Sounds like you’re getting there – just as a note, an init method should always call it’s superclass’s init method, for example

- (id)initWithContext:(CGLContextObj)context {
    self = [super init]; // Assuming super is NSObject
    if (self) {
        cgl_ctx = CGLRetainContext(context);
    }
    return self;
}
