Creating NSMappingModel programmatically

I'm trying to create an NSMappingModel manually between two models, but it's not working in that no data gets migrated over (I checked with an SQLite database browser) to the new store, the tables are just empty. The source model has one entity Person with two attributes: name and eyeColor. Th

Any frameworks for Leopard's Spaces?

How can I make my app know about when a space has changed, and when it has done so to which space it has changed? Also, how can I read which Spaces and how many are currently available? I'm allowed to use Snow Leopard. The only thing I'm aware of is the NSWorkspaceActiveSpaceDidChangeNotificati

RE: Any frameworks for Leopard's Spaces?

I don't mind using private API for this. After all my goal is to make some simple in-house app and it doesn't matter too much if it breaks after some OS X update. I am aware the private API discussion is forbidden here. Thus, if anyone can point me in the right direction, I would appreciate it

iCal-style NSTextFields

Hi, Go into iCal (in Snow Leopard) and create a new event and and then click outside that event. Then double-click on that event and hit the "Edit" button. In the window you see, you have some neat looking text fields that show only text when not in focus but show you a white background with a

NSTextField controlTextDidEndEditing

I have a delegate of NSTextField that uses the controlTextDidEndEditing: method to do some stuff when the editing has finished. However, there are (as far as I can imagine) two types of possible scenarios under which the editing finishes: 1) the user hits return. in this case, the focus stays

Making a beta version expire

For a beta version of an app, let's say I want to make sure that users cannot use the beta for far too long, far longer than the app goes out of beta. (Note that this case would in reality rarely occur. Most users would end up getting notified of a new update far sooner. This is just a "safety"

Modeling "Smart Playlists"

How would you model "smart playlists" (like in iTunes) with Core Data? If you have a Song entity, it is fairly obvious how you model a "regular playlist". The RegularPlaylist entity would simply have a to-many relationship to the Song entity, being a simple collection of songs that the user ad

Detecting when fetch: finishes

I have an NSArrayController that, at the request of the user, can be given a new fetch predicate. To do that I use the setFetchPredicate: method. How can I detect when this predicate has been applied and the appropriate fetching is done? I have not come across any delegate method for it. I sus

It might be because Apple's way of alloc-ing the field editor on the spot may not be such a good idea. If I remember correctly, it didn't work for me. That may be the cause of your problem. So my suggestion is: Try making an instance variable for the NSTextView, and create it once in -init or
