61

62 UIAccessibility UIAccessibility is implemented on all standard UIKit views and controls so that assistive applications can present them to users with disabilities. Custom items in a user interface should override aspects of UIAccessibility to supply details where the default value is incomplete. For example, a UIImageView subclass may need to override accessibilitylabel, but it does not need to override accessibilityframe. A completely custom subclass of UIView might need to override all of the UIAccessibility methods except accessibilityframe. */
