ios - How do I properly add a button to my scene using only code? -

working off of other stack overflow answers have managed come code below.

(in homescreen.m file)

 uibutton *gcbutton;    -(id)initwithsize:(cgsize)size {      if (self = [super initwithsize:size]) {           //add button          [self addgamecenterbutton];        }      return self;  }     -(void)addgamecenterbutton  {      gcbutton = [[uibutton alloc]initwithframe:cgrectmake(50, 20, 30, 30)];      [gcbutton setbackgroundcolor:[uicolor orangecolor]];      [gcbutton settitle: @"my button" forstate:uicontrolstatenormal];      [gcbutton settitlecolor: [uicolor bluecolor] forstate:uicontrolstatenormal];      [gcbutton.layer setborderwidth:1.0f];      [gcbutton.layer setbordercolor:[uicolor bluecolor].cgcolor];      //adding action programatically      [gcbutton addtarget:self action:@selector(buttonclicked:) forcontrolevents:uicontroleventtouchupinside];      [self.view addsubview:gcbutton];     }   -(void)buttonclicked:(uibutton*)sender  {      nslog(@"you clicked on button %ld", (long)sender.tag);  } 

as of right see nothing on screen. else need add in .m or .h files make button work?

thanks in advanced help

from comments of question, i'm assuming using spritekit. in gamescene, unfortunately, cannot use uibuttons normally.
