Trying to work through examples in the book "More iPhone3 Development". To generate the code made in the first 2 chapters, you can create a project -- a navigation application, using core data for storage. However, when I try to add string attributes to the entity already created, I get an error.
Below is the only code in the program that references any attribute --
" [newManagedObject setValue:[NSDate date] forKey
"timeStamp"];"
This is under the method "insertNewObject".
To add another attribute, I change this to
[newManagedObject setValue"" forKey"name"];
"name" is the second attribute, with type of string.
When I do this, I get the error, stating --
"The model used to open the store is incompatible with the one used to create the store"
Any thoughts why this might be happening? Thanks for any help.
