In my app I need to know when Notification or Control center are displayed (I'm displaying some information when app goes to background). In my AppDelegate I "listen" to events like when app goes to background, etc... I workd for all cases....except for Notification or Control center. It is very weird that AppDelegate receives "applicationDidBecomeActive" event when Notification center is displayed. Control center works like it should btw. That makes no sense to me.
Anybody have solution/info regarding this?

Do I want to know if it's possible to detect when a notification from another application is over my app? For example, when the user receives an SMS or Messenger message. Detect the fact that a notification is present on the screen. I don't want the content of the message.
It's an example, It can be a notification for whatever. Because, when a notification is visible, my player's lost because a part of the UI is under the notification. So, if I know when a notification is visible I can change the layout.
It's not possible to handle notifications from other apps. It would be a huge privacy violation.
How can I trigger the following behavior in Swift UI Tests via XCTest:
Get the app to foreground and inactive (applicationWillResignActive) and back to "foreground and active" (applicationDidBecomeActive)
Possible gestures, while app is in foreground and active, could be:
open app switcher and go back to app
open control center and hide control center
open notification center and hide notification center
I searched for something like that following fictive(!) code XCUIDevice.shared.doublePress(XCUIDevice.Button.home) or XCUIDevice.shared.swipeDownFromOutside(); XCUIDevice.shared.swipeUpFromOutside().
Or a more better way a method call to simulate an open app switcher, control center or notification center immediately.
Or in the best way to simulate the status applicationWillResignActive, applicationDidBecomeActive immediately.
Important to understand: the event applicationDidEnterBackground must not called - the app has to stay in foreground (but inactive)!
So recently on wwdc2017 Apple released a convenient way to work with multi app. You can see the multi App portion of the video link below.

I have my application developed on iOS 8 . I have implemented push notification in my application. In iOS 8 clicking on notification automatically clears that particular notification. But my requirement is notification should stay until clear manually. Please give suggestion how to achieve this.
This is a system behavior. You can not prevent this to happen.
If you need something to be always visible from the notification center, consider to create a Notification Center Widget.
In my iOS app I want to know when the control or the notification center appears. Is there a notification specifically for this available? The notifications for applicationWillResignActive and applicationDidBecomeActive do not help in my situation because they are not specific enough.
How can I be notified when the iOS Control Center is being opened?
UIApplicationWillResignActiveNotification isn't good enough since this notification is sent also when the Notifications Center is opened, alert view appeared and other possible scenarios.
I was sure this is not possible, but QuizUp app is notified when the user open the Control Center while the user is on middle of a gameplay to prevent cheating the game.
Thanks
Hey there I did a lot of trial and error investigation and came up with a solution that turns out being very reliable. It works in all orientations and both in fullscreen (no statusbar) and in regular mode. AAWindow is a subclass of UIWindow and you can find it on GitHub.
The way I accomplished this is by overriding sendEvent in UIWindow, separating out TouchEvents from the other events and checking whether touches occur in the bottom 10 percent of the screen (which is the part that can open Control Center). If there are touches and applicationWillResignActive is called within a timespan of .5 seconds (with statusbar) or 3 seconds (without statusbar) you can be very sure that this is because of Control Center being opened. Then a NSNotification is being fired and you can react to that anywhere in the application.
I tested a UIPanGestureRecognizer approach (with and without the status bar visible—changes if the little pull tab comes up instead of control center) along with watching for the applicationWillResignActive notification, and I couldn't reliably know if control center was opened. If the pan was slow enough the gesture recognizer would trigger first, but it's definitely easy to swipe up fast enough to trigger control center and bypass the gesture recognizer firing at all.
Attempting to check if the app goes from applicationWillResignActive and then to applicationDidBecomeActive would be a pretty reliable way to know if the app entered and exited one of a couple states (control center, notification center, answering a phone call, etc), but telling the difference between say notification and control center is impossible this way.
TL;DR: I don't think there is a reliable or accurate way to tell if control center was opened, but QuizUp may be doing something interesting to fake it, and I am open to being wrong!
When Control centre is opened the cycle isn't completed. Means only the method
applicationDidResignActivity will be called but applicationDidEnterBackground won't be called. When app is minimized both methods will be called. Here you can differentiate.
