What do you guys use for input with Cardboard and IOS?

I'm building a VR Viewer and on android there are plenty of options for input remote, leap motion, etc. For IOS I see no way to simulate a click? unless the person physically touches the screen.

I see two ways around the issue:
1. You brilliant set of people recommend hardware solutions or remotes that do this.
2. Change the entire game to time-based selection (onEnter, onExit, Timer based selection) If this is the best solution are there any helpers or examples out there?

I've done similar things with Kinect and NUI development but this is my first IOS cardboard app. Any help is appreciated even "Hey dummy, buy this" answers!

 

I would stick with Cardboard Viewer 2015 until Daydream releases, the trigger button should work with iPhone:

Thanks Selzier,
I love your videos BTW it's really the only source for VR help out there right now.
I have a regular cardboard viewer but bought a V2 plastic box and love it... only thing, it doesn't have the hardware trigger.
