Some code I just wrote to implement history menus for my browser’s back and
forward buttons:
[[backForwardList backListWithLimit:(int)maxMenuLength]
enumerateObjectsWithOptions:NSEnumerationReverse usingBlock:^(WebHistoryItem
*obj, NSUInteger idx, BOOL *stop){
The type of “obj” was originally “id,” but I changed it to what I knew the
NSArray object actually held. The compiler accepted it. Can I change any block
parameter, or only ones that are Objective-C objects? (For example, would
changing the type of “idx” or “stop” cause errors?) What happens if I use the
wrong Objective-C type?
