Hello everyone, I know this has briefly been asked before, but the answer provided (just subclass the field editor), isn't really very cocoaish, and the docs are a bit lacking on this, so I'm asking again... Firstly, the problem... My app has a few places where the user searches for a

Update an existing Core Data store when the model changes?

Hello everyone. I'm currently developing a Core Data based app, which stores the results of some (relatively) computational intensive calculations as object attributes. While Core Data is great, it really annoys me that I have to trash my current persistent store whenever I make a change

Hello everyone, I raised this problem on the list in May, although I was unable to follow up in timely fashion. I've since had time to look at it again, and I see some more people have asked about adding artwork to iTunes. As Jens suggests, an ID3 framework

Cropping an NSBitmapImageRep to a given NSRect?

Hello everyone, I can't seem to get this to work, yet it seems like it should be so easy. I have an NSBitmapImageRep, and I want to crop it to a given NSRect. The code I've attempted so far is this: // Create an NSImage for the current image rep NSImage *source = [[NSImage

Re: Cropping an NSBitmapImageRep to a given NSRect? [Solved]

Re: How to store NSRect as Core Data attribute?

Thanks for the feedback on this. I have gone with using a ...AsString attribute and using NSRectFromString. Seems to work okay, although I've got no idea if it's the most efficient method. I think Core Data seems a little limited in that you can't store an NSValue object as an attribute,
