Question

I am trying to add a variable amount of MenuItem objects to a Menu object on runtime. When my game starts I don’t really know if my menu is having 2 or for example 5 items.

for (MyItem* item in myItemCollection)
{
        MenuItemImage* menuItem = [MenuItemImage itemFromNormalImage:@"MenuItem.png" selectedImage:@"MenuItemSelected.png" target:self selector:@selector(options:)];
}

How do I now add the MenuItems to a Menu object. By using addChild I get an exception and I can’t really find a solution online.

Also, a side-question: When I can add my MenuItem’s this way. How can I get my MenuItems back and change the image they are displaying?

Answer 1

From NSMenu:

    - (void)addItem:(NSMenuItem *)newItem

Assuming you have an NSMenu object to send this message to and the MenuItemImage is a subclass of NSMenuItem.

To get you menu items back, depending on what you know about the item you have:
– itemWithTag:
– itemWithTitle:
– itemAtIndex:

Or you can iterate through the items using:
– numberOfItems
– itemArray

Check out the NSMenuItem documentation for getting/setting the image.
