Save Highscore in Plist-File!

[Franhu]

Hi all!

If i want to save perhaps the best 15 scores the user reached in my game. whats's the best solution? i thought i would save the scores in an array and save the array to a .plist file.
after i closed the app (double klick on home-button and then close the app) and launch it again, then i can load the data from the plist file. is this correct?


thx for help!

Wrap the scores in NSNumbers and store them in an array. Then use NSUserDefaults to save them.

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
[prefs setObject:yourArray forKey:yourHighScoreArrayKey];
[prefs syncronize];

NSArray *highScoreArray = [prefs objectForKey:yourHighScoreArrayKey];

Hey Domele, good to see you again, been learning a lot watching tuts on youtube.

Here is my question, what would be the best way to simplify that code to produce two utility functions like:

saveUserPreferences(scores,"scoreboard")
scores = loadUserPreferences("scoreboard")

and where to put that library for reuse in future projects? Should I create a utils.h/m file and include them in my projects whenever I need that functionality? What would it be your approach to simplify stuff?

I'd create a ScoreBoard data class that has an internal scoreboard array. Then give it methods like addScore:forName: and allScores. Whenever someone calls addScore:forName: or whatever method name you choose that adds a score, have it add it to the array and save it to NSUserDefaults.
