iOS Tutorial PageViewController

PageViewController is a pages controller (similar to NavigationController and TabBarController) that allows the user to switch pages with a swipe gesture. It is similar to B4A ViewPager.

Using PageViewController is simple. You initialize the controller with the list or array of pages.
The next step is to set it as the key controller:

Private Sub Application_Start (Nav As NavigationController)
   Page1.Initialize("Page1")
   Page1.RootPanel.LoadLayout("Layout1")
   Page2.Initialize("Page2")
   Page2.RootPanel.LoadLayout("Layout2")
   Page3.Initialize("Page3")
   Page3.RootPanel.LoadLayout("Layout3")
   PVC.Initialize("pvc", Array(Page1, Page2, Page3))
   App.KeyController = PVC 
End Sub

Video example:


The example project is attached.

Note that there is no navigation bar. The title is made of a label.

PageViewController is not being recognized as a class, is there a missing file?

 

[Erel]

I forgot to write that it is available in B4i v2.30+

 

[ilan]

is it possible to limit one page to run only in landscape and the second page to run only in portrait??

 

[Erel]

No.

 

[ilan]

ok thanx erel, is your answer related only to the PVC or there is no possibility to do that with b4i?

 

[Erel]

My answer was specific to PVC. However there is no good solution in iOS for automatic rotation of the screen so you shouldn't try to combine landscape only pages with portrait only pages. Start a new thread if you like to further discuss it.

Why toolbar with PageViewController does not work? the Toolbar is visible in the B4i-Bridge but not to run.

 

[Erel]

The navigation and toolbar bars are part of the NavigationController. When you set the KeyController to PVC you replace the NavigationController with a different controller that doesn't include these bars.

Erel,

Alberto this is a community forum. Please don't limit your questions to a single member.

How is this question related to PageViewController?

 

[Alberto Iglesias]

OK...

Because the SideMenuController use PageViewController, and I don´t know if this problem is relative to PVC or SMC

 

[Erel]

Did you add a PageViewController inside the SideMenuController?

 

[Alberto Iglesias]

Now I use the original sample in the forum, like this:

smc.Initialize(pageMenu,  nc, Null)
smc.OpenGesturesEnabled = True
App.KeyController = smc

nc.ShowPage(pageInicial)
nc.NavigationBarVisible = False

but I tried everything, the page that goes left (in this case the pageInicial) is only waiting for the gesture of pulling and "off" the events of that button and whatever else is on the pageview
