   Hi. I've managed to post new scores, but when I retrieve them, I end up with an invalid string. Here's my request delegate:

   -(void) scoreRequestOk: (id) sender
   {
   NSLog(@"score request OK");
   int it;
   NSArray *scores = [sender parseScores];
   NSDictionary *nd=[scores objectAtIndex:0];

   it=[[nd objectForKey:@"position"] intValue];
   if(it>-1 && it<10) {
   globalHighScores[it].name=[nd objectForKey:@"cc_playername"];
   NSLog(globalHighScores[it].name);
   globalHighScores[it].hiSc=[[nd objectForKey:@"cc_score"] intValue];
   }
   }

   The console at this point shows the correct name at index [0], but then when I try to display it or save it, I get a EXC_BAD_ACCESS, and globalHighScores[0].name shows as 'Invalid'. Here's the global def for globalHighScores:

   typedef struct _highScores {
   NSString *name;
   int hiSc;
   } highScores;

   highScores globalHighScores[11];

   Am I doing it wrong?

   Thanks in advance :)

   Sorry - formatted:

   [code]
   -(void) scoreRequestOk: (id) sender
   {
   NSLog(@"score request OK");
   int it;
   NSArray *scores = [sender parseScores];
   //it=[scores count];
   NSDictionary *nd=[scores objectAtIndex:0];
   NSLog([[nd objectForKey:@"position"] stringValue]);
   NSLog([nd objectForKey:@"cc_playername"]);
   NSLog([[nd objectForKey:@"cc_score"] stringValue]);

   it=[[nd objectForKey:@"position"] intValue];
   if(it>-1 && it<10) {
   globalHighScores[it].name=[nd objectForKey:@"cc_playername"];
   NSLog(globalHighScores[it].name);
   globalHighScores[it].hiSc=[[nd objectForKey:@"cc_score"] intValue];
   }
   }
   [/code]

   [code]
   typedef struct _highScores {
   NSString *name;
   int hiSc;
   } highScores;

   highScores globalHighScores[11];
   [/code]

   ...or not formatted. Sorry - how do the markups work in this forum?

   Probably it's because you didn't retain the NSString for name.

   If your int score in your highscore struct is okay, then your problem with the name is definitely because you didn't do a retain on globalHighScores[it].name=[nd objectForKey:@"cc_playername"]

   If you do a retain, make sure you release it before you reassign something new to it. Otherwise you're wasting memory.

   Forum markup uses angle brackets (less-than / more-than) rather than square brackets. Also, a little easier, you can put backticks before/after your code to get it to format.

   Hi again.

   I got the name to stay set by using retain, now I've run into another problem. I'm using this code:

   
[request requestScores:kQueryAllTime limit:10 offset:0 flags:flags category:cat];


   copied from the sample code, to retrieve the top 10 scores, but I'm only getting 1 back. Is there a reason for this?

   The scores array
   
NSArray *scores = [sender parseScores];
int ij=[scores count];
NSLog(@"Scores count: %1d",ij);

   comes back as a 1. I have saved 8 high scores.

   Thanks again,
   Andrew.

   Wohoo! I'll answer my own question just in case anybody else confuses themselves with this.

   At some stage (after I posted the first high score), I took out the category in the post score routine, but was still requesting the easy scores. Simple matter of adding the category back into the post scores routine.

   Cheers,
   Andrew.
