Accessing to MBaaS services

Hello,

I am trying to study about FeedHenry MBaaS services. I already have an iOS project, which has developed in Native. Can I use my existing iOS/Android native project and utilize Feedhenry's MBaaS services? I got this doubt because when I'm reading about RH's Mobile platform, it shows me that I have to create mobile project thru RH mobile platform and then utilize MBaaS if require, I can't use my existing already developed iOS native project (developed using xcode) and just to utilize MBaaS services?
Is my understanding correct or wrong? Please advise.
