ipad - UIPopovercontroller Parent? -

how can "perform selector" parentviewcontroller of uipopovercontroller? have uipopovercontroller lanuched uiviewcontroller, , uipopovercontroller includes other uiviewcontroller. can't seem reach parent view controller either popover or "internal" view controller.

i hope i'm being clear...

btw - parentviewcontroller doesn't work...

thanks!

there's no way directly uipopovercontroller. you're going have pass reference parent view controller view controller you're managing popover controller:

// assumes these calls made within view controller , // myviewcontroller has property called previousviewcontroller  myviewcontroller * myviewcontroller = [[[myviewcontroller alloc] init] autorelease]; myviewcontroller.previousviewcontroller = self; uipopovercontroller * popovercontroller = [[[uipopovercontroller alloc]      initwithcontentviewcontroller:myviewcontroller] autorelease];  uibarbuttonitem * rightbarbuttonitem = self.navigationitem.rightbarbuttonitem; [popovercontroller presentpopoverfrombarbuttonitem:rightbarbuttonitem                           permittedarrowdirections:uipopoverarrowdirectiondown                                           animated:yes]; 

something that, important point view controller (managed popover controller) has grab reference parent view controller before present popover.
