Question

Suppose I’m using CGColorSpaceRef. I’m wondering if there is a difference between releasing the CGColorSpaceRef by calling CFRelease versus using CGColorSpaceRelease?

i.e., a difference between this:

CGColorSpaceRef colorspace = CGColorSpaceCreateDeviceRGB();

// do stuff

CFRelease(colorspace);

versus doing:

CGColorSpaceRef colorspace = CGColorSpaceCreateDeviceRGB();

// do stuff

CGColorSpaceRelease(colorspace);

From the CGColorSpace Reference:

This function is equivalent to CFRelease, except that it does not cause an error if the cs parameter is NULL.
