Getting an image fails to create NSURL

Question

Im trying to get an image from a url link.

        NSURL *thmbnailUrl = [NSURL URLWithString:[NSString stringWithFormat:@"http://%@:800/fishtune/movie/%@.png",[[DBHelper sharedInstance] currentHostIP],[arr objectAtIndex:0]]];
        NSLog(@"thmbnail:%@",[NSString stringWithFormat:@"http://%@:800/fishtune/movie/%@.png",[[DBHelper sharedInstance] currentHostIP],[arr objectAtIndex:0]]);
        NSData *data = [NSData dataWithContentsOfURL:thmbnailUrl];
        NSLog(@"movimgdata:%@",data);
        UIImage *img = [[UIImage alloc]initWithData:data];
        NSLog(@"movimg:%@",data);
        NSData *imgData = UIImagePNGRepresentation(img);

when i log thmbnail i get this "ipofserverinnetwork/fishtune/movie/Our Logo 480p back.png" Note:i didn't put the original ip.

I get null when i log data and of course img will also be null. I really dont know why I'm getting null. because when I tried entering the url in a browser it displays the image. I used the same code in another part of my app and it works but when i used it in this it fails. Is it because of the spaces between "Our_Logo_480p"?

you might need to use

NSString* escapedUrl = [yourstring stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

yes it's because of spaces, use

 NSString *myUrl = [NSString stringWithFormat:@"http://%@:800/fishtune/movie/%@.png",[[DBHelper sharedInstance] currentHostIP],[arr objectAtIndex:0]];
   NSString *url = [myUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
