Question

I have a custom UIViewController, which is the only subView of UIView. The UIViewController contains delegate function:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return YES;
}

This function is called once when the application starts and is never called again when the device is rotated. I also notice that the willRotateToInterfaceOrientation function is never called. I pretty much commented out all the content in the UIViewController but it is still not responding to device rotation.

Answer 1

I ended up solving my own problem by starting from stretch to create a brand new UIViewController and made sure it was responsive to the device rotation. I then brought in my code piece by piece and checked the rotation. In the end, I found the root cause. In my custom UIViewController, I had

- (id)initWithFrame:(CGRect)theframe {
    if (self.view = [super.view initWithFrame:theframe])

It worked find excpet it did not respond to device roation even though I did not call the init function. The solution is simple. Add [self init] in the initWithFrame function. Thank you all for responding.
