iPhone accessibility on button with image

Anyone knows how to prevent VoiceOver from speaking the button image filename?

开发者_如何转开发

Thanks in advance!

self.button.accessibilityLabel = @"Your accessibility label";
self.button.accessibilityTraits = UIAccessibilityTraitButton;

Hope this help

If you set an accessible name for the button, Voiceover will read that instead of the filename. find exact info at http://developer.apple.com/accessibility
