Problems with Asynchronous Image Loading in UITableViewCells Using SDWebImage in Objective-C
I'm trying to configure I'm experiencing an scenario with loading images asynchronously in a `UITableView` using the SDWebImage library. My implementation seems straightforward, but images are sometimes not appearing in the cells, and I suspect it has to do with cell reuse and asynchronous loading. Here's what I have: In my `UITableViewCell` subclass, I am using the following code to load images from a URL: ```objective-c #import <SDWebImage/SDWebImage.h> @interface CustomTableViewCell : UITableViewCell @property (weak, nonatomic) IBOutlet UIImageView *customImageView; @end @implementation CustomTableViewCell - (void)setImageWithURL:(NSURL *)url { [self.customImageView sd_setImageWithURL:url placeholderImage:[UIImage imageNamed:@"placeholder.png"]]; } @end ``` In my `UITableViewController`, I'm calling this method in the `cellForRowAtIndexPath:` method like this: ```objective-c - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { CustomTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"CustomCell" forIndexPath:indexPath]; NSURL *imageUrl = [NSURL URLWithString:self.imageUrls[indexPath.row]]; [cell setImageWithURL:imageUrl]; return cell; } ``` The scenario arises mainly when scrolling quickly. Sometimes, older images appear in cells that should be loading new images. I tried adding `sd_cancelCurrentImageLoad` in the `prepareForReuse` method of the cell to cancel any image requests, but it doesn’t seem to completely solve the question. Here’s what I tried: ```objective-c - (void)prepareForReuse { [super prepareForReuse]; [self.customImageView sd_cancelCurrentImageLoad]; self.customImageView.image = nil; // Reset the image to avoid flickering } ``` Even with that, I still encounter cases where images don’t update correctly or the wrong image appears. I’m using SDWebImage version 5.0.0 and targeting iOS 14.0. Any advice on how to ensure that the correct images load consistently without interference from cell reuse would be greatly appreciated! I'm on Windows 11 using the latest version of Objective-C. Any help would be greatly appreciated!
