Is it a strong anti-pattern to use a Floating Action Button in an iOS app?

Floating Action Buttons - invented by the Google Material Design Team - are rather popular on Android. Apple's closest equivalent are perhaps an action icon at top-right or the bottom Tool Bar pattern - which won't play nicely with a persistent Tab Bar.

I'm working on an iOS app that has a very strong, prominent 'hallmark action' that needs to stand out and be accessible from the app's main screen. Should I use a Floating Action Button in iOS?
