UIView does not respond to selector renderFrameQCAR

December 18, 2014 - 2:30am #1

My app is all but done ready to go and the last thing I would like to resolve before submitting is this error that I get when entering ARCamera mode and is repeated each time device rotates.

 

This is on IOS and although the app appears to run OK seeing this warning makes me wonder is there something I am missing....

Hi all

this is fixed in Vuforia 4.0;

also when using Unity 4.6.3, make sure to adjust the iOS Player Settings as follows:

- set the Graphics API to OpenGL ES 2.0

- set the Scripting Backend to: IL2CPP (instead of "Mono (2.x)" which is the default)

- set the Architecture to : Universal

if for some reasons you are temporarily unable to migrate to 4.0,   a workaround for 3.0.9 is to use the camera background rendering approach of the Background Texture Access sample.

I'm having the same issue. At first there was only black camera frames...setting to Open GL ES 2.0 makes the camera images appear in the bottom left quadrant of the ipad screen only. Frustrating!

It seems that you have a different problem. For me the problem was the black screen.

I'm using Unity 4.6.3, Xcode6 and vuforia 4.0 Beta.

As stated here: https://developer.vuforia.com/forum/vuforia-40-beta/camera-not-opened-and-screen-black-vuforia-40-beta

Changing Graphics API to Open GL ES 2.0 in Unity Player Settings solves the problem.

Same issue here: the screen stays black and Xcode says "Could not find a UIView with CAEAGLLayer layer class that responds to selector renderFrameQCAR".

I also tested with the Vuforia-ImageTarget scene from Vuforia samples. The GUI part is shown correctly, but the camera is black.

Running from Unity Editor is OK.

Unity 4.6.3f1 free license

Vuforia 3.0.9

XCode 6.1.1

Device: iPad Mini 2 iOS 8.1.3

Target iOS version: 7.0
