Can I create custom function to insert/update that can be reused for many tables in SQLite?

I'm a newbie in iOS and this is my first programming language. I try to create a custom function that can be reused for different tables ( have different number of data fields) in SQLite.

How can I do it? I read many example about SQLite in Objective-C but I couldn't find an answer (or just my search skill are bad). Please help me answer this question or just suggest me how to do, thanks.
