Identify when the app crashes

Likewise that have functions in Objective-C to know when the screen will Appear, or When the User exit the app, or receive memory warning, I believe there is a way to know when the device will give crash.

If this function exists, I could create an alert will notify the user that the application has an error and the logs would be sent to my email, I wonder if this Possibility exists?.

Grateful.

like every POSIX process, iOS apps receive signals when they're crashing. thats how test flight works.

a) for exceptions use the function NSSetUncaughtExceptionHandler

b) for a signal handler (other crashes then exception) use signal

I won't write all the code here but for further info Ill refer to:
http://www.cocoawithlove.com/2010/05/handling-unhandled-exceptions-and.html

BUT

I would just try to avoid crashing because a handler often isn't really useful and it can very well be tricky to implement a signal handler because everything CAN be in a corrupt state. For example it may well corrupt your CoreData database or user defaults.

Don't ship it I'd say :)
