I am changing my view controller using the following code:

 [self.slidingViewController performSegueWithIdentifier:@"FindScoresController" sender:self.slidingViewController];

The segue is PUSH

Now I want to add UINavigationBar Programatically. The code i am using for it is:

// Not required if viewController is pushed from previous viewController
UINavigationBar *navbar = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 64)];
UIColor *barColor = [[UIColor alloc]initWithRed:82/255.0f green:167/255.0f blue:192/255.0f alpha:1.0f];

if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) {
    // iOS 6.1 or earlier
    navbar.tintColor = barColor;
} else {
    // iOS 7.0 or later
    navbar.barTintColor = barColor;

   navbar.translucent = NO;
}
[self.view addSubview:navbar];

It adds nav bar successfully. Now I want to add left and right custom buttons with custom Image. But I am unable to do so.

Code i am using to add right UIBarButton item:

 UIBarButtonItem *flipButton = [[UIBarButtonItem alloc]
                               initWithTitle:@"Flip"
                               style:UIBarButtonItemStyleBordered
                               target:self
                               action:@selector(flipView:)];
self.navigationItem.rightBarButtonItem = flipButton;

But it doesn't show any effect.

I also tried this code:

UIBarButtonItem * item = [[UIBarButtonItem alloc] initWithCustomView:[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"yourimage2.jpg"]]];    
self.navigationItem.rightBarButtonItem = item;

All these code i am writing in ViewDidLoad method.

    Is there a reason for not using `UINavigationController`? – Jakub Vano May 05 '15 at 11:42

    navigationItem is used when your viewcontroller is embedded in a navigation controller. when you setup your own navigation bar you have to use `- pushNavigationItem:animated:`... – André Slotta May 05 '15 at 11:42
  • @JakubVano I am using ECSlidingViewController .... and I have navigation controller also – Rahul May 05 '15 at 11:44
  • if you are using a navigationcontroller then you do not have to add your own navigation bar! remove that code and everything should be fine! – André Slotta May 05 '15 at 11:47
  • You are setting buttons on item of another bar. – Cy-4AH May 05 '15 at 11:48
  • @AndreSlotta I removed that code...now i hav the navigation bar.. but it shows in all other controllers also I want in only few of them – Rahul May 05 '15 at 11:52

    you can show or hide the navigationbar in specific viewcontrollers by setting `self.navigationController.navigationBarHidden = YES or NO` – André Slotta May 05 '15 at 11:53

    the complete signature includes target and selector: `[[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"whatevertheimageisnamed"] style:UIBarButtonItemStylePlain target:self action:@selector(whateverselectoryouwannacall)]` – André Slotta May 05 '15 at 12:00
