Delete an object in core data

Question

I have an entity in my core data model like this:

@interface Selection : NSManagedObject

@property (nonatomic, retain) NSString * book_id;
@property (nonatomic,

In addition to Mike Weller and flexaddicted, after calling [context deleteObject:currentObj]; you need to save: context:

NSError *error = nil;
[context save:&error];

As from documentation:

Just as a new object is not saved to the store until the context is saved, a deleted object is not removed from the store until the context is saved.

That made matter in my case.
