Update to iOS SDK 4.2. There are several distortions in my application (another one is asked here ). The one I want to ask for your help relates to the OpenGL view (a subclass of EAGLView), which no longer makes the 3D model that I am inserting.
The view is highlighted and it recognizes the gestures, but its contents are not visible (I checked it about the view, and not about the incorrect placement of the model, coloring the background: it does not color it through glClearColor()).
When I touch it twice, it should resize (it goes into full-screen mode, before that a bit of UIVIew), which calls this method:
- (void)animateToGrow{
DNSLog(@"grow");
grow = YES;
oldFrame = self.frame;
oldCenter = self.center;
[UIView beginAnimations:@"MoveAndStrech" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationBeginsFromCurrentState:YES];
self.frame = CGRectMake(0, 0, WIDTH, HEIGHT);
self.center = CGPointMake(CENTER_X, CENTER_Y);
[UIView commitAnimations];
[self setupGLPerspectiveNear:0.1 far:1000];
}
and a magic model appears, and even the background becomes colored.
