auto resize height of UIToolbar in landscape orientation

Question

I've got a custom UIToolBar which doesn't adjust it's height to match the navigationbar on the top of the screen when I rotate to landscape mode. The height stays the same which makes it look a bit weird. The default toolbar from the UINavigationController actually reduces in size when rotated to landscape (unfortunately I can't use it because of push/pop transition issues). The current resizing mask is :

[ customToolbar setAutoresizingMask: ( UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin ) ];

If I add "UIViewAutoresizingFlexibleHeight" strange things happen...so I'm not quite sure if I should use this.

Please let me know if anyone knows the correct way to auto resize/rotate the UIToolBar to match the navigationbar height.

Answer 1

If you need to resize your custom toolbar with the same aspect ratio as standard navigation bar you should implement willAnimateRotationToInterfaceOrientation controller method like this:

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    CGRect navigationToolbarFrame = self.navigationController.navigationBar.frame;
    CGRect customToolbarFrame = CGRectOffset(navigationToolbarFrame, 0.0, navigationToolbarFrame.size.height);
    [UIView animateWithDuration:duration animations:^{
        self.customToolbar.frame = customToolbarFrame;     
    }];
}

The easiest way to achieve that is to create a UINavigationcontroller and present it as a modal view, I use something like this:

NewViewController *f = [[NewViewController alloc]initWithNibName:@"NewView"
                                            bundle:[NSBundle mainBundle]];
self.newViewController = f;

[f release];

UINavigationController *navigationController = [[UINavigationController alloc]
                           initWithRootViewController:self.newViewController];

 [self presentModalViewController:navigationController animated:YES];

Since you're presenting the view as a navigatiocontroller you can use the toolbar property.

Not sure about masks, but you can resize the view in -willRotateToInterfaceOrientation:duration:. Simply change the frame there to suit your needs. You can also do it in -willAnimateRotationToInterfaceOrientation:duration:
