reusable UIBarButtonItem in all View Controllers in Objective C - ios

Question

I making custom navigationBar with background color and font size. In addition i have add menu button on right. For this I had made the category named
UINavigationController+Transparent.h
#interface UINavigationController (Transparent)
- (void)presentTransparentNavigationBar;
- (void)hideTransparentNavigationBar;
#end
UINavigationController+Transparent.m
#import "UINavigationController+Transparent.h"
#implementation UINavigationController (Transparent)
UIBarButtonItem *menuButton;
- (void)presentTransparentNavigationBar;
{
menuButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"menu_icon"] style:UIBarButtonItemStylePlain target:self action:#selector(showMenu:)];
[menuButton setTintColor:[UIColor whiteColor]];
self.navigationItem.rightBarButtonItem = menuButton;
UIImage *backButtonImage = [UIImage imageNamed:#"back"];
UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
[backButton setImage:backButtonImage
forState:UIControlStateNormal];
backButton.frame = CGRectMake(0, 0, backButtonImage.size.width, backButtonImage.size.height);
[backButton addTarget:self
action:#selector(popViewController)
forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *backBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
self.navigationItem.leftBarButtonItem = backBarButtonItem;
[self.navigationBar setTranslucent:NO];
[self.navigationBar setShadowImage:[UIImage new]];
[self.navigationBar setBarTintColor:[UIColor wolfRed]];
[self.navigationBar setTitleTextAttributes:
#{NSForegroundColorAttributeName:[UIColor whiteColor], NSFontAttributeName:[UIFont fontWithName:#"Helvetica" size:19.0] }];
[self setNavigationBarHidden:NO animated:NO];
}
- (void)hideTransparentNavigationBar
{
[self setNavigationBarHidden:YES animated:NO];
[self.navigationBar setBackgroundImage:[[UINavigationBar appearance] backgroundImageForBarMetrics:UIBarMetricsDefault] forBarMetrics:UIBarMetricsDefault];
[self.navigationBar setTranslucent:[[UINavigationBar appearance] isTranslucent]];
[self.navigationBar setShadowImage:[[UINavigationBar appearance] shadowImage]];
}
#end
inside my ViewControllers i call
[self.navigationController presentTransparentNavigationBar];
or
[self.navigationController hideTransparentNavigationBar];
The problem is that menu button is not visible and back button is seems like standard iOS blue back button.
Thanks for help!

See I used to customize my navigation bar in following way with
objective c
Step.1 Make sure your View Controller is embed in Navigation Controller
Step.2 Add required icons in your assets eg. "menu_icon" and "back"
Step.3 with the objective-C you can customize navigation bar as like you want.
I always do this way,
#import "ViewController.h"
#interface ViewController (){UIBarButtonItem *menuButton;}
#end
#implementation ViewController
#pragma mark - life cycle methods
- (void)viewDidLoad {[super viewDidLoad];}
- (void)didReceiveMemoryWarning {[super didReceiveMemoryWarning];}
#pragma mark - IBAction methods
- (IBAction)showClicked:(id)sender {[self presentTransparentNavigationBar];}
- (IBAction)hideClicked:(id)sender {[self hideTransparentNavigationBar];}
#pragma mark - Navigation Bar methods
//Customize Naviagtion Bar
- (void)presentTransparentNavigationBar;
{
//Add Menu Button to Navigaiton Bar
menuButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"menu_icon"] style:UIBarButtonItemStylePlain target:self action:#selector(showMenu:)];
[menuButton setTintColor:[UIColor whiteColor]];
self.navigationItem.rightBarButtonItem = menuButton;
//Add Back button to Navigation Bar
UIImage *backButtonImage = [UIImage imageNamed:#"back"];
UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
[backButton setImage:backButtonImage
forState:UIControlStateNormal];
backButton.frame = CGRectMake(0, 0, backButtonImage.size.width, backButtonImage.size.height);
[backButton addTarget:self
action:#selector(popViewController)
forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *backBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
self.navigationItem.leftBarButtonItem = backBarButtonItem;
//Config Navigaton bar settings
[self.navigationController.navigationBar setTranslucent:NO];
[self.navigationController.navigationBar setShadowImage:[UIImage new]];
[self.navigationController.navigationBar setBarTintColor:[UIColor lightGrayColor]];//I used light gray color
[self.navigationController.navigationBar setTitleTextAttributes:
#{NSForegroundColorAttributeName:[UIColor whiteColor], NSFontAttributeName:[UIFont fontWithName:#"Helvetica" size:19.0] }];
[self.navigationController.navigationBar setHidden:NO];
}
//Hide Navigation Bar
- (void)hideTransparentNavigationBar
{
[self.navigationController.navigationBar setHidden:YES];
[self.navigationController.navigationBar setBackgroundImage:[[UINavigationBar appearance] backgroundImageForBarMetrics:UIBarMetricsDefault] forBarMetrics:UIBarMetricsDefault];
[self.navigationController.navigationBar setTranslucent:[[UINavigationBar appearance] isTranslucent]];
[self.navigationController.navigationBar setShadowImage:[[UINavigationBar appearance] shadowImage]];
}
- (void) showMenu:(id) sender{ /*TODO when clicks on Menu button */ }
- (void) popViewController{ /*TODO when clicks on Back button */ }
#end
and if managed everything proper you should be able to get Menu and Back button to navigation bar when you click show button on the screen.
Note:
you can do this in your AppDelegate file so it will available in entire application
