Question

I am creating a SQLite database.

To get data from the table I am using this code in appdelegate.m class:

-(void) readItemsFromDatabaseforTable:(NSString *)tableName {
    // Setup the database object
    sqlite3 *database;

    // Init the animals Array
    itemsList = [[NSMutableArray alloc] init];

    // Open the database from the users filessytem
    if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK) {
        // Setup the SQL Statement and compile it for faster access
        NSString *sql_str = [NSString stringWithFormat:@"select * from %@", tableName];

        const char *sqlStatement = (char *)[sql_str UTF8String];
        NSLog(@"query %s",sqlStatement);
        //const char *sqlStatement = "select * from allcategories" ;
        sqlite3_stmt *compiledStatement;
        if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) {
            // Loop through the results and add them to the feeds array
            while(sqlite3_step(compiledStatement) == SQLITE_ROW) {
                // Read the data from the result row
                NSString *aName = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 1)];
                NSInteger aDescription =(compiledStatement, 2);
                //  NSString *aImageUrl = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 3)];

                // Create a new animal object with the data from the database

                Category *item = [[Category alloc] initWithName:aName Quantity:aDescription];

                // Add the animal object to the animals Array
                [itemsList addObject:item];

                [item release];
            }
        }
        // Release the compiled statement from memory
        sqlite3_finalize(compiledStatement);

    }
    sqlite3_close(database);

}

I am getting this array in viewcontroller.m class like this:

MyGroceryListAppDelegate *appDelegate = (MyGroceryListAppDelegate *)[[UIApplication sharedApplication] delegate];
NSLog(@"%@",appDelegate.itemsList);

It displays output like this:

(
    "<Category: 0x6b355d0>",
    "<Category: 0x6b356e0>",
    "<Category: 0x6b35790>",
    "<Category: 0x6b35830>",
    "<Category: 0x6b358d0>",
    "<Category: 0x6b35980>",
)

How can I convert this to normal array?

If you could post the header for the Category object it would give us more to go on. but you would probably want to implement the description method on it.

-(NSString *)description{
    return [NSString stringWithFormat:@"Name:%@ Quantity:%i",self.name,self.quantity];
}
