Here you go!

-(NSInteger)dbFieldCount:(NSString *)dbname
{
    NSString *query = [NSString stringWithFormat:@"PRAGMA table_info(%@)",dbname];
    const char *query2 = [query UTF8String];
    NSInteger nFields =0;
    sqlite3_stmt *compiledStatement;
    if(sqlite3_prepare_v2(database, query2, -1, &compiledStatement, NULL) == SQLITE_OK) 
    {
         while(sqlite3_step(compiledStatement) == SQLITE_ROW)
         {
               nFields++;
         }
    }
    sqlite3_finalize(compiledStatement);
    return nFields;
}
