I have an ObjC++ code for iOS. (It has, UI elements comes from c++ code). I would like to support VoiceOver. Could somebodyshow me some examples about the VO interfaces? I have found some documentation about VO (https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/MobileHIG/VoiceOverAccessibility.html) but I didn't found the developer documentation about the programming of VO module. I do not really know how to start this.
I have read this article: Can I support VoiceOver in my Cocos2D-iPhone Game? but it is still not clear for me.
How can I send VoiceOver if it is a button or a switch, or anything else?
How can VoiceOver highlight the button on the UI?
How can it read the labels of the widgets?
