Can someone guide me as to how can I make an application quit when you press the cancel button of an Alert View in C# code?


I forgot to add that I am trying to quit application on clicking ok button on alert view which I am developing on Unity platform.

    \$\begingroup\$ What is your exact software stack? And why is the task causing issues? \$\endgroup\$ Mar 12, 2013 at 21:26
  • \$\begingroup\$ Do you want a solution in C# or in UnityScript? Your tags are pretty weird \$\endgroup\$

You're not supposed to programmatically quit iOS apps.


Don’t Quit Programmatically

Never quit an iOS app programmatically because people tend to interpret this as a crash. However, if external circumstances prevent your app from functioning as intended, you need to tell your users about the situation and explain what they can do about it. Depending on how severe the app malfunction is, you have two choices.

Display an attractive screen that describes the problem and suggests a correction. A screen provides feedback that reassures users that there’s nothing wrong with your app. It puts users in control, letting them decide whether they want to take corrective action and continue using your app or press the Home button and open a different app

If only some of your app's features are unavailable, display either a screen or an alert when people use the feature. Display the alert only when people try to access the feature that isn’t functioning.

That being said, you can call exit(0) but it's highly not recommended. https://stackoverflow.com/questions/1707685/how-to-quit-an-iphone-app-nicely
