Hello,
I am having a problem with toolbars. I have created a delegate class
for my toolbar, but when I added the
toolbar:itemForItemIdentifier:willBeInsertedIntoToolbar: method it
crashes:

It looks like your delegate method is returning nil. You can't return
nil from itemForItemIdentifier:.
I suppose that the bool used in the routine will be mapped to a long,
is that it? What is the adequate type encoding for a bool in
Objective-C? The docs says nothing about this.
BOOLs are signed char.
