Loading Views ObjC Single View Controller - ios

Question

The way I went about coding my app was to load my views through methods in my ViewController.m file.'s implementation. After loading views my app progressed through menus and displays by button actions and updated my setting the self.view to different displays generated by my methods. The problem with this is my memory consumption. Each time a button is pressed my methods that display the next "view" becomes a child and so on. This chews up memory like crazy and I don't want to recode everything (I didn't use storyboard I used only coded). I tried creating a method in an infinite loop that switched views but it wouldn't update self.view. I need a way of switching views using only code (displaying my views with storyboard isn't possible, too complicated to align).
example code:
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
...global vars...
-(void)viewDidLoad {
[super viewDidLoad];
...setup...
[self Load_Main_Menu];
}
-(void)Load_Main_Menu {
...setup UIView display...
UIButton *Button = [UIButton buttonWithType:UIButtonTypeCustom];
[Button addTarget:self action:#selector(PlayButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
self.view=display;
}
-(void)PlayBt:(UIButton*)sender{
[self load_Other_Menus];
}
All navigation and UI is handled as such.
Any ideas for improving memory management and navigation?

try this
-(void)viewDidLoad {
[super viewDidLoad];
...setup...
[self setupButton];
[self displayView];
}
-(void)setupButton {
UIButton *Button = [UIButton buttonWithType:UIButtonTypeCustom];
[Button addTarget:self action:#selector(displayView) forControlEvents:UIControlEventTouchUpInside];
..add button to view
}
-(void)displayView {
...setup UIView display...
self.view=display;
}
