ios - Icon downloader downloads images only when UITableViewcell is outside screen.iPhone -

I tried to search but no solution was found useful.

I am using the following code for the mouse to bring laziness while loading. The point is, icons are downloaded through lazy loading, but this is only seen once that the special cell is out of the screen and scrolls back in the screen.

I think that this is some problem with dequeueReusableCellWithIdentifier, but I'm not sure how to solve it, the images have been downloaded properly, but after the cell is out of the screen only visible in the cell Will give.

Cell) {cell = [[UITableViewCell alloc] initWithStyle: UITableViewCellStyleSubtitle again: user: cell identifier];} Cell.backgroundColor = [UIColor grayColor]; // If there is no data yet, then empty cells remain empty (node ​​count & gt; 0) {// set up the cell ...

 I did the code like the following,  
  SDWebImageManager * manager = [SDWebImageManager sharedManager]; [manager downloadWithURL: aURL options: 0 progress: no complete: ^ (UIImage * image, NSError * error, SDImageCacheType cacheType, finished BOOL) {if (image) [aCell.imgViewThumb SetImage: image]; That [aCell.imgViewThumb setImage: [UIImage imageNamed: @ "dummy-image.jpg"]]; [ACell.indicator stopAnimating]; }];
