UINavigationBar title font size in landscape

Question

Is there anyway I can set the font size for the UINavigationBar title in landscape mode?

I'm using the UIAppearance proxy to customize the title text attributes and I am specifically interested in the font size when in landscape. It's font in portrait but when rotating to landscape the font size does not shrink as the default behaviour.

[[UINavigationBar appearance] setTitleTextAttributes:[[NSDictionary alloc] initWithObjectsAndKeys:
                                           [UIFont fontWithName:@"Awesome-Bold" size:20], UITextAttributeFont,
                                           [UIColor colorWithWhite:0.0f alpha:0.2f], UITextAttributeTextShadowColor,
                                           [NSValue valueWithUIOffset:UIOffsetMake(0.0f, -1.0f)], UITextAttributeTextShadowOffset,
                                           [UIColor whiteColor], UITextAttributeTextColor,
                                           nil]];

Unfortunately I don't see any barMetric: property to go along with setTitleAttributes: .

Thanks.

所以经过网上研究后我发现字体大小必须设置为0 ，这样可以确保字体在横向和纵向中自动设置为合适的大小：

[UIFont fontWithName:@"Awesome-Bold" size:0], UITextAttributeFont
