Fetching data from MBO in native IOS app

Hi SupDevelopers,

What I am trying is that i have simple push pull application where i want to fetch data from MBO and show that in drop down menu in application the application part is not an issue but real problem starts when i start the connectivity as i a new to SUP environment but some how i managed that with the help of my colleague now i am stuck up at fetching data from imported MBO files to the front end so i am expecting some help from you guys and help me out a good reference would also do the work and reference for punching data back to the system would be a plus.

I am using SUP 2.1.2,xcode,BAPI's for various fields.

Thanks &regards
