When I make any iOS 8 Today Extension, there is an empty space on the left of approximately 48px, even if in Interface Builder I place a label on the left side at x=0.

on xcode on the simulator

I have seen that some apps, however, use a full-width widget.

other apps

How can I achieve something similar?

Thanks!

UPDATE: SOLVED

I put here the sample code because I guess it will be useful to someone. As suggested by @matteo-lallone, the correct way to do this is:

-(UIEdgeInsets)widgetMarginInsetsForProposedMarginInsets:(UIEdgeInsets)defaultMa‌​rginInsets{
return UIEdgeInsetsZero;
}

Straight from the docs:

A Today widget created using the Xcode Today template includes Auto Layout constraints for standard margin insets. To get the inset values for your calculations, implement the widgetMarginInsetsForProposedMarginInsets: method.

    Thank you, as you suggested I added this code and the problem was solved! -(UIEdgeInsets)widgetMarginInsetsForProposedMarginInsets:(UIEdgeInsets)defaultMarginInsets{return UIEdgeInsetsZero;} – Antonio Giarrusso Sep 23 '14 at 12:50

    Your link is dead. Take this one [NotificationCenter.html](https://developer.apple.com/library/ios/documentation/General/Conceptual/ExtensibilityPG/NotificationCenter.html#//apple_ref/doc/uid/TP40014214-CH11-SW5) – Felix Sep 23 '14 at 19:54
  • Thanks @Felix, it was fine when I posted it! Updated. – Matteo Lallone Sep 24 '14 at 17:02

I can supplement the swift version

func widgetMarginInsetsForProposedMarginInsets(defaultMarginInsets: UIEdgeInsets) -> UIEdgeInsets {
    return UIEdgeInsetsZero
}

for oc 

-(UIEdgeInsets)widgetMarginInsetsForProposedMarginInsets:(UIEdgeInsets)defaultMarginInsets {
    return UIEdgeInsetsZero
}

hope it can help someone.
