iOS how to release shared resources, save user data, invalidate timers, and store enough

[tranvutuan]

Hi everyone
My purpose is after hitting the Home button from the device, I want to clear all release shared resources, save user data by using

(void)applicationDidEnterBackground :(UIApplication *)application

Can somebody give me a hint how to do it. Thanks a lot

This really depends on your shared resources and how you deal with user data. You should also really consider if you want to clear those resources just because you went into background. Sometimes it is better to hang onto that memory in case the user is coming right back. If it will take a noticeable amount of time to repopulate then just keep it and release if you get low memory warning.
