I'm using a TabbedPage where a certain action in one tab will cause the app to change its current tab. All tabs are MasterDetailPages. During this change, if an iOS device is in portrait, the Detail view will not automatically slide away or change to that of the new page. This means that you're stuck with the old detail view, and as soon that you tab somewhere to make it slide away, an error occurs.
In order to fix this, I'm trying to set the IsPresented of the page I'm navigating away from, however, this also causes the same error.
My question is: Does anyway know of a workaround? I was thinking of waiting for the navigation to end before changing the tab, but there doesn't seem to be any way to do this.
The error message I'm receiving is:
Objective-C exception thrown. Name: NSInvalidArgumentException Reason: -[UIPopoverController _presentPopoverBySlidingIn:fromEdge:ofView:animated:stateOnly:notifyDelegate:]: Popovers cannot be presented from a view which does not have a window.
