How to sort smoothly when NSTableColumn's Sort Key is empty

I know how to sort items in NSTableView when each NSTableColumn corresponds to a property of the item object. But what if there is only one NSTableColumn and it is just mapped to the item object itself instead of a property of it? I set the Selector to "compare:" and leave the Sort Key to empty for

Why can't I name a property `tag'?

I have a NSString * property named `tag' in my class Foo, and use Foo instances to populate an NSOutlineView. In one delegate method of NSOutlineView, I pass the `tag' property of an item to a method as an NSString * argument as follows: - (void)outlineViewSelectionDidChange:(NSNotification *)a

Any good advice for naming parameters of init methods?

I've been always stumbling on the embarrassment of "warning: local declaration of 'xxx' hides instance variable" for my init methods, because I really can't figure out a nice naming pattern for parameters used to assign to instance properties, and I am always apt to write code like this: - (id)ini
