Rg.plugins.popup: [iOS] Unable to call DisplayAlert() or DisplayActionSheet while opening PopupPage on a Push-Modal Page

[ShahmanTeh]

Calling a DisplayAlert() or DisplayActionSheet() in PopupPage in iOS will not show any alertViewController. Instead a warning message is shown as below.

Warning: Attempt to present * on * which is already presenting (null)

This works on Android as it only use AlertDialog.

Hi @rotorgames (Kirill),

I apologized earlier for not making any sense in my previous report. I will try explain the details of the stated issue.

I have a ContentPage_A where it is calling PushModalAsync() to ContentPage_B, and from there, I have a called a PushPopupPage(). from PopupPage_A, and here, calling DisplayAlert will not show any UIAlertView dialog.

The debug output that I have received is shown as the following:
Warning: Attempt to present <UIAlertController: *> on <Xamarin_Forms_Platform_iOS_PageRenderer: *> which is already presenting (null)

The following info below are the version that I used to test the issue:
Rg.Plugins.Popup.0.0.16
Xamarin 4.0.3.214
Xamarin.iOS 9.6.1.8
Xamarin.Forms.2.2.0.31
iOS SDK 9.2: (13C75)
IOS Device iPhone 6s Plus iOS 9.2 (simulator)

Here is the video that displays the said issue.

@ShahmanTeh Confirmed

@rotorgames any progress/updates on the issue?

[rotorgames]

@ShahmanTeh It will take many time. Xamarin.Forms architecture is not support DisplayAlert or DisplayActionSheet with Popup plugin. I can add reflections code but it is bad practice.

Please, wait. Maybe I will find solution coming soon. Thx

Fix in v1.0.0
