How do I push a view controller once an image tracker is recognized?

By Supereid86 on Wed, 06/20/2012 - 17:11

How do I push a view controller once an image tracker is recognized? Where do I call [self presentModalViewController: ] from? I want to recognize an image, and push a view controller with my own views in it. I can show a view, by adding my own view as a subview in EAGLView's render method, but I need an entire view controller to be shown.

@MOSR, my question had more to do with the workings of the EAGLView view. When it recognizes a marker image, it calls renderFRameQCAR, and whatever code gets put in there will get called, as long as the marker is on screen.

In the render method I added the following code: if ((trackable->getStatus(), "DETECTED")) { [self.delegate EAGLView:self didRecognizeMarkerAtIndex:targetIndex]; } The problem is that this gets called like 60 times/second, as long as the tracker is on screen.

Hi Supereid86, This is an app logic design problem not a QCAR issue.

@MOSR Using pauseAR before the delegate receives the message and resumeAR after popup is dismissed solved my problem, as the AR stopped looking for tracking markers. Thanks!

That's good Supereid86 - but take heed of the first item as well: "If you want to invoke a pop-up screen on only the first detection, you need to set up the logic to do that." It could be possible to get a second 'frame' after detection causing another attempt to pop-up a modal view, before pauseA
