  1. In Topic: (Noob) Problem with Deck of Cards Class

    Posted 16 Aug 2013

    My guess is because you are not initializing the array that holds the deck. Try creating your init method:

    - (id)init{
        deck = [[NSMutableArray alloc] init];
    }
    
    



    That should fix it.
  2. In Topic: Confusion with Calling Methods in Objective C

    Posted 16 Aug 2013

    In the second line, you rarely if ever use:

    [[NSString alloc] init];
    


    Usually if you are using alloc/init with an NSString you'd be using a method such as:

    [[NSString alloc] initWithFormat: @"%d", someNumber];
    
    .

    So you're currently just initializing to whatever the general initial value is.

    If the syntax itself is confusing you, Objective-C uses a syntax that combines C with SmallTalk. The object-based model used in these two languages uses a concept of message sends instead of methods. Within each set of [] is a message send. So

    [NSString alloc];
    


    actually sends the message alloc to NSString and returns whatever value that would be. The line

    [[NSString alloc] init];
    


    first calls this alloc method and takes the return value and sends the message init to it.

    Hope that clarifies a few things for you!

    You know, that seems to be a better solution.
  4. In Topic: A Basic PyQt Tutorial (Notepad)

    Posted 31 Jul 2013

    Huh, that's interesting. When I wrote the tutorial I had read that HOME should work just fine on Windows as well, but I didn't have a Windows environment to test it in, to be perfectly honest. I was running in Linux.... I'll have to do some research and update the tutorial if possible, thanks for pointing that out!
  5. In Topic: PYQT4 Python problem with buttons

    Posted 26 Feb 2013

    Could you please post the ui_designer code as well? It could possibly be a problem in there.
