UIImage *clouds = [UIImage imageNamed:@"Clouds"];
UIImageView *cloudView = [[UIImageView alloc] initWithImage:clouds];
CGRect origin = CGRectMake(320, 0, clouds.size.width, clouds.size.height);
CGRect destination = CGRectMake(0, 0, clouds.size.width, clouds.size.height);
cloudView.frame = origin;
[self.view addSubview:cloudView];
[UIView animateWithDuration:5 delay:0 options:UIViewAnimationOptionRepeat | UIViewAnimationOptionCurveLinear animations:^{
    cloudView.frame = destination;
} completion:nil];
