UIActionSheet showFromRect autorotacyjna

Question

Jestem pokazując UIActionSheet takiego:

-(void)accessoryPressed:(id)sender{ 
    //Omitted unnecessary objects 

    UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:titleString delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Delete" otherButtonTitles:@"Upload", nil]; 
    //actionSheet.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin; 
    actionSheet.actionSheetStyle = UIActionSheetStyleBlackTranslucent; 
    actionSheet.tag = ((UIButton*)sender).tag; 
    [actionSheet showFromRect:[(UIButton*)sender frame] inView:[(UIButton*)sender superview] animated:YES]; 
} 

Jeżeli przedmiot sender jest UIButton osadzony w dodatkowym świetle UITableViewCell „s.

Problem polega na tym, że iPad jest obrócony, a arkusz akcji nie zmienia rozmiaru (nie oczekuję, że faktycznie ZMIEŃ ROZMIAR, ale chcę, aby był poprawny X, Y) Próbowałem ustawić AutoResizingMask na FlexibleLeft i FlexibleTop, ale to się nie zmienia.

Czy ktoś ma jakiś pomysł, w jaki sposób uzyskać actionSheet, aby wskazać na accessoryView po automatycznym obrocie?

Oto jak to wygląda:

po obrocie -

Answer 1

Szkoda UIKit nie prawidłowo obsłużyć to dla nas. W mojej własnej aplikacji radzę sobie z tym poprzez implementację metody didRotateFromInterfaceOrientation: w moim kontrolerze widoku i ponownym uruchomieniu dowolnego popover przy użyciu zaktualizowanej ramki widoku.

Answer 2

Moim rozwiązaniem jest uogólniona wersja @ rmaddy. To trochę skomplikowane, ale jeśli potrzebujesz ogólnego rozwiązania, aby uzyskać zwroty za rotację, może to pomóc. Mam główny kontroler widoku pojemnik (jeśli chcesz, myśleć o tym jako podklasa UINavigationController), w którym zaimplementować:

- (void) willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration; 
{ 
    [[SMRotation session] viewControllerWillRotate]; 
} 

- (void) didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation; 
{ 
    [[SMRotation session] viewControllerDidRotate]; 
} 

W klasach, gdzie potrzebują go (zwykle nie oglądać klasy Controller), I zarejestruj callbacki. Np

[[SMRotation session].willRotate addTarget:popTip withSelector:@selector(willRotateHelp)]; 
[[SMRotation session].didRotate addTarget:popTip withSelector:@selector(didRotateHelp)]; 

Klasa SMRotation jest następujący:
