Question

I m trying to remove memory leaks. Below is my code.

currentTime = CFAbsoluteTimeGetCurrent();

CFTimeZoneRef currentTimeZone = CFTimeZoneCopyDefault();

todaysDate = CFAbsoluteTimeGetGregorianDate(currentTime, currentTimeZone);


[currentTimeZone release];
currentTimeZone = nil;

Warning:::/myclass.m:87: warning: invalid receiver type ‘CFTimeZoneRef’

how to release memory for typedef const struct?

Answer 1

With CFxxxCopyxxx you should use CFRelease.

CFRelease(currentTimeZone);

Edit:

There are CoreFoundation classes that are Toll-Free bridged and your original statement was not leaking but just needed a cast. I would still recommend using CFRelease since you were working directly with CoreFoundation.

[(NSTimeZone*)currentTimeZone release];
