objective c - Can not call class method -

-

i'm building tag-based application , want call same function each tab (viewcontroller).

i'm trying in following way:

#import "optionsmenu.h"  - (ibaction) optionsbutton:(id)sender{    uiview *optionsview = [options showoptions:4];    nslog(@"options view tag %d", optionsview.tag); }

optionsmenu.h file:

#import <uikit/uikit.h>  @interface optionsmenu : uiview  - (uiview*) showoptions: (nsinteger) tabnumber;  @end

optionsmenu.m file:

@import "optionsmenu.h" @implementation optionsmenu  - (uiview*) showoptions:(nsinteger) tabnumber{    nslog(@"show options called");     uiview* optionsview = [[uiview alloc] initwithframe:[[uiscreen mainscreen] bounds]];    optionsview.opaque = no;    optionsview.backgroundcolor = [[uicolor blackcolor] colorwithalphacomponent:0.5f];    //creating several buttons on optionsview    optionsview.tag = 100;  return optionsview;  }  @end

the result never "show options called" debug message , optionsview.tag 0.

what doing wrong?

i understand easy , stupid question, not able solve myself.

any feedback appreciated.

first thing note instance method (and not class method described in question title). means in order call method should have alloc/init instance of class , send message instance. example: 

// note here class names (by convention) begin // uppercase letter, optionsmenu should preffered optionsmenu *options = [[optionsmenu alloc] init]; uiview *optionsview = [options showoptions:4];

now, if want create class method returns preconfigured uiview, try (provided not need access ivars in method):

// in header file + (uiview *)showoptions:(nsinteger)tabnumber;  // in implementation file + (uiview *)showoptions:(nsinteger)tabnumber{     nslog(@"show options called");      uiview *optionsview = [[uiview alloc] initwithframe:[[uiscreen mainscreen] bounds]];     optionsview.opaque = no;     optionsview.backgroundcolor = [[uicolor blackcolor] colorwithalphacomponent:0.5f];     //creating several buttons on optionsview     optionsview.tag = 100;      return optionsview; }

and send message this:

uiview *optionsview = [optionsmenu showoptions:4]; //sending message class here

finally not forget of course add view subview in order display it. hope makes sense...
