You can use AFNetworking

And simply use: - (void)setImageWithURL:(NSURL *)url;

Or something more complex:

UIImageView image;
NSString *urlstring = [NSString stringWithFormat:@"http://url/"];
NSURL *url = [NSURL URLWithString:urlstring];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[image setImageWithURLRequest:request
              placeholderImage:[UIImage imageNamed:@"placeholder.png"]
                       success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image){
                            // Succes on loading image
                       }
                       failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error){
                            // Fail to load image
                       }];

You can set your image from URL link like this: 

  NSString *your_url = @"http://your_link/";
  image_View.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL   URLWithString:your_url]]];
