UIPageControl - How to make the background transparent?

Question

I am using UIPageControl and trying to make the background transparent.

UIPageControl *pageControl = [UIPageControl appearance];
pageControl.pageInd         


        

Answer 1

It could work if you set the background color of the UIPageControl to a background image that looks the same as your VC's background color:

[UIPageControl appearance].backgroundColor  = [UIColor colorWithPatternImage:[UIImage imageNamed:@"pageControllerBackground"]];
