Great follow-up to the article that was reproduced in Macworld, with a very instructional video describing how the iOS backgrounding and multitasking process works.
I received a lot of feedback on my recent post on iOS multitasking. I’m sorry I can’t respond to everyone who emailed – there were dozens. I thought it would be worthwhile to look at the process in more detail. I used Instruments (part of the Xcode package) to inspect the free memory on the iPad as I ran and suspended various apps.
