Maybe this a newbie question, but according to my instruments there is a leak there, but im releasing the imageRef. i cant figure it out. its a category function.
-(UIImage *)imageAtRect:(CGRect)rect
{
CGImageRef imageRef = CGImageCreateWithImageInRect([self CGImage], rect);
UIImage* subImage = [UIImage imageWithCGImage: imageRef];
CGImageRelease(imageRef);
return subImage;
}
It appears that you are leaking "subImage". imageWithCGImage: Creates and returns an image object representing the specified Quartz image. That means that the function creates a new image.
Make sure that you release the image later. That should get rid of the memory leak. Adding "autorelease" after "imageWithCGImage" will auto-magically get rid of the memory leak for you, depending on how you are using the returned value.
