Limit number of scans - iOS

[Slaaaap]

Hey,

First of all, thanks for this great plugin! It works great on both Android and iOS platforms.

I still have a problem: I want to limit the number of scans to 1, so I use "maxNumDocuments" set to 1, according to the documentation. This works fine on Android, but not on iOS... I see in the documentation that a video shows the Android example, but we don't have an iOS video... Is "maxNumDocuments" supported on iOS?

Thanks a lot :)
