Present UIActivityViewController in a way that Adapts Correctly to Size Class Changes

UIActivityViewController

says the following:

On iPad, you must present the view controller in a popover. On iPhone and iPod touch, you must present it modally.

This does not make too much sense since we have Size Classes, and modally presented viewcontrollers adapt their appearance automatically to it (e.g. when we present something as a popover, it will by default be presented as a popover in Size Class

Regular

, and fullscreen in Size Class

Compact

).

Presenting the

UIActivityViewController

in a popover for current Size Class

Compact

(which should automatically show fullscreen) does not work, the system complains. Presenting it as a popover for current Size Class

Regular

, and then changing the Size Class via Split Mode / Multitasking results in an empty nav bar and I cannot dismiss the viewcontroller. I should notice that I embedded the

UIActivityViewController

in a navigation controller.

Any suggestions how to make this responsive?

You must not embed the UIActivityViewController in a UINavigationController. I know it doesn't say so in the docs, but that's the only way I got it to work. And then you can actually present it the same way as you would do with any other popover/modal view. And it adapts correctly when you active Split Mode while it is being presented.
