In iPod or iPad devices, when an application is running and the user presses the home button, the app goes into the background – but it still occupies some memory.
What happens if a number of other apps take up more and more memory similarly?
In my case, my app crashes with a memory warning – is there any solution or particular technique I should use?
In brief,
actually i open one Cocos2D application after some time i will come in home screen icon and after that i open second cocoa2d application i got very less memory to drive this current app. I mean suppose if 1st app takes 80MB RAM and other application take (total device RAM memory – 80MB). can it possible ? id yes then why? How i tackle this problem becoz due to 1st application i will not able to drive 2nd application
The first thing you should do is read the Apple documentation relating to App States and Responding to Low-Memory Warnings in iOS
