Core data and Today Widget

Question

Hello I have an application that calculates the usage of your internet connection (read data transfer, roaming data, wifi...). I'm trying to update it with a Widget. The first part of the app, reading the values from the database and showing them on the widget works perfect, but the values are updated only when the host app is open. I want that the widget save data to the database too, I have read a lot about context conflicts and tried to solve it, but nothing work for me. Here you have my code:

TodayViewController.h

@interface TodayViewController : UIViewController //<CLLocationManagerDelegate>

Almost all these methods come from AppDelegate:

Thanks in advance.

Finally I removed the option of save records from widget. What I do is update visually the widget with local data, and let all the "save to database" work to the host app.
