You know how in accessibility, the user can set the home button to triple-click and make that the "inverse color mode"? Is there a way for your app to detect if the phone is in the inverse color mode? Thanks.

You can invert all the colors on your iPhone using the Accessibility menu in the Settings app. There are two ways to invert your iPhone's colors: Using Smart Invert, or Classic Invert. If you set up an Accessibility Shortcut, you can quickly turn on inverted colors by triple-clicking the Power button.
Since there are two options for inverting colors on iPhone, you'll want to try each version—Smart Invert and Classic Invert. Smart Invert reverses colors on the display except for images, video, and other features (as seen below). Meanwhile, the Classic Invert reverses all of the colors on your iPhone screen.
In the "Accessibility" menu, under "Display," find the switch labeled "Color inversion" and toggle to the on position. 4. If your phone has the ability to do so, pull up the notification center at any time and tap "Invert colors" to turn color inversion on and off.
Yes, and it's simple. You can call
UIAccessibilityIsInvertColorsEnabled();
which return a BOOL for whether or not inverted colors is currently on.
You can also observe
UIAccessibilityInvertColorsStatusDidChangeNotification
to get notified when the user turns on or off inverted colors.
