ios - popoverControllerDidDismissPopover NOT doing what I think it should -

so, think when click outside of popover, method popovercontrollerdiddismisspopover should called. know isn't called when dismisspopoveranimated called.

i have simple project have setup shows popovercontrollerdiddismisspopover isn't called:

#import "viewcontroller.h" #import "popoverviewcontroller.h" @interface viewcontroller () { popoverviewcontroller *controller; uipopovercontroller *popovercontroller; } @end @implementation viewcontroller @synthesize button; - (ibaction)showpopover:(uibutton *)sender { if ([popovercontroller ispopovervisible]) {     [popovercontroller dismisspopoveranimated:yes]; } else {     cgrect poprect = cgrectmake(self.button.frame.origin.x,                                 self.button.frame.origin.y,                                 self.button.frame.size.width,                                 self.button.frame.size.height);     [popovercontroller presentpopoverfromrect:poprect                                        inview:self.view                      permittedarrowdirections:uipopoverarrowdirectionany                                      animated:yes];    } } - (void)viewdidload { [super viewdidload]; // additional setup after loading view, typically nib. controller = [[popoverviewcontroller alloc] initwithnibname:@"popoverviewcontroller" bundle:nil]; popovercontroller = [[uipopovercontroller alloc] initwithcontentviewcontroller:controller]; } - (void)viewdidunload { [super viewdidunload]; // release retained subviews of main view. } - (bool)shouldautorotatetointerfaceorientation:(uiinterfaceorientation)interfaceorientation { return yes; }   - (void)popovercontrollerdiddismisspopover:(uipopovercontroller *)popovercontroller {  nslog(@"why never called!!!!");  }  - (bool)popovercontrollershoulddismisspopover:(uipopovercontroller *)popovercontroller { return true; }  @end 

please tell me i'm going wrong or how can detect when popover dismissed.

you never set delegate popovercontroller self.

_popovercontroller.delegate = self;
