The Bold Text accessibility feature in iOS 7 appears to have no API for detecting whether it's enabled or not.

In an app that uses custom fonts, I want to be able to set display fonts depending on whether this feature is enabled. That is, to do something like this:

    if (UIAccessibilityBoldTextModeEnabled()) {
        myTextualView.font = [UIFont fontWithName:@"Foobar-Bold" size:myFontSize];
    } else {
        myTextualView.font = [UIFont fontWithName:@"Foobar-Regular" size:myFontSize];

If such an API call does, in fact, exist, please redirect this ticket to the API Documentation team. :-)


Looks like this is now supported via UIAccessibility.isBoldTextEnabled (iOS 8+). Also toggling bold font does trigger the notification UIContentSizeCategory.didChangeNotification. Although officially the userInfo of this notification only contains the UIContentSizeCategory.newValueUserInfoKey it also includes a UIContentSizeCategoryTextLegibilityEnabledKey which as far as I can tell is undocumented. But you can still just query isBoldTextEnabled regardless.
