I just want to know how to kill a back ground process/app in iphone. Just like in Auto Lock SBSettings where, the \"process\" toggle is able to list all the back ground proc
You can't, using the public API. Anything you write wouldn't be allowed on the App Store.
For jailbroken apps, just use ps -ax and kill.
ps -ax
kill
Since you aren't allowed to have any background apps running on the iPhone, this turns out to be something of a non-issue.
