iOS Question iPhone orientation lock

[cwt]

Looked all over but could not find how to do this - how do I lock the device orientation for a single page to either landscape or portrait in B4i?

In Visual designer under go to Windows->Variants and set new Variant by clicking on New Variant and select from the pop up menu

I may be missing something here but I know how to use the Visual Designer - I have been using B4A for years and I know how to lock a window in Android to either landscape or potrait. But I cannot see how or where to do that in iOS. What am I missing?

I think the setting will apply to all pages.

#iPhoneOrientations: Portrait, LandscapeLeft, LandscapeRight 
#iPadOrientations: Portrait, LandscapeLeft, LandscapeRight, PortraitUpsideDown 
#Target: iPhone, iPad

[f0raster0]

are you speaking about

#iPhoneOrientations: Portrait
#iPadOrientations: Portrait

??

 

[cwt]

Yes, I am referring to

#iPhoneOrientations: Portrait
#iPadOrientations: Portrait

But on a page-to-page basis, not globally. Is this possible?

Interface orientations for separate pages

Usage. 1) Add pageOrientation module to your project. 2) After each ShowPage call setInterfaceOrientations function. For example, pageOrientations.setInterfaceOrientations (Page2, "LandscapeLeft, LandscapeRight") 3) If you want to ignore invalid orientation (let's say, in Page_Resize event)...

Semen,

I am using B4XPages and your code does not appear to work with this. Do you have a version for B4XPages in B4i ?

 

[Semen Matusovskiy]

pageOrientation.bas, as it is, works with B4XPage, because finally all is based on UIViewController.

To find native Page is simple (B4XPages.GetNativeParent (Me)). But there is a small problem in which event to insert a call of pageOrientations.setInterfaceOrientations.
A correct place is to insert inside B4XPages.ShowPage, but to do this is necessary to reconstruct a library (not a good idea).
