Destroying iOS application programmatically on failed login attempts

Question

My client has come up with a strange requirement. He wants the iOS application to be deleted from the iPad/iPhone on 5 unsuccessful login attempts. I want to tell him that, its just NOT possible. Does anyone know any way of programmatically write a piece of code to self destruct an iOS app ?

Answer 1

At least on non-jailbroken devices this won't be possible. I mean, you can't even close an app without the user explicitly pressing the Home button. Also, the user could just re-download the app, rendering self-destruction moot.

You could - as is common in the Internet - just ban the client's IP or UDID for a while. Or store the number of login attempts on the device and refuse to let the user log in after too many attempts.

Answer 2

You can lock the user out of the application, and delete all of the cached data. But no, you can't erase it.

I suppose you could call abort() on every launch after 5 failed attempts, but I'm not sure you'll get through review if that happens.
