    I am starting with some graphic applications and I have a few questions. I have some experience with iphone programming but not with mac so I have so trouble with some things.

    Firs is how to create a view to actualy display something. I was looking at some source code that works and I tryed doing the same thing in interface builder but I can't get my view to show up. I allways get "app terminated with signal 5" from te debugger. And I can't figure that out.

    The second one is when you have a view and after some action you want to load another view. I do that like this:
    pogled_main *pogled = [[pogled_main alloc] initWithFrame:[self bounds]];
    [super addSubview:pogled];
    [pogled release];
    What I don' know is how to release the current view. Or I can just let the garbage collector do its work?

    The third one is how to load vector images into a NSRect? Can NSImage be used for this? because I need to resize the image based on the screen resolution and I think that the best way to do that is by using vector graphics - If I can do that which formats are supported?

    And the last one - where to get some tutorials for core graphics? I found this: Anything else/better?

    Do a search for "drawRect:" --that's where the magic happens for drawing code. Also you will probably want to read the official Apple Docs.
