I'd like to thank all the people that contribute to this website. I am one h*ll of a noob at programming and you all help me out so much. With that said, let's get on with my latest problem!
I am creating an app that uses a UIManagedDocument to store a Core Data model for me. I use to create the UIManagedDocument with the following code, but now with Xcode 4.3.2 (The one that updates with the Mac App Store) I have an issue.
Here's the code:
NSURL *url = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
url = [url URLByAppendingPathComponent:@"MyFile"];
NSLog(@"\n\n This line does print. \n\n");
UIManagedDocument *document = [[UIManagedDocument alloc] initWithFileURL:url];
NSLog(@"\n\n This line does not print \n\n");
I receive an error in the console that goes like this:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Can't merge models with two different entities named 'Foo''
Here's the thing, I'm not trying to get versions or anything like that to work. I'm simply creating a data model with two types of entities, and trying to get a UIManagedDocument to open in my app: super simple, right?
I have uninstalled Xcode and reinstalled it to no luck. I have also deleted my Core Data Model and redone it from scratch with no luck.
I am completely lost and have already spent about 2 nights trying to troubleshoot this.
Help me! Please! Thanks for reading. If you need anymore information let me know. I'll give you my soul for an answer...
So I figured it out.
I had a hard time believing that I had to subclass UIManagedDocument. Ultimately I didn't' have to. I had some problems with the way my files were linked to the project.
I followed the steps here and it's all good now
