Remarks
After the application user has set the "Text Size Property" in Settings, the application will receive a notification via ObserveContentSizeCategoryChanged(EventHandler<UIContentSizeCategoryChangedEventArgs>). It is the application developer's responsibility, at that point, to invalidate the layout in all view elements that implement Dynamic Type. The simplest way to do that is to have a method that re-sets the font in all components that support Dynamic Type:
UIApplication.Notifications.ObserveContentSizeCategoryChanged((s,e) => {
SetDynamicTypeFonts();
});
//Call this when initializing, and also in response to ObserveContentSizeCategoryChanged notifications
private void SetDynamicTypeFonts()
{
headlineLabel.Font = UIFont.PreferredFontForTextStyle(UIFontTextStyle.Headline);
bodyText.Font = UIFont.PreferredFontForTextStyle(UIFontTextStyle.Body);
//...etc...
}
