Doing some research on this, it looks like you couldn\'t toggle Do Not Disturb mode in iOS 6 or 7. Wondering if you can do it in iOS 8. I can\'t find anything in Apple\'s do
Although the correct answer is "no at the moment you cannot", saying it is because of sandboxing is misleadings. Most of the things you do on iOS when you use Apple provided SDKs are basically Apple sanctioned circumventions of the sandbox.
The correct answer is, no you cannot because Apple does not allow it and has not yet published and SDK to allow this.
