Ah, so when it says "the method must derive the reference object from the
managed object’s values" it is talking about the managed object's persisted
values. So I could get rid of my extra attribute in my managed object class and
just set my UUID using a method similar to what you define below,

Excellent, thanks for that. I thought that once a managed object ID had been
assigned, that newReferenceObjectForManagedObject: should always return the
same value, so I was regenerating it from the previous data instead of
generating a new one if it either had a temporary object id or no object

No, an outlet is a single variable that can point to only one object at a time.
(You can't use NSArrays as outlet values.) you'll need multiple outlets, or one
view you move between two superviews.

Ken, he asked for a reference that wouldn't break if the file were moved or
renamed. Neither FSrefs nor URLs have that property.
Brad, what you want is a bookmark (in 10.6) or an alias reference. Aliases
didn't have a Cocoa API until 10.6, but the procedural API isn't hard to use.

Phew, that's a relief. I'll look forward to hearing what I'm doing wrong in my

I have I'm afraid led you astray. The invalidated objects are not coming from
the Save As operation
Wow, this is huge! Obviously the user doesn't expect the document to disappear
and a new one open up just because they did a Save As operation, so I would
have to go through every single part of the application, work out every
reference to a managed object, and either throw them away or fetch ne
Very interesting. According to the documentation if I want to store the
reference and want it to persist after a reboot I need to do a bookmark.
You should not store or archive file reference URLs. A file’s ID may be
different for different boots of the operating system. If you need to store

The main issue with the original code is that it assumes that the value is a
CGPoint. If it were anything smaller, you'd get garbage values in your point,
and if it were any larger, you'd be stomping on memory as you ran off the end
of your CGPoint variable.
Any time you use -[NSValue getValue:
Thanks
pointValue didn't work on iPhone OS but CGPointValue did, luckily, as that's
the one I needed. That seems to be a UIKit extension. I've switched to that.
was my original method (apart from being clunky) wrong? It did work.

I have a property which is a CGPoint and I'm observing it. I didn't really know
what to expect in the change dictionary (I have NSKeyValueObservingOld as the
observation flags) so I stuck in a breakpoint and went looking. After messing
about in the debugger when the property was changed I found
I found it:
The .h was @interface AdresViewController : UITableViewController.
I changed this to @interface AdresViewController : UIViewController and it now
does work...

Can anybody help me understand how namespaces works with NSXMLNode etc. There
is the method
+ [NSXMLNode elementWithName:(NSString *)name URI:(NSString *)URI]
Which takes an namespace URI, but doesn't seem to use it. I have seems an
example from google where they pass the namespace URI and th
