Rg.plugins.popup: System.Exception: Failed to marshal the Objective-C object

Created on 16 May 2018  路  7Comments  路  Source: rotorgames/Rg.Plugins.Popup

Today I got this exception (May 16, 2018):
System.Exception: Failed to marshal the Objective-C object 0x111ba62c0 (type: Rg_Plugins_Popup_IOS_Renderers_PopupPageRenderer). Could not find an existing managed instance for this object, nor was it possible to create a new managed instance (because the type 'Rg.Plugins.Popup.IOS.Renderers.PopupPageRenderer' does not have a constructor that takes one IntPtr argument). Additional information: Selector: viewDidLayoutSubviews Method: Rg.Plugins.Popup.IOS.Renderers.PopupPageRenderer:ViewDidLayoutSubviews ()

On April 6, 2018:
System.Exception: Failed to marshal the Objective-C object 0x71c935d0 (type: Rg_Plugins_Popup_IOS_Renderers_PopupPageRenderer).

Both versions: 1.0.4
And I just discovered that this version is the latest stable one and dates back to 2016. Did you guys fixed this since 2016? Do you have any suggestions on which version to use on production?

I just have fixed it. You can see the solution in b8deca7. You couldn't reproduce this issues stably because the exception is thrown only when the last popup was hidden and GC.Collect() was invoked after it.

@cetso Hi. Try to use the last pre/beta release I think that it has been fixed. Also you can read this to avoid main bugs.

Hi @rotorgames
The bug is still there, sadly, even on the newest prerelease. It seems to be an issue with the ACR.Userdialogs Plugin, as it always occures when showing a LoadingScreen from them - though there they told me, they cant fix it on their side. It cant be perfectly reproduced, however the requirement is, that a Plugin.Popup has been shown and then later it happens sometimes during the LoadingScreen. Here is an example of a crashlog:

I also observe it with 1.1.4.158-pre. This is not 100% reproducible, though.

You can see traces of my code in the stacktrace above; the ApiHelper.SafeAreaInsets property is simple:

public static UIEdgeInsets SafeAreaInsets => UIApplication.SharedApplication.Windows[0].SafeAreaInsets;

It looks like accessing Windows property of SharedApplication object may cause Rg.Plugin.Popup to crash, but I'm absolutely clueless why. Any help would be highly appreciated.

I also have the same issue in my projects. I'm trying to fix it now but I think that is is a problem of Xamarin.iOS.

Hello,
I'm using V1.1.4.168 (the latest one) and I'm still having this exception.
Here is it along with the stack trace.
Of course this is happening randomly and I can't figure how to reproduce it.

My bad, looking more closely, the version of my app that has this exception uses version 1.1.4.158-pre of Rg.Plugins.Popup so I guess it has indeed been fixed since.

Sorry for that.
