Another newbie question.

I need to store the results of each race in my game. Each race/level has 3 rounds and the average of your 3 rounds determines your overall result for each race/level. I am thinking about storing each round's results in an array in NSUserDefaults and then somehow looping through it to average each player's result. Can anyone recommend a better plan to take? I am using NSUserDefaults to store other common stuff but I wasn't sure if this was over complicating it.

I would look at the sqlite examples as a starting point. You can initialize an array when the application loads, make it accessible to the respective classes that reference this data, and populate your array from the data in a sqlite database..

3 rounds sounds like a job for NSUserDefaults - especially if you already have NSUserDefaults code working. 300 rounds sounds like you should save it to a file or in a database.

If you want to save to a file in the user document folder check out:

OK, I am still struggling with this. I am a web guy so this dictionary stuff is new to me.

I know I can store the data to NSUserDefaults, a file or sqlite but I am unsure how to go about adding it or pulling it back out.

Here is some sample data:
```
Round 1
1st Player 1
2nd Player 3
3rd Player 4
4th Player 2 

Round 2
1st Player 3
2nd Player 1
3rd Player 4
4th Player 2

Round 3
1st Player 1
2nd Player 4
3rd Player 2
4th Player 3

Average finish
Player 1 1.33
Player 2 3.33
Player 3 2.33
Player 4 3.33

Final Results:

    * 1st: Player 1
    * 2nd: Player 3
    * 3rd: Player 2
    * 4th: Player 4
```
If I create a dictionary would the player names be in 1 array then each rounds results each be in additional array? If so, how do I correlate the player with their results?

I am thinking about just using sqlite as I know I should be able to write a query to avg distinct user's results.

First of all, if you are a web guy and you are more comfortable read/writing xml, do that!

If youve already built an object to handle your data, make it serializeable and save that.

But if you want to use NSUserDefaults, maybe:

Make a Dictionary with keys @"Round1", @"Round2", @"Round3", @"Average", @"Final".

For all of them I would put an NSArray of four NSNumbers which correspond to which player had which spot (or for Average you put the average)

Make sense?

I guess my biggest hang up with any option is looping through and getting averages for each user. I know in SQL I can do AVG() and group by user. I am not sure how to go that route using a PList and arrays.

OK - I started composing my post before you wrote that you decided on sql, I only saw that post after mine went through. SQL it is!
