i have an iOS app with video player, when the video is playing (landscape, full screen) i would like to hide the home indicator on iPhone X. I have try with
if (@available(iOS 11.0, *)) {
[self setNeedsUpdateOfHomeIndicatorAutoHidden];
}
and also
-(BOOL)prefersHomeIndicatorAutoHidden{
return YES;
}
but no luck. Does anyone have any idea?
When implementing a container view controller, override childViewControllerForHomeIndicatorAutoHidden() method if you want one your child view controllers to determine whether to display the visual indicator. If you do, the system calls the prefersHomeIndicatorAutoHidden() method of the returned view controller. If the method returns nil, the system calls the prefersHomeIndicatorAutoHidden() method of the current view controller
So if you are using childViewController
then need to implement childViewControllerForHomeIndicatorAutoHidden
as -
Swift
extension UINavigationController {
open override func childViewControllerForHomeIndicatorAutoHidden() -> UIViewController? {
return DemoViewController.loadFromNib()
}
}
//DemoViewController is childViewController
class DemoViewController: UIViewController {
static func loadFromNib() -> DemoViewController{
let storyBoardInst = UIStoryboard(name: "Main", bundle: nil)
return storyBoardInst.instantiateViewController(withIdentifier: "DemoViewController") as! DemoViewController
}
override func prefersHomeIndicatorAutoHidden() -> Bool {
return true
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(true)
view.backgroundColor = .red
if #available(iOS 11.0, *) {
//Notifies UIKit that your view controller updated its preference regarding the visual indicator
setNeedsUpdateOfHomeIndicatorAutoHidden()
}
}
}
Objective C-
@interface UINavigationController(custom)
@end
@implementation UINavigationController(custom)
-(UIViewController *)childViewControllerForHomeIndicatorAutoHidden{
return [self.storyboard instantiateViewControllerWithIdentifier:@"DemoViewController"];
}
@end
//DemoViewController is childViewController
@interface DemoViewController ()
@end
@implementation DemoViewController
-(BOOL)prefersHomeIndicatorAutoHidden{
return YES;
}
-(void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:YES];
self.view.backgroundColor = [UIColor redColor];
//Notifies UIKit that your view controller updated its preference
// regarding the visual indicator
if (@available(iOS 11.0, *)) {
[self setNeedsUpdateOfHomeIndicatorAutoHidden];
}
}
