How to Display and load images from URL that are visible in UITableViewCell

Question

I tried this link, but I didn't get my solution.

I want to display and load images from URL that are visible in UITableViewCell and other cell images have to load when we scroll table view in Objective-C.

use SDWebImage for this. it has almost all features what you need. It's also easy to coding like this.

Objective C

[imageView sd_setImageWithURL:[NSURL URLWithString:@"your domain"]
             placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

Additional:

swift 3:

imageView.sd_setImage(with: URL(string: "your domain"), placeholderImage: UIImage(named: "placeholder.png"))

Rajashekar simply you can do this

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *strCell=@"cell";
    UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:strCell];
    if (cell==nil) {
        cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:strCell];
    }
    NSString *strImgURL = @"YourImageURL";
    NSError* error = nil;
    NSURL *fileURL = [NSURL fileURLWithPath:strImgURL];
    NSData* data = [NSData dataWithContentsOfURL:fileURL options:NSDataReadingUncached error:&error];
    if (error) {
        NSLog(@"%@", [error localizedDescription]);
    } else {
        NSLog(@"Data has loaded successfully.");
    }
    UIImage *img = [[UIImage alloc] initWithData:data];
    cell.imageView.image = img;

    return cell;
}
