BugList: Objective C What does -[NSURL length]: unrecognized selector sent to instance 0x

Then its solved with by making string with [NSString stringWithFormat:]

NSString *urlStr =[NSString stringWithFormat:@"%@", [_photosURLs objectAtIndex:indexPath.row]];
NSURL *url = [NSURL URLWithString:urlStr];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *image = [UIImage imageWithData:data];
