i'm using UIPageViewController in my app and it's working fine. however, it's page control which has been added automatically has a black background which is hiding the current view controller's bottom material (See picture below). is it possible to call the UIPageViewController's page control and change it's color? i want the page control to be shown over the view controller (example, the Path app's walkthrough) like setting the color instead of black to clear.
You can use appearance
to change the color of UIPageControl as otherwise it is not accessible. Try doing it in your AppDelegate's didFinishLaunchingWithOptions
function as given below.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIPageControl *pageControl = [UIPageControl appearance];
pageControl.pageIndicatorTintColor = [UIColor lightGrayColor];
pageControl.currentPageIndicatorTintColor = [UIColor blackColor];
pageControl.backgroundColor = [UIColor blueColor];
return YES;
}
To apply style only to a particular view controller, you can use appearanceWhenContainedIn
instead as following:
UIPageControl *pageControl = [UIPageControl appearanceWhenContainedIn:[MyViewController class], nil];
Only UIPageControl
objects contained in the MyViewController
are going to get this style.
EDIT:
The black background around UIPageControl
at the bottom of your screen is due to the background color of your UIPageViewController
not UIPageControl
. You can change this color as following:
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor blueColor]; //Set it to whatever you like
}
