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

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"

    UIBarButtonItem *doneItem = [[UIBarButtonItem alloc] initWithTitle:@"Done"
                                                                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];
