iOS Question A problem using Activity View Controller on iPad.

[PierPaduan]

Hi everyone,
I use Activity View Controller in my app to send files via e-mail.
Using iPhone (iOS 8.4.1) everything works fine, but if I use iPad (iOS 9.3.5) the avc.show(...) produce the following log and the Activity View Controller doesn't appear.

I tried to use the Avc example by Erel (modified only a bit). On iPhone all OK. On iPad the Log is the same and the Avc appear on the Page Title in the top centre of the display, but it's very thin and the icons of the apps are not visible. I can see the icons only if I turn 90 degrees the device. See the two attached pictures.

I upload the simple example project that produce this problem.

Please, can someone help me to fix this?
Thank you very much.

Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(
"<NSLayoutConstraint:0x17e6bf80 V:[UIView:0x17e674a0(>=44)]>",
"<NSLayoutConstraint:0x17e6bda0 UIView:0x17e674a0.height == UIView:0x17e67350.height>",
"<NSLayoutConstraint:0x17e6c990 _UIAlertControllerView:0x17d8e6d0.height == UIView:0x17e67350.height>",
"<NSLayoutConstraint:0x17e84880 _UIAlertControllerView:0x17d8e6d0.height == UIView:0x17d71240.height>",
"<NSLayoutConstraint:0x17d89ac0 'UIView-Encapsulated-Layout-Height' V:[UIView:0x17d71240(21)]>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x17e6bf80 V:[UIView:0x17e674a0(>=44)]>
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

I've tested the example code on an iPad and it looks properly: https://www.b4x.com/android/forum/t...pp-with-activityviewcontroller.73159/#content

Try to anchor it to a button or a BarButton instead of the RootPanel.

Avc anchored to a button and it works. Perfect!!!
Thank You very much Erel.
