问题
The iPhone 6 Plus has a "one handed mode" that Apple describes as "Keep everything within reach" on their iPhone design page.
The mode is enabled by double touching (but not pressing) the home button. When enabled the screen shrinks to roughly half its normal height.
Is there a way to enable this mode in simulator for testing how it looks and transitions?
I'm running Xcode 6 GM and have not been able to uncover anything. Worst case, can someone post the exact dimensions on device so it can be emulated via the resizable iPhone simulator?
Update: According to John Gruber's review, the feature is available on the iPhone 6 Plus and 6, and is not a "mode" so much as a momentary shortcut. Maybe since it only lasts for one tap it won't be important to do extensive testing. He shared a screenshot showing the corresponding size difference:

The simulator doesn't seem to have this capability, but it doesn't matter since it just moves your app's entire view down and uses the home screen background to fill the top. Devs don't need to do anything to their apps in regards to it.
