In your cell, you can cancel the image load if it's going to get re-used. In your UITableViewCell subclass add the following:

-(void)prepareForReuse {
    [super prepareForReuse];
    [self.imageView cancelCurrentImageLoad]; // UIImageView for whatever image you need to cancel the loading for
}

Be sure to #import "UIImageView+WebCache.h" as well.

Though your app shouldn't be crashing, but I cannot help you without seeing some code, since it's not possible to pinpoint the cause of the crash from your description above.

The code I provided above should solve it, did you try it? I think your crash is related to something different. What is the crash description? – runmad Apr 26 '14 at 15:11

SWIFT 4.0

self.imageView.sd_cancelCurrentImageLoad()

In case you are using SDWebImage Activity Indicator and wants to remove that as well

self.imageView.sd_removeActivityIndicator()

`sd_removeActivityIndicator()` was removed in SDWebImage 5.0. Instead, you can use `self.imageView.sd_imageIndicator?.stopAnimatingIndicator()`. – Manabu Nakazawa Dec 11 '19 at 06:58

    for (SDWebImageDownloader *downloader in downloaders) {
    [downloader cancel];
    }

Put this line of code when your SDWebImage is already loaded:

[self.imageView cancelCurrentImageLoad];
