Question

I have this block of code here which I use to load an image on a dispatch queue:

dispatch_async(dispatch_get_global_queue(0, 0), ^
{
    CGImageRef x = self.asset.defaultRepresentation.fullScreenImage;

    dispatch_async(dispatch_get_main_queue(), ^
    {
        [[self imageView] setImage: [UIImage imageWithCGImage: x]];
    });
});

The code seems to work a couple of times until eventually I get a bad access at this line [[self imageView] setImage: [UIImage imageWithCGImage: x]];. Anyone know what could be causing this?

Use

CGImageRef x = CGImageCreateCopy(self.asset.defaultRepresentation.fullScreenImage);

and

CGImageRelease(x) 

after you set that
