Am I correct to believe there is NO way to use NSUndoManager.prepareWithInvocationTarget: if your undo method requires a parameter?
I can use any method I want which has no parameter, but any method with parameters gets me the error “AnyObject does not have member named…” I thought about making a ClosureWrapper object which could have a parameterless method to call any method on a captured object, but since the invocation holds a weak reference, I think any instance of ClosureWrapper would be destroyed immediately after registration, so I didn’t bother trying. Right now I’m sticking with registerUndoWithTarget:selector:object:, but I’d like to know if there is a good way to use prepareWithInvocationTarget: instead. — Charles _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
