How to add Navigation bar to a view without Navigation controller

Hello all In my app I have a side menu that slides out to display a table view and form there I have segues that use the reveal view controller. The segue has to connect directly to the view controller otherwise the app crashes so I cant use a navigation controller. My question is how do I add a navigation bar with a bar button item without a Navigation controller.
I have done all my layouts in the story board.

the story board has the navigation item

the app does not

Answer

While there are several smart ways to answer your question. I just solved it programmatically and wrote the following code in my viewWillAppear (note - viewDidLoad is also okay, but not suggested) -

-(void) viewWillAppear:(BOOL)animated {

    UINavigationBar *myNav = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
    [UINavigationBar appearance].barTintColor = [UIColor lightGrayColor];
    [self.view addSubview:myNav];


    UIBarButtonItem *cancelItem = [[UIBarButtonItem alloc] initWithTitle:@"Cancel"
                                                                   style:UIBarButtonItemStyleBordered
                                                                  target:self
                                                                  action:nil];

    UIBarButtonItem *doneItem = [[UIBarButtonItem alloc] initWithTitle:@"Done"
                                                                 style:UIBarButtonItemStyleBordered
                                                                target:self action:nil];


    UINavigationItem *navigItem = [[UINavigationItem alloc] initWithTitle:@"Navigation Title"];
    navigItem.rightBarButtonItem = doneItem;
    navigItem.leftBarButtonItem = cancelItem;
    myNav.items = [NSArray arrayWithObjects: navigItem,nil];

    [UIBarButtonItem appearance].tintColor = [UIColor blueColor];
}

So, you have a white navigation bar with blue bar button items without a Navigation controller. Again, there are other ways to implement it in your case. Hope, this was helpful.

To add images -

UIImageView *myImage = [[UIImageView alloc] initWithFrame:CGRectMake(0,10,32,32)];
[myImage setImage:[UIImage imageNamed:@"image.png"]];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:myImage];
[self.view addSubview:myImage];
