Xamarin form Navigation page back button not displaying

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?

Swipe to go back in navigation controller on iOS 7

I've been looking through the iOS 7 / UIKIT framework, and although it looks quite different aesthetically it's really the same SDK underneath from what I can see.
My question, is there any extra code that needs to be included to get the draggable behaviour between pushed tableviews/views?
When you push a view onto a UINavigationController you can now drag back to the previous controller from the side rather than pressing the back button.
This behavior can be seen in mail.
How is this achieved, do I need to add any code to add it to my app?
This has nothing to do with UITableView or UITableViewController, but with UINavigationController. And yes, you get this behavior for free as long as the back button is visible.

Combining a navigationcontroller and a root view controller with pages

I have a problem that has been solved on iOS6, but still appears if I use the iOS 5.1 simulator.
I have a default page based application. I added a "Main menu" view controller, that has three buttons that activate the root view controller containing the pages via a push segue, all defined in the storyboard.
I then added a navigation controller and made it the initial view controller.
If I pas the menu via a button and flip a few pages I can click the back button and it goes back to the menu. Good.
But I don't want the nav bar, so I hide it, and on the root view controller that contains the page view controllers I add a button which performs this action:
[self.navigationController popToRootViewControllerAnimated:YES];
This button works perfect on iOS6, I can flip a few pages, press the button and I'm back in the menu.
With the iOS 5.1 simulator however (and on my 5.1 iPad), a page flip occurs! It's a page filp until I'm on the last page and then I go back to the menu.
I searched for over two hours now but could not find a solution, I hope someone can help me with this?
Note: setting animated to NO does not solve the problem.
I did find the answer to my question, this is my first iOS project which explains why I did not find it any sooner myself.
In the default page based application there are two lines in the viewDidLoad method:
// Add the page view controller's gesture recognizers to the book view controller's view so that the gestures are started more easily
self.view.gestureRecognizers = self.pageViewController.gestureRecognizers;
First, it's not really adding but assigning that happens here, second, when I put the second line in comment, everything works as expected.
So I'm glad it solves my problem, however it raises some questions:
The gestures are started as easy as they were, so why was this line needed in the first place, what does it supposedly fix?
Why does it work in iOS6? It should have had the same problem, no?
Is it correct that it is an assignment and not an addition?
Any answers to these three are still appreciated.

Disable UIPageViewController when ModalViewController opened

I am totaly new to this site, but I already like it :-)
I found it by searching for a question about the UIPageViewController.
I have a normal UIPageViewController App, in which I open a ModalViewController for setting up some settings...
Now the Problem: :-)
If I click on the done Button on the right side of the ModalView, to dismiss it, the PageViewController turnes the page, because he thinks that he is meant by that click ;-)
Can I disable the PageViewController GestureRecognizer as long as I have a ModalView opened?
Is there a method to disable and later his recognizer?
thank you for your help in advance...

It seems odd that your UIPageViewController would steal touches from a modal view presented over it. Unless, perhaps, you are embedding the modal view within the content of the UIPageViewController?
To answer your question -- you can easily disable the page view controller's gesture recognizers by enumerating its gestureRecognizers property (an NSArray):
for (UIGestureRecognizer *gr in [self.pageViewController gestureRecognizers]) {
[gr setEnabled:NO];
}
Re-enable them later with setEnabled:YES.
UPDATE:
In iOS 6 UIPageViewControllerTransitionStyleScroll has been added. UIPageViewControllers that use this transition style return no gesture recognisers in the array returned by gestureRecognizers. Presumably page view controllers with this transition style use an underlying, private UIScrollView instance (it behaves just like a UIScrollView with paging enabled), although I haven't checked this.

UITabBarController not using NavigationController

I'm using MonoTouch and my application setup looks something like this,
NavController
-TabBarController
-NavController
-View1
This works then I click on a tab and am directed to View1. The problem is that this was performed by the tabBarController and not the navigationController. So I get no Back button. Is there a way to capture a TabItemClicked event and manually use the NavigationController to push the View1 onto the stack? So I can get a back button.
I'm hiding the TabBar once I get to View1, so at the moment, there is no way back from View1.
Hope it may help you
