NativesSript monetization plugins


I’ve been searching for some plugins to monetize the NativeScript apps, but just found one for adMob, which I am not interested in Do you guys know any alternatives?
On the other side, I am trying to create my own IOS plugin for StartApp and Vungle, but I can’t find the way to convert the .framework provided to a cocoapod library. Would you please point me some tutorial about how to do it?
