How do I make the bottom bar with dots of a UIPageViewController translucent?

I\'m in the process of making a tutorial, and I\'m trying to emulate the style of Path\'s tutorial like so:

Small hack I found today..

Please see the code below.

self.pageController.dataSource = self;
    CGRect rect = [self.view bounds];
    rect.size.height+=37;
    [[self.pageController view] setFrame:rect];
        NSArray *subviews = self.pageController.view.subviews;
        UIPageControl *thisControl = nil;
        for (int i=0; i<[subviews count]; i++) {
            if ([[subviews objectAtIndex:i] isKindOfClass:[UIPageControl class]]) {
                thisControl = (UIPageControl *)[subviews objectAtIndex:i];
            }
        }

        UIView *tempview = [[UIView alloc] initWithFrame:CGRectMake(0, -30, 320, 40)];
        [tempview addSubview:thisControl];
        thisControl.pageIndicatorTintColor = [UIColor lightGrayColor];
        thisControl.currentPageIndicatorTintColor = [UIColor greenColor];
        [self.view addSubview:tempview];
