Delete objects from NSManagedObjectContext from another method

Question

I\'m trying to delete all the objects, but I can\'t seem to make it work. I know there is other questions for this kind of question, but they are not helpful. What I want is to

Answer 1

So, what have you tried so far?

As per the documentation.

Deleting a managed object is straightforward. You simply send its managed object context a deleteObject: message, passing the object you want to delete as the argument.

In other words, using a valid context you shoul say

[aValidContext deleteObject:managedObjectYouWantToDelete];

About your question, you need to

1. Setup a fetch request to grab the Fixture items
2. Loop the results (an NSArray) and perform the deletion

For example

NSFetchRequest* request = // create the request here...

NSError *error;
NSArray *array = [aValidContext executeFetchRequest:request error:&error];
if (array == nil) {
    // Deal with error...
} else {
    // loop the array performing deleteObject
}

// save to persistent store

Remaining code is left for exercise ;)

Edit 1

Reading again your question, what is the relationship between Section and Fixture? If they are separated entities, you should perform previous steps also for Sections.
