iPhone Title and Subtitle in Navigation Bar

Question

In my application, I\'d like to have the navigation bar display a title and subtitle.

To that extent, I added the following code to my view controller:

Answer 1

Make the titleView and subtitleView labels into properties of the view controller, so that you can access them from any method. Then, on rotation of the view controller, resize the labels:

- (void) willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
    [self adjustLabelsForOrientation:toInterfaceOrientation];
}

- (void) adjustLabelsForOrientation:(UIInterfaceOrientation)orientation {
    if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight) {
        titleView.font = [UIFont boldSystemFontOfSize:16];
        subtitleView.font = [UIFont boldSystemFontOfSize:11];
    }
    else if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown) {
        titleView.font = [UIFont boldSystemFontOfSize:20];
        subtitleView.font = [UIFont boldSystemFontOfSize:13];
    }
}
