Option to hide iPhone X home indicator + Edge Protection

We have adapted our game to iPhone X design and got a feedback from Apple representatives that they suggested to hide the home indicator in game and enable "Edge Protection" (swipe up once to show home indicator, swipe up again to go back home as said here)

I believe it's not there yet in Unity? It will be great if Unity can add this in (just an option below "Status Bar Hidden").

There's a post on how to do this with iOS native code. I don't really understand so better wait for Unity...

Here is the feature request I made, vote it up if this matters you.

 

Very nice, please do update here if that's implemented in any new version/patch.

 

You can do it yourself for now if you use Xcode 9.

Add

- (BOOL)prefersHomeIndicatorAutoHidden
{
    return YES;
}

To UnityViewControllerBaseiOS.mm

 

This is for both status and edge protection

UnityViewControllerBaseiOS.h

Code (CSharp):

1.  
2. @interface UnityViewControllerBase : UIViewController
3. {
4. }
5.  
6. - (BOOL)shouldAutorotate;
7.  
8. - (BOOL)prefersStatusBarHidden;
9. - (UIStatusBarStyle)preferredStatusBarStyle;
10. - (UIRectEdge)preferredScreenEdgesDeferringSystemGestures; // add this
11. - (BOOL)prefersHomeIndicatorAutoHidden; // add this
12. @end
13.  

UnityViewControllerBaseiOS.mm

Code (CSharp):

1.  
2. - (BOOL)shouldAutorotate
3. {
4.     return YES;
5. }
6.  
7. // add this
8. - (BOOL)prefersHomeIndicatorAutoHidden
9. {
10.     return YES;
11. }
12.  
13. // add this
14. - (UIRectEdge)preferredScreenEdgesDeferringSystemGestures
15. {
16.     return UIRectEdgeAll;
17. }
18.  
19. - (BOOL)prefersStatusBarHidden
20. {
21. ....
22.  

 

Hi guys,

Whenever I add this, my home indicator disappears, yes, but as soon as I tap the screen (anywhere, and not even doing a swipe), home indicator appears again. Is this the expected behavior? It makes Home Indicator even more annoying, since my game is a point and click, and you are tapping the screen all the time. I hope I'm missing something :/

 

I'm using the option for hiding it that unity added on the last patch (Unity 2017.2.0p2) and same thing happens, so I guess it's the expected behaviour.

I don't see the point on hiding it on any app or games, it's just distracting. I only see it useful if you are watching a video or something like that.

 

I agree that it's primary intention is most likely watching videos. Let's hope that they make it optionally hide completely so that we can take full advantage of the real estate.

 

I'm going to give this a test, but if the behaviour is as you've described then I don't think it's the only way to enable edge protection. I was playing Campfire Cooking on an iPhone X and it had edge protection turned on. In that game the home indicator stays low opacity until you actually swipe up on (or near) the home indicator, and doesn't activate on every screen tap.

 

Ok, i just ran some builds on 2017.2.0p2 I think the behaviour most people want is just putting on bottom edge protection, and not enabling auto-hide. Auto hide of the bottom bar in unity settings will (as you described) hide the bar completely, but show it full brightness on any screen tap. But if you just set the deferred gesture protection on the bottom bar, it will fade out the bar mostly and will only enable when you swipe near the bar (requiring a double swipe to dismiss your app).

This is the way Campfire Cooking was behaving, and I think the iOS recommended way. Auto-hiding basically was only recommended for video-player like applications. In fact they don't really recommend doing either option, but I think if your game has issues conflicting with the gesture they're ok with it.

 

@acproctor
Thanks, we don't have an iPhoneX to test yet and your answer seems solid and we will just fellow~

 

Hey, I find your request, you can try to add the following code in the
UnityViewControllerBase class, and then there are no changes in other places.
- (UIRectEdge)preferredScreenEdgesDeferringSystemGestures

{

return UIRectEdgeAll;

}

 

FYI, I do see a "Hide Home Button on IPhoneX" in Unity 2017.3 f2

 

Hey guys, I want to completely remove the home bar in iPhone X. jeffweber "Hide Home Button on IPhoneX" option hides it but it is visible immediately after we touch the screen. It's not practical for games. I don't want to see the home bar at all unless I swipe up from bottom. Is it possible?? Any Unity officials to reply??

 

@povilas: Hi. https://itunes.apple.com/in/app/true-skate/id549105915?mt=8 - This game completely removes home bar in iPhone X, so it's possible. Are you saying it's not possible within Unity? Can we modify generated Xcode project somehow to do that?

 

No it doesn’t. They’re just deferring swipe gestures from the bottom, which can absolutely be done from within Unity.

 

@_Daniel_ Are you sure? I've tried to use defer option from Player Settings and it did not work in iPhone X Xcode simulator.

 

Did you have Auto Hide Home Indicator disabled? It must be disabled in order for deferring to work.

 

@_Daniel_ No I did not do that. Thank you for your help. I will try that now.

 

Does anyone know how i find and edit these files?

Do i do it in xcode after Unity has created the xcode project?

 

I found them. For other non coders like me, They are inside the build folder Unity creates for your ios project. I did a spotlight search to find them. Double clicking them opens them up in xcode, although i haven't figured out how to save edits to them yet. Also the .h file opens in a seperate window, but you can still edit it in there.

 

Hi dhanrajsinh24 did you find if using the "Deferring" option and disabling the "Hide home button" worked? I tested this setup on the Simulator, but it didn't work as well.

 

Why doesn't Unity have this option enabled?

The above solution worked great but the classes file name changed:
UnityViewControllerBase+iOS.mm
UnityViewControllerBase+iOS.h

Code (CSharp):

1. - (UIRectEdge)preferredScreenEdgesDeferringSystemGestures
2. {
3.     UIRectEdge res = UIRectEdgeNone;
4.     if (UnityGetDeferSystemGesturesTopEdge())
5.         res |= UIRectEdgeTop;
6.     if (UnityGetDeferSystemGesturesBottomEdge())
7.         res |= UIRectEdgeBottom;
8.     if (UnityGetDeferSystemGesturesLeftEdge())
9.         res |= UIRectEdgeLeft;
10.     if (UnityGetDeferSystemGesturesRightEdge())
11.         res |= UIRectEdgeRight;
12. //    return res;
13.     return UIRectEdgeAll;
14. }

Code (CSharp):

1. - (BOOL)prefersStatusBarHidden
2. {
3.     static bool _PrefersStatusBarHidden = true;
4.  
5.     static bool _PrefersStatusBarHiddenInited = false;
6.     if (!_PrefersStatusBarHiddenInited)
7.     {
8.         NSNumber* hidden = [[[NSBundle mainBundle] infoDictionary] objectForKey: @"UIStatusBarHidden"];
9.         _PrefersStatusBarHidden = hidden ? [hidden boolValue] : YES;
10.  
11.         _PrefersStatusBarHiddenInited = true;
12.     }
13. //    return _PrefersStatusBarHidden;
14.     return YES;
15. }

 

I really want to know how to custom Indicator home. I know that it cannot hide.. it's ok for me
But, it too bright why it cannot custom it or just changing a color?
it would be better, it so white and bright!

 

Wow, this is nice.

I also come across how to add widgets on iOS and some other cool iOS features recently.
