imageWithCGImage and memory

Question

If I use [UIImage imageWithCGImage:], passing in a CGImageRef, do I then release the CGImageRef or does UIImage take care of this itse

Answer 1

I have the same problem in XCode 3.2.1 on Snow Leopard. I have pretty much the same code as Jason.

I have looked at the iPhone sample code which uses imageWithCGImage and they always release the CGImageRef using CGImageRelease after a call to imageWithCGImage.

So, is this a bug in the simulator? I always get the malloc_error_break warning on the console when I use CGImageRelease.

Answer 2

"This method does not cache the image object."

So the UIImage take the ownership, and thus you should not release the CGImageRef.
