当我们有三个UIViewControllers时如何添加返回按钮

Question

I am learning Navigation controller from this link .

I have created it as per this link. However, now what I want is add one more UIViewController before first where I will have a button as My Recipe Book . When I click on this button, I will see the first screen that is there in the example. When I see the second screen (where I will have a list of items (screen 1 in example)), the Navigation bar should have a back button like what I have in above the example in the second screen.

Any idea how to get this done?

I tried adding new UIViewController and adding navigation controller and connecting this UIViewController to first UIViewController in example with MODAL .

It works, however I don't see back button.

Answer 1

I got the answer... Yes I made it finally...

I added new UIViewController and linked this new UIViewController to Navigation controller that is already present.

Earlier :

Navigation Controller >> UIViewController 1 >> UIViewController 2

What I was trying, which was not working

Navigation Controller >> New UIViewController >> Navigation Controller >> UIViewController 1 >> UIViewController 2

Below is what is working

Navigation Controller >> New UIViewController >> UIViewController 1 >> UIViewController 2

Answer 2

set title to each view controller's viewDidLoad method using....

    [self setTitle:@"myViewController"];

and if navigation bar is hidden then make it visible using ......

[self.navigationController setNavigationBarHidden:NO];
