Gettin my app to autorotate

You can be informed of the Device Orientation Changes, then you'll have to manage the layout and drawing of your view according to the interface orientation

You have to activate the Device Orientation notifications

UIDevice *device = [UIDevice currentDevice];
[device beginGeneratingDeviceOrientationNotifications];

Then you have to subscribe to these notifications, for example :

[[NSNotificationCenter defaultCenter] addObserver:self
 selector:@selector(orientationDidChange:)
 name: UIDeviceOrientationDidChangeNotification
 object:nil];

Try

-(void)setViewToLandscape:(UIView*)viewObject {
 [viewObject setCenter:CGPointMake(160, 240)];
 CGAffineTransform trans = CGAffineTransformMakeRotation(-M_PI/2.);
 viewObject.transform = trans;
 viewObject.bounds = CGRectMake(0, 0, 480, 320);
}

Sorry if I missed it...is this iPhone or iPad?

Did you miss my reply on the Dev Forums yesterday?

-dupe-

I understand your question 🙂

Replace your existing similar code with the lines I suggested and try it before you give up. I'd like to know if that fails as well before suggesting something different.

What code have you tried that failed?

OK. I am assuming that you are using the OpenGLES Template iPad application to start your project. Why Apple choose to make it look like it does is beyond me, but there you go.

What you need to do is start a View based application, and then copy in the opengl parts of the opengles template project into the view based project. Then in the ViewDidLoad function, you need to create an instance of your OpenGLES View (EAGLView or something like that). You then have an autorotating OpenGLES project. Yay.

There are other issues with doing this, but with a simple project it should be fine. If, like me, you want to run the OpenGL updates in a thread, it then becomes a world of pain, with everything being initialised at the wrong times and crashing in openGL functions etc.... but for what you are doing, this will work perfectly !

Haven't got the code to hand at the moment, but if you look on the web, there should be examples like this.
