Remove Edit Button from moreNavigationController dont work - objective-c

Question

i get some problem by removing the Edit Button from the moreNavigationController.
I cant find the mistake, it must be a simple one.
I create some TabBarViewController connect it in the IB with my TabBarViewController.
Here is the Code:
TabBarViewController.h:
#import <UIKit/UIKit.h>
#interface TabBarViewController : UITabBarController <UINavigationControllerDelegate, UITabBarControllerDelegate>
#end
TabBarViewController.m:
#import "TabBarViewController.h"
#interface TabBarViewController ()
#end
#implementation TabBarViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.delegate = self;
[self.moreNavigationController.navigationBar setBarStyle:UIBarStyleBlackOpaque];
[self.moreNavigationController.navigationBar setBackgroundImage:[UIImage imageNamed:#"navbar.bg.png"] forBarMetrics:UIBarMetricsDefault];
[self.moreNavigationController.navigationBar.topItem setRightBarButtonItem:nil];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
The Edit Button is stil there :/

Answer 1

You need to set the navigationController delegate to your tabBarController. Add the following line in your viewDidLoad method of your TabBarViewController class
self.moreNavigationController.delegate = self;
use the delegate method of UINavigationController navigationController:willShowViewController:animated: to hide the barButtonItem
Use the following code
- (void)navigationController:(UINavigationController *)navigationController
willShowViewController:(UIViewController *)viewController
animated:(BOOL)animated
{
navigationController.navigationBar.topItem.rightBarButtonItem = Nil;
}
This should work, it worked for me.

Answer 2

There is a more pretty solution:
tabBarController.customizableViewControllers = [];

Prasad Devadiga Thanks man!
In my TabBarViewController.m
#import "TabBarViewController.h"
#interface TabBarViewController ()
#end
#implementation TabBarViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.moreNavigationController.delegate = self;
navigationController:willShowViewController:animated:YES;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)navigationController:(UINavigationController *)navigationController
willShowViewController:(UIViewController *)viewController
animated:(BOOL)animated
{
navigationController.navigationBar.topItem.rightBarButtonItem = Nil;
}
#end
In my TabBarViewController.h
I insert this codes
#import <UIKit/UIKit.h>
#interface TabBarViewController : UITabBarController <UINavigationControllerDelegate, UITabBarControllerDelegate>
#end
This is working on IOS7

After reading all of the above and converting it to Swift 3 I noticed that when one of the view controllers which was shown after selecting the More... tab was a navigationcontroller and had a rightBarButton item, that item was removed as well! Since that is not desired, I came up with the following solution:
//
// CustomizedTabBarController.swift
//
import UIKit
class CustomizedTabBarController: UITabBarController, UINavigationControllerDelegate {
var root : UIViewController?
override func viewDidLoad() {
super.viewDidLoad()
root = self.moreNavigationController.topViewController
// Make sure the icons have the proper tint color
if let view = root?.view {
view.tintColor = UIColor.green
}
self.moreNavigationController.delegate = self
}
func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {
// Only hide the rightBarButtonItem when this is the morenavigationcontroller
if( viewController == root ){
navigationController.navigationBar.topItem?.rightBarButtonItem = nil
}
}
}
As an extra I also force the icons shown in the moreNavigationController to be green instead of the standard blue tintcolor since I was using green icons on the tabbar as well.

This worked for me
func tabBarController(_ tabBarController: UITabBarController, didSelect viewController: UIViewController) {
tabBarController.customizableViewControllers?.removeAll()
}
