我正在做一个简单的游戏并遇到了一个问题.我收到此错误:

@property (strong, nonatomic) EAGLContext *context;

- (void)setupGL;

@end

@implementation ViewController

- (void)viewDidLoad

    view.context = self.context;
    view.drawableMultisample = GLKViewDrawableMultisample4X;
    view.drawableStencilFormat = GLKViewDrawableStencilFormatNone;
