ios6 - Unable to dismiss a UIPopover from another class -

i have ipad app, created in xcode 4.6.3, ios 6.2, arc , storyboards.

i create uipopover programmatically in subviewdata.m.

@property (strong, nonatomic) uipopovercontroller *popover;      //  make rectangle attach popover     cgrect rectangle = cgrectmake( touchpoint.x, touchpoint.y, 110, 1);  //  0 height puts arrow on exact touch point      //  addressability storyboard viewcontroller     uiviewcontroller *popovermainview = [[uistoryboard storyboardwithname:@"mainstoryboard" bundle:nil] instantiateviewcontrollerwithidentifier:@"menuview"];      popover = [[uipopovercontroller alloc] initwithcontentviewcontroller:popovermainview];                             [popover presentpopoverfromrect:rectangle inview:self                             permittedarrowdirections:uipopoverarrowdirectionany animated:yes]; 

i set notifications in class (quickappointment.m) when uibutton in popover has been tapped. notification , issue code calendarviewcontroller.m :

subviewdata *svd = [[subviewdata alloc] init]; [svd.popover dismisspopoveranimated:yes]; 

nothing happens! don't understand why not... so, doing wrong?

look @ code writing:

subviewdata *svd = [[subviewdata alloc] init]; 

this creates completely new , different instance of subviewdata, , not 1 displaying popover.
