How to minimize an ios app [duplicate]
(1 answer)
Closed 8 years ago.
In my app I want to minimize/hide my app when user presses an button. It it possible to hide or minimize app on UIButton tap? If so, how?
No, that's not possible. You can put all kinds of functionality on UIButton clicks, but returning to the home screen is not a functionality that is available. Going back to the home screen after an action within the app could be interpreted as a crash.
This is what the home button is there for after all.

How to detect when user clears your app's notification
(2 answers)
Closed 6 years ago.
I have an app that will show a notification icon when the user has not been to the app in awhile I can get it to clear when I launch the app but I want it to clear when they swipe clear from their phone notifications. The code I use to clear when I open the app is
UIApplication.shared.applicationIconBadgeNumber = 0
I just started using swift today to help a coworker on their project. If anyone could point me in right direction at least would be appreciated.
Sorry but you can't "launch code" from your application if your app is not opened. Maybe you could use a shortcut with 3D Touch "Clear" or something more user friendly that would clear the notification badge without launching the app.
You can take a look at the officiel documentation here .

How to prevent my app from running in the background on the iPhone

applicationDidEnterBackground and applicationWillEnterForeground method are not called when pressed home button in iOS simulator
(4 answers)
Closed 6 years ago.
I have an app. We login while using it. It's a multi-user app from the same device with one user at a time. When a user pushed the home button I need to quit the app, not go to background mode. When it goes to background mode it returns to the last active screen rather than the login screen the next tie someone clicks the app icon to enter the app.
How do I either:
close the app with home button press
or which method is called when the app becomes the foreground activity again from the background operation so I could write the code in there that I need to redirect the app to the login view?
Thanks!
Whenever you hit home button, "applicationDidEnterbackground" method will be called.
Assign nil to all the current user variables.
In "applicationWillEnterForeground" Method compare the values of all the current user variables.
If it is nil -> Launch login screen.
Go to your info.plist and add the key "Application does not run in background". This time when the user clicks the home button, the application exits completely.

iOS: Making an App terminate when leave screen
(1 answer)
Closed 7 years ago.
I have a simple game, made using the storyboard.
Obviously, when the user exits the application, it closes and stays in the background (no forced quit or closed).
Is there anything you can do, either in Xcode project settings or programmatically, that will close the app upon exiting, so when the user clicks the app icon, it runs from the start as normal? Just as if it had been manually closed?
Yes there is a way, but NO, you shouldn't do that. Apple will reject your application when you submit it, if you try to exit the app programatically. IOS apps should work the way apple recommends it to work.
From their official site:
Warning: Do not call the exit function. Applications calling exit will
appear to the user to have crashed, rather than performing a graceful
termination and animating back to the Home screen.
EDIT
Just for satisfying your curiosity, you can call exit(0); to close your app programatically.

iPhone detect touch when screen is locked

The default alarm application by apple shows me a snooze button even when the phone is in lock screen and i can press it,so instead of a small button i want to create a larger button or something that will detect a multi touch when a alarm rings,is it possible? can the default lock screen be customized? thanks
As far as I know, the only thing you can get in the lock screen is a push or local notification. This has the default functionality of displaying your app's icon next to some text. You can then slide the icon to launch the app with any extra data you attached to the notification when you created

Currently, I realize that you can't not caught home and lock button simultaneously in iOS app?
If my conclusion is wrong, please point at to me how to detect this event.
Thanks,
Your app delegate method - (void)applicationWillResignActive:(UIApplication *)application
will be called when the user takes a screenshot. If you want to emulate SnapChat then just hide your window in this method (be sure to unhide it in - (void)applicationDidBecomeActive:(UIApplication *)application)
