I want to show a small notification while my tvOS App is running. The normal UIAlertController alerts are fullscreen and would be disturbing the experience.
Is there a way to use the notifications, which tvOS shows when the remote is connected and so on? They look appear in the upper right corner for a few seconds as an overlay.
Thank You

In my app design, I have a dropdown menu from the top as the user swipes down the top edge of the screen. This interferes with the Push notification tray. Is there any way to disable the default tray dropdown when my app is in the foreground?
Currently, there is no public API for manipulating the behavior of the notification center or how to prevent it.
I think it is a design decision to keep a consistent user experience at the price of developer freedom. I do not think it's not likely that an app will ever be able to block a notification's appearance, and only slightly less unlikely that an app would be able to prevent the notification center from appearing.
After all, it is what made iOS so successful. The consistency between the operating system and apps in general.
Can a Mac app temporarily disable Notification Center, for example while it is doing a full-screen presentation? Apple says alerts are "automatically disabled while you’re presenting in Keynote. They also won’t appear if your display is mirrored on an external monitor." Do third-party apps also have the ability to temporary disable notifications?
I don't think so, but my assumptions are base on iOS, where you can't turn off notification center at all.
You can enable Focus (aka Do Not Disturb) which will hide current notifications and prevent new ones from popping up. See https://support.apple.com/guide/mac-help/turn-a-focus-on-or-off-mchl999b7c1a/mac for how to enable/disable it.
I do not know if applications themselves have control over enabling/disabling Focus.
I use the Touch Bar and add the Focus button to quickly enable it if I need to present or share screen. I do not see a keyboard shortcut you can set in Monterrey like you could in Big Sur.
I'd like to be able to force the keyboard to show on screen in my Metro app. My goal is to test out different layouts/controls and get a feel for the interaction. My problem is that I'm running Win8 on a MacBook Pro (Parallels) and I don't know how to override the physical keyboard and show it on screen instead.
Similarly, I'd like to be able to force rotation if possible.
You could run your app the Simulator. You can put the Simulator in "Touch Mode" and that will interpret mouse clicks as touch events in the on screen controls like Text Boxes and you can choose to rotate the Simulator into profile as well.
Is there any way to remove the swipe event that pulls in the notification center from the top of the ipad when developing an ipad app? If there is an easy way in PhoneGap, that would be best, if not - I can manually implement any Objective-C solution.
The app is already in full screen, and there are some gestures that including swiping at the top. These iPads are distributed to the sales force of this company, and they want that feature (top swipe notification center) disabled.
Cheers!
When your app is in fullscreen mode, Notification Center switches to a two-swipe system: swipe once to bring up a little handle, and swipe down on the handle to bring up Notification Center. This should avoid most interference.
Other than that, there's no public way to disable this gesture.
Of course not. At least not without a jailbroken phone. Notification Center is built into the OS and cannot be disabled by third party apps. As #jtbandes pointed out, their is the "handle" option, but there is no way to completely disable the functionality.
If you have a full screen iOS app and you want to prevent the notification center from being pulled down, can you and how?
Also can you block notification alerts or banners from displaying while your app is loading? (I think this is a no way for sure but wanted to ask just in case.)
It has been my experience that fullscreen apps (statusBarHidden = YES) have a slightly different notification center behavior by default: Swiping down over the area previously occupied by the status bar will only show a little tab. Only swiping the tab will then show the notification center. This has been enough to prevent accidental activation for me so far.
Currently, there is no public API for manipulating the behavior of the notification center. I am of the opinion that it's not likely that an app will ever be able to block a notification's appearance, and only slightly less unlikely that an app would be able to prevent the notification center from appearing. iOS is all about a consistent user experience experience at the price of developer freedom. I could see being frustrated by this kind of functionality if I were an unexpecting user.
All that said, there is always the dark-side of undocumented APIs. I would not be surprised if you could pull off some cleverness using those on a jailbroken device, but that's not my cup-o'-tea.
I just now figured this out. I am developing a game that runs in landscape and whenever I touched the left side, the notification center tab would appear. To fix this, you want to add the following:
setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft
I added this right after I setStatusBarHidden and I no longer have the problem of the notification tab.
Hope that helps.
An API was introduced in iOS 11, alongside a change in behavior to how Notification Center (and Control Center) is presented, to allow you to specify the desired behavior.
UIViewController.preferredScreenEdgesDeferringSystemGestures
In iOS 11+, Notification Center will always pull down when swiping from the very top of the screen, even if the status bar is hidden. preferredScreenEdgesDeferringSystemGestures allows you to specify that swiping a screen edge should not trigger the standard system UI, and instead it will provide a pull-out tab that the user must swipe again to bring out the system UI.
This is intended to be used for games where users swipe frequently, where it would be undesired to bring in system UI instead of control the game. For an immersive app like that, you can return .all to specify you don't want any system UI to appear the first time you swipe any edges of the screen, and it should instead prefer your app's own gestures.
Note that this will disable the ability to swipe once from the bottom to close an app on iPhones and iPads that don't have home buttons - the user will have to swipe twice to close the app.
There is still no way to completely disable Notification Center from within your app, nor prevent notifications from appearing while your app is in the foreground.
I built a very simple code snippet to address this issue programatically. I have a timer set-up in my app delegate that runs every .2 seconds each time it runs it keeps moving the status bar orientation so it doesn't impact the game play. I haven't experienced the annoying notification center in my app since! The only issue is the volume control rotates constantly and might be annoying but it's less annoying than notification center
