ios - Adding UIBarButtonItem to UIActionSheet navigation bar (UIDatePicker) -

i created uiactionsheet , added uipickerview on top of it. now, want add 2 button on right , left of uiactionsheet navigation bar title. how can that?

this did far:

- (ibaction)userdidclickedonselectdate:(id)sender {     uiactionsheet *actionsheet = [[uiactionsheet alloc] initwithtitle:@"select birthday date:" delegate:self cancelbuttontitle:@"cancel" destructivebuttontitle:nil otherbuttontitles:@"select", nil];     [actionsheet showinview:self.view];     [actionsheet setframe:cgrectmake(0, 100, 570, 383)]; } 

i'm trying add uibutton in way, can't figure out why can't see on view. when check uiactionsheet subviews, there (maybe somewhere under).

- (void)willpresentactionsheet:(uiactionsheet *)actionsheet {     uidatepicker *pickerview = [[uidatepicker alloc] initwithframe:cgrectmake(10, 50, 50, 216)];      //  configure picker...     [pickerview setdatepickermode:uidatepickermodedate];     [pickerview settag:action_sheet_picker_tag];      //  add picker action sheet     [actionsheet addsubview:pickerview];      //  add button action sheet     uibutton *buttoncancel = [uibutton buttonwithtype:uibuttontypesystem];     [buttoncancel setframe:cgrectmake(5, 100, 200, 200)];     [buttoncancel settitle:@"close" forstate:uicontrolstatenormal];     [buttoncancel setbackgroundcolor:[uicolor redcolor]];     [actionsheet addsubview:buttoncancel];      //  gets array af of subviews of our actionsheet     nsarray *subviews = [actionsheet subviews];     (id button in subviews) {         if ([button iskindofclass:[uibutton class]]) {             [button setuserinteractionenabled:no];             [button sethidden:yes];         }     } } 

this how looks like:

i figure out of there way reach uiactionsheet navigation bar or toolbar (where title located) , add button on top.

thanks in advance.

according people answer's i've managed create better picker view presented same, handles , build way better. i've created uiviewcontroller , added uidatepicker , uitoolbar buttons on top. called that:

- (ibaction)userdidclickedonselectdate:(id)sender {     customdatepicker *custompicker = [[customdatepicker alloc] initwithnibname:@"customdatepicker" bundle:nil];     custompicker.delegate = self;     custompicker.view.backgroundcolor = [uicolor clearcolor];     self.modalpresentationstyle = uimodalpresentationcustom;     [self presentviewcontroller:custompicker animated:yes completion:nil]; } 

i alsvo created delegate tells me when cancel , done buttons clicked:

- (void)datepickerdidcancelled:(customdatepicker *)picker {     [self dismissviewcontrolleranimated:yes completion:nil]; }  - (void)datepicker:(customdatepicker *)picker datedidselected:(nsdate *)date {     nslog(@"selecteddate: %@", date);     [self dismissviewcontrolleranimated:yes completion:nil]; } 

per documentation, shouldn't add subviews uiactionsheets.

uiactionsheet not designed subclassed, nor should add views hierarchy. if need present sheet more customization provided uiactionsheet api, can create own , present modally presentviewcontroller:animated:completion:.
