Just getting started with cocoa.
Attempting to create a Core Data application "by the book".
The Core Data Programming Guide expressly recommends against this:
"Core Data is not an entry-level technology. It leverages many other
Cocoa technologies, including memory management, key-value coding, and
key-value observing. You must understand these technologies to use
Core Data effectively. You also need a solid understanding of data
modeling and the model-view-controller design pattern as it pertains
to Cocoa."
You should wait until you have completely mastered issues such as the
following before you undertake development of a Core Data-based
application.
In the run log I can see that my action is being triggered when I
press the button, but the text field remains empty.
What am I doing incorrectly?
There are several things you might have done incorrectly, the first
being that you didn't actually make (or save) the connection. Is the
name of the outlet in IB the same as the IBOutlet instance variable?
Are there any runtime errors? How did you implement your action method?
