Property 'layer' not found on object of type GLKView

Question

Property 'layer' not found on object of type 'ViewController * where ViewController is of type GLKView and also I am importing following files in my opengl project

QuartzCore/QuartzCore.h

OpenGLES/ES2/gl.h

OpenGLES/ES2/glext.h

Code for ViewController.h

@interface ViewController : GLKViewController

{

    CAEAGLLayer* eaglLayer;

}

@end

ViewController.m

@interface ViewController ()

@property (nonatomic, strong) EAGLContext *context;
@property (nonatomic, strong) GLKBaseEffect *baseEffect;

@end 

@implementation ViewController

- (void)viewDidLoad
{
 [super viewDidLoad];
 // Do any additional setup after loading the view, typically from a nib.
 self.context = [[EAGLContext alloc] initWithAPI: kEAGLRenderingAPIOpenGLES2];
 GLKView *view = (GLKView *) self.view;
 view.context = self.context;
[EAGLContext setCurrentContext:self.context];

}
+ (Class)layerClass
{
   return [CAEAGLLayer class];
}

- (void)createLayer
{
 eaglLayer = (CAEAGLLayer *) self.layer;
 eaglLayer.opaque = YES;
}

Please tell what am I doing wrong?

You need to refer to the view, not to the controller.

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

should work.
