Code:

Card.h:

            NSLog(@"GameOver");
        }
    }
}
@end

So now i try to make a iPhone app for that, so i made a new iphone project, moved the Card,Deck and Game Classes to the iPhone project and made a High button, a Low button, and a start button to buid a new deck.

now how do i do that when i click the Start Button, it will trigger the method createDeck and CreateFullDeck that are in Deck Class?

Answer 1

First you would make Deck a declared object in your header file of, lets say your UIViewController, make sure you #import Deck.h.

#import "Deck.h"

@interface MainViewController: UIViewController

      Deck *deck;
@end

Now, you can initialize your deck in -viewDidLoad method of MainViewController

-(void)viewDidLoad {

    [super viewDidLoad];

     deck = [[Deck alloc] init];
 }

On your button action, you will create the full deck. Assuming this is an IBAction connected to a UIButton in Interface Builder;

 -(IBAction)onCreateClicked:(id)sender {

      [deck createDeck:deck];
      // You now created your deck of cards.
   }

Hope this helps !

EDIT: After investigating your code further, There are numerous things wrong with your code, but above example will do what you're asking to do.
