Question

How are toolbar items deactivated/activated?

I would like to make a few buttons visible but not selectable. How is this done if the toolbar items are set as follows.

NSArray *items = [NSArray arrayWithObjects: shareButton, space, copyButton, space, deleteButton, nil];

[self setToolbarItems:items animated:NO];

I want to activate/deactivate the share, copy and delete buttons when no items are selected.

How are these items accessed?

There are two ways that spring to mind:

1. UIBarItem has a property on it, tag, that you could set as different for each of the items you want. Then, when you need to enable/disable one of the items, get the items array, find the one with the appropriate tab then enable/disable it.
2. You could just have some ivars, each one pointing to a different button. When you need to enable/disable one of them, just use the ivar to get at it.
