iOSToolButton Misfire

I’ve seen this a couple times and I don’t know how to get it to stop.
For some reason if I tap anything in my view one of the tool buttons fires.

Anyone see this before?

Nope.

Is it a Toolbutton placed in navigation bar or in the toolbar?

do you create it by code or by dragging in the layout editor?

apparently quitting the simulator and restarting it solved it. Very strange.
