How to show URL Images in TableView cell without stuck?

I have showed collections of URLImage in tableview cell. It is stuck while I am scrolling the cell. I have used third parties like SDWebImageManager and AFNetWorking. Never the less the cell has been stuck.

[imageVw setImageWithURL:[NSURL URLWithString:self.imgaeRecord.PreviewURl]placeholderImage:[UIImage imageNamed:@"default-thumbnail.jpg"]];

OR

NSURL *url =[NSURL URLWithString:[self.MoviesListImage objectAtIndex:indexPath.row]];

SDWebImageManager *manager = [SDWebImageManager sharedManager];
[manager downloadImageWithURL:url
                      options:0
                     progress:^(NSInteger receivedSize, NSInteger expectedSize) {
                        // progression tracking code
                     }
                    completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, BOOL finished, NSURL *imageURL) {
                    if (image) {
                        cell.recipeImageView.image = image;
                    }
                }];

I think your problem remains with the performance of the tableview when you have to do many image requests operations. So, in order to optimize the requests you should cancel the request that are being made when the cell leaves the visible area of the tableview. To accomplish that, in your custom cell implement - (void)prepareForReuse method and in there, assuming that you are using SDWebImage, do [imageView sd_cancelCurrentImageLoad]. Also, to download and assign the image to the ImageView you only need to do

[cell.imageView sd_setImageWithURL:url placeholderImage:[UIImage imageNamed:@"placeholder.png"]]

In your cellForRowAtIndexPath

NSURL *url =[NSURL URLWithString:[self.MoviesListImage objectAtIndex:indexPath.row]];

SDWebImageManager *manager = [SDWebImageManager sharedManager];
[manager downloadImageWithURL:url
                  options:0
                 progress:^(NSInteger receivedSize, NSInteger  expectedSize) {
                    // progression tracking code
           }
                completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, BOOL finished, NSURL *imageURL) {
                if (image) {
                   dispatch_async(dispatch_get_main_queue(), ^{
                   TableViewCellClass *updateCell = (id)[tableView cellForRowAtIndexPath:indexPath];
                   if (updateCell)
                     updateCell.yourImageView.image = image;
               });
           }
       }
}];
[task resume];

Try to use SDWebImage in this way inside cellForRowAtIndexPath method

NSURL *url =[NSURL URLWithString:[self.MoviesListImage objectAtIndex:indexPath.row]];
[cell.imageView sd_setImageWithURL:url
                placeholderImage:[UIImage imageNamed:@"placeholder.png"]
                completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
                 cell.recipeImageView.image = image
  }];
