UINavigationBar titleView用于不同的方向

Question

What is the best way to resize UINavigationBar titleview content image when orientation is changed. I have one image with 44px height and another for 32px and after view is rotated I change the titleview and set new imageview. but maybe there is another way to achieve some result by autoresizingmask or some other trick?

Answer 1

The autoresizingMask can modify the size of a view's frame when the device is rotated, but if you want to switch between two different images when the rotation happens you'll have to do it programmatically in willAnimateRotationToInterfaceOrientation:duration:

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation duration:(NSTimeInterval)duration
{
    [super willAnimateRotationToInterfaceOrientation:interfaceOrientation duration:duration];

    if (interfaceOrientation == UIDeviceOrientationLandscapeRight || interfaceOrientation == UIDeviceOrientationLandscapeLeft) {        
        // landscape
        [imageView setImage:landscapeImage]; 
    } else {
        // portrait
        [imageView setImage:portraitImage]; 
    }
}
