Hello together :)
So I have custom UIView Elements shown on top of the camera image which works fine. Now I want to set them to hidden by default and only show them, if a specific Image Target is detected. So I tried calling setHidden:NO in renderFrameQCAR but the elements don't show up. I figured that the problem is, that renderFrameQCAR runs on a background thread and the UI must be updated on the main thread, but calling the selector which updates the UI via performSelectorOnMainThread: doesn't really work either. Does anybody else know a solution for this problem? Thanks in advance!
Great to hear :)
