Please don't commit commented-out code. Reference a bug in a comment if you need to.

Should this use -isEqual:?

Ditto.

Each initialization on its own line please.

This must have been inadvertent. It makes the following section meaningless.

>> +        if (action && action != [NSNull null]) {

It should probably just get reversed to:

if (!action || [action isKindOfClass:[NSNull class]])
    ...disableActions...
else {
    ...other stuff...
}

I'm curious, however, why the `action` doesn't seem to be used inside the following block:

> Source/WebCore/platform/ios/WebVideoFullscreenInterfaceAVKit.mm:626
> +            [CATransaction setAnimationTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
> +            [CATransaction setAnimationDuration:0.4];

Shouldn't we be matching the timing function and duration with that of the action?

Removed. Code, referenced radar.

NSNull is a singleton, so this is valid, but I'll change it to -isEqual:

Removed imports. Created BackBoardServiesSPI.h

Removed import. Added interfaces to UIKitSPI.h

Moved to separate line.

Removed commented out code. Referenced a radar.

Intentional. I'll remove that code also and put it in the radar. The commented out code causes big UI problems. Still need to find a better way to do that.

Reversed.

That action is a private class from UIKit and doesn't lend itself to proper inspection. I'm still looking for a better way to do that.

I'll remove this code and move it to the radar.
