    If you need to delete or flush all the data that exist in core data entity then use this method. Just pass the name of the Entity as a param to this method.

    -(void)flushEntity:(NSString*)entityName{

    NSFetchRequest *fetchAllObjects = [[NSFetchRequest alloc] init];
    [fetchAllObjects setEntity:[NSEntityDescription entityForName:entityName inManagedObjectContext:self.myContext]];
    [fetchAllObjects setIncludesPropertyValues:NO]; //only fetch the managedObjectID

    NSError *erors = nil;
    NSArray *allObjects = [self.myContext executeFetchRequest:fetchAllObjects error:&erors];
    // uncomment next line if you're NOT using ARC
    // [allObjects release];
    if (erors) {
        NSLog(@"Error occurred1");
    }else
        NSLog(@"Error occurred1");

    for (NSManagedObject *object in allObjects) {
        [self.myContext deleteObject:object];
    }
}

    Happy Coding
