hi new programmer.. presently working on iphone....

i know in iphone device if application encounters error iphone os closes automatically.

other exceptions can handled user enterance of numbers, check internet connection ..and many more

my question why exception handling required? because know app close surely...

is tell user why app closed?

i need help... know stupid type question but....? please answer whatever want....comments accepted also(good or bad both)...

because not expected. if users in application , doing , suddenly, forced quit, feel frustruated. telling them reason app closed has no use. users not understand , not care it.

apple wants keep user experience time apps in app store. reason have restricted process see if app gives ux or not
