objective c - Using addSubView or presentModalViewController in a standard method with paramaters? -

i'm trying reuse code, have tutorial view controllers / views, call action sheet. however, calling views different. tutorial view(s) need added subview , added navigation controller.

how can expand standard function cater these 2 different situations ?

you can see i'm having instead, means duplicate code :(

i have class called holds standard code, want add calls views here directly.

-(void)showhelpclickbuttonatindex:(int)buttonindex:(uiview *)vw { if (buttonindex == commonuihelppagesbtnidx) {     // nothing } else if (buttonindex == 0) {     nslog(@"tutorial here"); } } 

i use in 1 view ...

- (void)actionsheet:(uiactionsheet *)actionsheet        clickedbuttonatindex:(nsinteger)buttonindex { commonui *cui = [commonui alloc]; [cui showhelpclickbuttonatindex:buttonindex:self.view]; [cui release];  if (buttonindex == commonuihelppagesbtnidx) {     uiviewcontroller *thecontroller = [[helpviewcontroller alloc]           initwithnibname:@"helpview"           bundle:nil onpage:helppagecalcbalance];     [self.navigationcontroller.topviewcontroller           presentmodalviewcontroller:thecontroller animated:yes];     [thecontroller release];    } } 

and view this...

- (void)actionsheet:(uiactionsheet *)actionsheet       clickedbuttonatindex:(nsinteger)buttonindex {    [cui showhelpclickbuttonatindex:buttonindex:self.view];     if (buttonindex == commonuihelppagesbtnidx) {         thecontroller = [[helpviewcontroller alloc] initwithnibname:@"helpview"                              bundle:nil onpage:helppagegettingstarted];          [self.view addsubview:thecontroller.view];    }  } 

maybe actionsheets share 1 same delegate root viewcontroller or appdelegate know according it's current state. hence same actionsheet method used in both case.

if put appdelegate can reached actionsheetdelegate, should able gain control on every way present view, either modally or not in of views + window.

edit (re-edited code): maybe try this

myappdelegate.h:

@interface myappappdelegate : nsobject <uiapplicationdelegate, uiactionsheetdelegate> (...)  - (void) showhelp; 

myappdelegate.m:

- (void) showhelp {     uiactionsheet *actionsheet = [[uiactionsheet alloc] initwithtitle:@""                                                               delegate:self                                                     cancelbuttontitle:@"cancel"                                                 destructivebuttontitle:nil                                                     otherbuttontitles: @"tutorial", @"help pages", nil];      actionsheet.actionsheetstyle = uiactionsheetstyleblackopaque;     [actionsheet showinview:window];     [actionsheet release]; }  - (void)actionsheet:(uiactionsheet *)actionsheet clickedbuttonatindex:(nsinteger)buttonindex {     if (buttonindex == commonuihelppagesbtnidx) {         uiviewcontroller *thecontroller = [helpviewcontroller alloc];         if ([[self lvc] superview] != nil) {             thecontroller = [initwithnibname:@"helpview"                                                            bundle:nil                                       onpage:helppagegettingstarted];             [window addsubview:thecontroller.view];         } else {             thecontroller = [initwithnibname:@"helpview"                                       bundle:nil                                       onpage:helppagecalcbalance];             uinavigationcontroller * navcontroller = [tabbarcontroller selectedviewcontroller];             [navcontroller.topviewcontroller presentmodalviewcontroller:thecontroller animated:yes];         }         [thecontroller release];     } } 

and in viewcontrollers:

- (void)viewdidload {     [super viewdidload];     myappdelegate *delegate = (myappdelegate *) [[uiapplication sharedapplication] delegate];      uibutton *infobutton = [uibutton buttonwithtype:uibuttontypeinfolight];     [infobutton addtarget:delegate                    action:@selector(showhelp)          forcontrolevents:uicontroleventtouchupinside];      uibarbuttonitem *infoitem = [[uibarbuttonitem alloc] initwithcustomview:infobutton];      self.navigationitem.rightbarbuttonitem = infoitem;      [infoitem release];  } 

didn't try should work.
