SBApplication *app ;
app = [[objc_getClass("SBApplicationController") sharedInstance]
           applicationWithDisplayIdentifier:@"my killed program id "];
if(app)

now when i trying that in ios 6 i cant get this to work ! need help?

Answer 1

Just to expand on Victors answer a bit... you want to get the pid from the application and if it is greater than 0(a valid pid), kill it with either SIGTERM(Nicer, though it's not guaranteed to kill it) or SIGKILL(Forceful Termination)

SBApplicationController *appController = [objc_getClass("SBApplicationController") sharedInstance];
SBApplication *app = [appController applicationWithDisplayIdentifier:appId];
if (app.pid > 0)
    kill(app.pid, SIGTERM);

Answer 2

Assuming the second app is yours, you could open the second app with openURL and have it kill itself in the App Delegate callback.

Answer 3

How about good old "kill(pid, signal);"?

If you have appropriate (root?) privileges, it should work for you.
