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

Question

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

Answer 1

I solve using this code:

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.


self.namesImage = @[@"page1.png", @"page2.png", @"page3.png", @"page4.png"];

self.pageViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"PageViewController"];
self.pageViewController.dataSource = self;


TutorialContentViewController *startingViewController = [self viewControllerAtIndex:0];
NSArray *viewControllers = @[startingViewController];

[self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];


[self addChildViewController:self.pageViewController];
[self.view addSubview:self.pageViewController.view];
[self.pageViewController didMoveToParentViewController:self];

[[UIPageControl appearance] setPageIndicatorTintColor:[UIColor grayColor]];
[[UIPageControl appearance] setCurrentPageIndicatorTintColor:[UIColor whiteColor]];
[[UIPageControl appearance] setBackgroundColor: [[UIColor blackColor] colorWithAlphaComponent:0.1f]];
[[UIPageControl appearance] setOpaque:YES];

}
