceRelease function is equivalent to CFRelease, except that it does not cause an error if the cs parameter is NULL.
And if you create, copy, or explicitly retain a Core Foundation object, you are responsible for releasing it when you no longer need it (see Memory Management Programming Guide for Core Foundation).
