iOS builds ignore taps

Tue Jun 2 02:56:08 EDT 2020

I meant acceleratedRendering, sorry. I was talking to someone about fullscreenMode right before 
I answered you and had a think-o. I do have acceleratedRendering enabled in my app.

I also ran into the problem you described below -- taps went through but the screen did not 
redraw so the content didn't change. I had to force a screen redraw in several places using 
"set the backcolor of this cd to the backcolor of this cd". It took me hours to figure out what 
was wrong, I kept thinking it was something in my scripts.

In my case that happened when a group was shown with a visual efect, like you did. The card 
content did not change. Taps did go through but visually there was no update.

That was different from the one I started this thread with, which had no response at all. The 
script didn't run, breakpoints did not trigger. I even put a transparent button over the 
graphic to see if that would work and it didn't trigger either. This was on the first card 
shown at launch. But a field at the bottom of the card did receive a mouseup, so the problem 
was related to only part of the card. I poked around trying to find where the dead edges were 
but it didn't match any groups or controls in particular. The weird part is that it worked in 
some builds and not in others, though I never changed acceleratedRendering settings.

This could be a problem since the fields hold credentials and the graphic is a "Log In" button. 
On the bright side, it keeps users out of the app which cuts down substantially on maintenance.

I had displayed a group with a visual effect inside a rect… only controls inside the rect appeared unresponsive. When put away using  unlock the screen with visual effect, I could briefly see the selection on some radio buttons change.

There are no native controls involved -- the worst offender is a regular LC graphic that serves as a login button. Sometimes it just doesn't trigger. Other times it's a locked LC field that needs to respond with clicktext. No handlers run at all.
