I am creating a revision application for my computer science class, I have very limited knowledge in regards to programming in Xcode/Ob C, can anyone assist me and tell me what is going wrong here? My database is named "Questions" and contains 2 tables: "EasyandMedium" as well as "Hard", however, I cannot get my program to save data to this database - Please Help!

Answer 1

What exactly is the problem you are having? Do you know if your fileExistsAtPath call succeeds? Does the sqlite3_open call succeed?
There are lots of examples for using SQLite3 in Xcode such as I am having trouble linking my XCode Project with my SQLite3 database. I would suggest checking one out as they make a great starting point.
