-

i have perform action when user returns expanded status bar. can do: 1. user touches status bar. using code

[[nsnotificationcenter defaultcenter] addobserver:self                                              selector:@selector(onstop)                                                  name:uiapplicationwillresignactivenotification                                                object:nil];

how detect action: 2. returning status bar? method doesn't work

[[nsnotificationcenter defaultcenter] addobserver:self                                              selector:@selector(onstart)                                                  name:uiapplicationwillenterforegroundnotification                                                object:nil];
