可访问性accessibilityDecrement（）未得到调用 [英] Accessibility accessibilityDecrement() not getting called

问题描述

为什么在执行适当的手势时在我的自定义UITextView中没有调用accessibilityDecrement（）和accessibilityIncrement（）？

Why are not accessibilityDecrement() and accessibilityIncrement() getting called in my custom UITextView when performing the appropriate gestures?

class CustomTextView: UITextView  {

   required init?(coder aDecoder: NSCoder) {
      super.init(coder: aDecoder)
      accessibilityTraits = accessibilityTraits | UIAccessibilityTraitAdjustable
   }

   override func accessibilityDecrement() {
      print("Decrement")
   }

   override func accessibilityIncrement() {
      print("Increment")
   }
}
