Creating a dynamic quantity of objects

[ChrisNZ]

Hi, I am trying to create a deck of cards (which itself is just a plain image) and when the user taps this deck, a new custom "Card" object is created. The "Card" object has a UIImageView along with some NSStrings which contain the card's type, suit etc...

How would I be able to create a new "Card" object for every tap of the deck? I do not know how many cards the user will want to draw from the deck so I cannot declare them in the .h file.

Thanks in advance

You can store them all in an NSArray; that's a list of objects. This list can be of any length. The kind you want is probably an NSMutableArray; that's a mutable list that you can add and remove items from.

// make a pointer to an NSMutableArray, probably in your .h file
NSMutableArray *cardList; 

//Create the empty list and point the pointer
cardList = [[NSMutableArray alloc] init];


//create a card 
CardClass *myCard = [[CardClass alloc] init];

//put the card in the array (it gets retained by the array)
[cardList addObject:mycard];

//now we can release the card; it's safe in the array.
[myCard release];

You can get the cards back out by checking [cardList count] and calling [cardList objectAtIndex: n ];
