I have a custom button on my view and I want it to do the same functionality as the system-default back button on a navigation Bar = simply remove a view from navigationController displayed by NavigationController.PushViewController(cc, false);
try NavigationController.PopViewController()

I need to add a back button to my navigation page. I tried NavigationPage.SetHasBackButton(page, true); but it didn't work and I tried in xaml also, still does not work. Can anybody help me?
Your code isn't right. In App.xaml.cs you need to set Main page to be new NavigationPage(new ProductDetail());
Then when you navigate away from ProductDetail, you will see the back button.
Also normal page navigation will use PushAsync. Are you wanting a modal popup for your second page?
Is there any way to create a custom PopUp in JavaFX? I can't use tooltip, since I would like it to appear on double click, also I would like a different style than the standard tooltip.
My demands for the popup are:
1. If the user double click, show the popup
2. if the user clicks outside the popup, hide it
See this guide on all the different types of popups.
Use Popup.
Popup popup = new Popup();
// add content (you can add as many nodes as you want)
popup.getContent().add(new Label("Hello Popup!"));
// show (move this to the double-click listener)
popup.show(primaryStage);
// hide (move this to the click listener)
popup.hide();
In XCode 4.5.1 creating a storyboard app with a Navigation controller, I am having a hard time trying to set the BACK button for any view controllers that are pushed. I'm using segue's and the view controller shows as expected. However I want to change the name of the navigation bar and back button dynamically and placed this in my ViewWillAppear:
self.title = #"Select Songs";
[self.backButton setTitle:#"Add"];
changes the title of the navigation bar but the back button still displays the NAME of the pushed window rather than the text "Add".
The Simulated Metrics are all Inferred. I also added a BarButtonItem to the black tray below the view in Xcode and wired up the backButton of the viewcontroller to the backButton, yet the text still does not appear.
Adding the following log messages also yield something interesting: (and yet the titlebar is updating correctly)
-(void) viewDidAppear:(BOOL)animated {
NSLog(#"%s %#", __FUNCTION__, self.navigationItem.backBarButtonItem);
NSLog(#"%s %#", __FUNCTION__, self.navigationController.navigationItem.backBarButtonItem);
}

The accepted answer is a hack, this is the way to do it...
Open StoryBoard
In Document Outline window find ViewController to which you want to
return to
Click on Navigation Item of that ViewController
In Attributes explorer change Back Button value to your custom tile
That is it, enjoy...
The back button will show the title of the previous view and if no title is set it'll show 'Back'.
So in your prepareForSegue method, you can change the title of the current view before the next view is pushed. The back button will then show whatever you set the title to.
I have the navigationcontroller based viewcontroller and I overriding the root view controller navigation bar back button in to my custom segment control with different purpose. This navigation controller is placed one of the separate tab in the uitabbarcontroller. If this is used as the separate tab bar then no problem.
But if i use this navigationcontroller inside the more option in tabbarcontroller i am not able to come back to the more option list because of backbutton is overridden in my navigationcontroller.
My idea is add one back button only if my navigationcontroller is used more option tab otherwise i need to hidden the back button.
Please help me in this issue?
You can check if a view controller is in the 'more' section as follows:
BOOL isOnMoreNavigationController = [tabBarController.moreNavigationController.viewControllers containsObject:myViewController.navigationController];
From a UI consistency perspective it might be better to always show the back button in its standard position and move your custom buttons to some other place.
I have a navigation controller with a root view controller for which i have the customised titleView instead of normal title for the navigation item.
If i pushed a new controller in it , the default back button title is "back", Since i have used custome titleView.
I want it to be different. I tried by setting the title in backbaritem of the root view controller, but no use.
I can create a bar button item in my pushed controller and i can set it as leftbar item, But i want it like a normal back button. [Pointing towards backward]
Is it possible to set title for the back button , if i have a custom titleView ?
Is it possible to create a bar button item as like as default back button.[Pointing towards back , other than plain,border...etc] ?

I got it.
Even though i have custom titleView for my navigation item, I can still set the title for the same navigation item where it wont be taken for the title display in navigation item . but it will taken as the title of the back button when some other controllers are pushed into it.
So , Now i'm having both title [Used for back title display] and titleView [custom view] in the navigation item.
Thanks,
