App crash while downloading large images using SDWebImage

I'm using SDWebImage to download image async from server.Some images on server are of size( 1772x1476 pixels.)I'm showing these images on UICollectionView. I'm getting memory warning and app crashes after several run.Some times it happens when images downloaded first time and some time when i scroll the collection view up and down. Here is my code-

i am getting warning on my x code like below image

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{

    UICollectionViewCell *cell=[collectionView dequeueReusableCellWithReuseIdentifier:@"cellIdentifier" forIndexPath:indexPath];

[Mainimage sd_setImageWithURL:[NSURL URLWithString: Obj.imageYH] placeholderImage:[UIImage imageNamed:@""]];

   return cell;
}

enter image description here

You can use :

[SDImageCache sharedImageCache].config.shouldDecompressImages = NO; [[SDWebImageDownloader sharedDownloader] setShouldDecompressImages:NO];

In version 4.0-beta

If your app doesn't need to show a full sized image, then it's always a good practice to scale it down and then show. Here's an example of what to do.

SDWebImageManager *manager = [SDWebImageManager sharedManager];
[manager downloadWithURL:url delegate:self options:0 success:^(UIImage *image) 
{
    //Scale down the image here and then set to your view.
}

It should help you reduce the memory issues.
