UIViewController do not rotate to landscape

Question

In many situation need to rotate the controller and is not working. Right now I have the inverse of the problem: it is rotating, and I want to disable.

In that ViewContr

Answer 1

detect the Landscape rotation and rotate to Portait:

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{ 

    UIInterfaceOrientation appOrientation = [UIApplication sharedApplication].statusBarOrientation;
    float width = self.view.bounds.size.width;
    float height = self.view.bounds.size.height;
    //NSLog(@"width %3.0f, height: %3.0f", width, height);

    if((fromInterfaceOrientation == UIInterfaceOrientationPortrait || fromInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)){
        // if is rotated from Portait:
        if((appOrientation == UIInterfaceOrientationLandscapeLeft || appOrientation == UIInterfaceOrientationLandscapeRight)){
            // to Landscape:
            CGAffineTransform transform = self.view.transform;
            transform = CGAffineTransformRotate(transform, -(M_PI / 2.0));
            self.view.transform = transform;            

            [self.view setBounds:CGRectMake(0, 0, height, width)];
        }
    }
    else {
        // it is rotated from Landscape:
        if((appOrientation == UIInterfaceOrientationPortrait || appOrientation == UIInterfaceOrientationPortraitUpsideDown)){
            // to Portrait:            
            CGAffineTransform transform = self.view.transform;
            transform = CGAffineTransformRotate(transform, +(M_PI / 2.0));
            self.view.transform = transform;            

            [self.view setBounds:CGRectMake(0, 0, height, width)];
        }
    } 
}

it isn't the best programming paradigm, but it does the trick.

Somebody write similar like tis to accept his answer, or write a better method, if you can!
