-(IBAction)downloadImages:(id)sender
{
    NSData *data = [NSData dataWithContentsOfFile:@"pathOfURL"];
    NSError *error = nil;
    GDataXMLDocument *document = [[GDataXMLDocument alloc] initWithData:data options:0 error:&error];
    NSError *err=nil;
    NSArray *nodes = [document nodesForXPath:@"/product_list/product[category = \"Pins & Collectibles\"]/image" error:&err]; 
    NSMutableArray *array =[[NSMutableArray alloc]initWithCapacity:[nodes count]];

    for(int i=0;i<[nodes count]; i++)
    {
        [array addObject:(NSString *)[[(NSString *)[[(NSString *)[[[NSString stringWithFormat:@"%@",[nodes objectAtIndex:i]] componentsSeparatedByString:@"{"] objectAtIndex:1] componentsSeparatedByString:@"<image>"] objectAtIndex:1] componentsSeparatedByString:@"</image>"] objectAtIndex:0] ]; 
    }

    NSLog(@"%@",array);

}

NSLog(@"%@",array); it is showing all the images url in the output console i just need to display them on UIImage in nib file , i am not able to do that so when u click a button all the images should display in a scroll view.

Using the SDWebManager library might help you. https://github.com/rs/SDWebImage

This will help with async download of the urls, then you can use the imageView setImageWithURL: method.
