[openGL] setDrawabaleProperties issue inside UIViewController

Whitehk · 01-23-2011, 02:50 PM

Hello,

I wanted to put my EAGL layer context inside a UIViewController (instead of a regular UIView as per the sample apps) as follows:

Code:

- (id)init {

     if (self      = [super init]) {

          

// Get the layer

          CAEAGLLayer *eaglLayer = (CAEAGLLayer*) self.view.layer;

          

          eaglLayer.opaque = YES;

          eaglLayer.drawableProperties = [NSDictionary dictionaryWithObjectsAndKeys:

                                                  [NSNumber numberWithBool:FALSE], kEAGLDrawablePropertyRetainedBacking, kEAGLColorFormatRGBA8, kEAGLDrawablePropertyColorFormat, nil];

          

context = [[EAGLContext alloc] initWithAPI:kEAGLRenderingAPIOpenGLES1];

          

          if(!context || ![EAGLContext setCurrentContext:context] || ![self createFramebuffer]) {

               [self release];

 returnnil;

          }

          

          [self setupView];

          [self drawView];
          

     }

     

 returnself;

}

All i did was change some self.layer to self.view.layer

It built with no errors but then I get a crash with the following message:

2011-01-23 14:43:24.791 MyApp[36059:207] -[CALayer setDrawableProperties:]: unrecognized selector sent to instance 0x4b37cd0
2011-01-23 14:43:24.793 MyApp[36059:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[CALayer setDrawableProperties:]: unrecognized selector sent to instance 0x4b37cd0'

I've been searching around but haven't been able to resolve this; can anyone help out? Thanks.
