    <p>I have a problem with sending an array of integers via GKSession.</p> <p>This is how I did it:</p> <p>To send it.</p> <pre><code>-(void)sendData { NSMutableArray *myArray = [[NSMutableArray alloc] init]; [myArray addObject:[NSNumber numberWithInteger:snakeHead.position.x]]; [myArray addObject:[NSNumber numberWithInteger:snakeHead.position.y]]; [myArray addObject:[NSNumber numberWithInteger:direction.x]]; [myArray addObject:[NSNumber numberWithInteger:direction.y]]; [myArray addObject:[NSNumber numberWithInteger:bodyOffsetX]]; [myArray addObject:[NSNumber numberWithInteger:bodyOffsetY]]; [myArray addObject:[NSNumber numberWithInteger:amountBodies]]; NSData* encodedArray = [NSKeyedArchiver archivedDataWithRootObject:myArray]; [snakeSession sendData:encodedArray toPeers:snakePeers withDataMode:GKSendDataReliable error:nil]; [encodedArray release]; } </code></pre> <p>The sendData function is called from a scheduler.</p> <p>To receive it.</p> <pre><code>-(void)receiveData:(NSData *)data fromPeer:(NSString *)peer inSession:(GKSession *)session context:(void *)context { NSArray *hisArray = [NSKeyedUnarchiver unarchiveObjectWithData:data]; snakeHead2.position = ccp([[hisArray objectAtIndex:0] integerValue], [[hisArray objectAtIndex:1] integerValue]); direction2 = ccp([[hisArray objectAtIndex:2] integerValue], [[hisArray objectAtIndex:3] integerValue]); bodyOffsetX2 = [[hisArray objectAtIndex:4] integerValue]; bodyOffsetY2 = [[hisArray objectAtIndex:5] integerValue]; amountBodies2 = [[hisArray objectAtIndex:6] integerValue]; } </code></pre> <p>This does not work and the game crashes.</p> <p>So what am I doing wrong here?</p>

    1. COTry to avoid sending "archived" data over the network frequently, that is a HUGE waste of bandwidth. Rather send a simple memory buffer with each value followed by the other (a "packet" of data). As for your question: how does it crash? Where? What does it say?

    2. COTread 1:EXC_BAD_ACCES (code=1, address=0xd0000010) Thats the error and and it chrashes directly when sendData is called.

    3. COencodedArray is not nil? snakePeers is not nil and contains NSString with player names? Try sending a newly allocated NSData with nothing in it, or perhaps just a string to see if the problem is with the data.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
