How to release VM:ImageIO_GIF_Data using ARC?

Question

I use OLImage in the viewB's drawRect method to load a local gif image. I use a normal ViewA to push ViewB, and pop ViewB repeatedly. After about 20 times, my app crashed after received several memory warnings. I use instrument to monitor the memory usage, and you can see the result below.

My code to load gif is like:

@property (weak, nonatomic) IBOutlet OLImageView *gifImageView;


    if (!self.gifImageView.image) {
        self.gifImageView.image = [OLImage imageNamed:@"好.gif"];
        [self.gifImageView setUserInteractionEnabled:YES];
        [self.gifImageView addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)]];
    }

I'm use ARC, I think the gif data should be released by iOS when ViewB popped. Or at least when my app received memory warnings. Am I doing something wrong? OR this can be more general question that how to release VM memory in ARC?

It turns out it's maybe an issue of OLImage itself. I made a pull request for this issue. Check out the commit here if you are interested.
