Getting warning when saving merged MOC

I'm slowly but surely getting the hang of using multiple MOCs. I'm successfully creating objects in MOC B and merging those changes into the existing MOC A, and seeing the UI bound to MOC A update to reflect the changes. The problem I'm seeing now is that MOC A then becomes dirty, and wants to b

One idea would be to draw the text into the view at the normal angle, then convert the contents of the view into an NSImage, put that into an NSImageView and rotate that instead. I'm not sure how good of a solution this is, or if there is a better solution, but I've found that manipulating image

Thank you to all who offered your expertise! Whatta dumb mistake! I thought all objects were retained once when created, not auto-released. Gah! I've been programming for 20+ years--mostly with C++ and C#. Cocoa-ObjC has the steepest learning curve of any programming I have ever done. It mak

Simple Core Data problem - zombie objects left in store

Hi folks & Happy New Year, I'm not sure why this is a problem as I've done this before now, so can't quite see the problem. This is all on 10.6.2 in a Core Data app (i.e. non-document-based). Despite re-reading the Core Data Programming Topics & Marcus Zarra's (excellent) book, I'm stumped
