When design iPhone applications, I have several questions:
Q1 : what considerations if suddenly calling when app is running ? similar with SMS, low power notification etc. (what else ? )
Q2 : what should do for low memory ?
Q3 : how to save data when quitting ?
......
All those questions are related with UIApplicationDelegate.
The app is standalone process, usually UIApplication inherit UIResponse, and confirm to UIApplicationDelegete, there must have one process which will manage all apps process, this manager process must know UIApplicationDelegate, and handle different cases like above.
My questions are: 1. What is big picture for the workflow to handle one app via UIApplicationDelegate ? 2. what else other special features related with UIApplicationDelegate ?
Thanks
