Braintree payment integration in iOS application

I am looking for the developer who has the experience of the braintree payment integration in the iOS application. And here are some other requirements about the project : - It is an adaptive type of payment (split payment). For example, lets say, customer pay $100 then $90 will be transferred to vendor's account while $10 will be transferred to app owner's account. This should be done in single transaction. - The entered credit/debit cards should be saved for the future use.
