UITextView did finish change selection

Question

I want to catch event when user finish change selection in UITextView. Method textViewDidChangeSelection: call a few times while user pulls cursor. I try to use touchesEnded:withEvent: , but it doesn't call. Try to add pan gesture, but pan handler don't call.

Answer 1

I know it's too late to answer. Though.. You can use selectedRange inside textViewDidChangeSelection: and check if selectedRange.length is greater than zero. This will confirm that user has selected something and not just moved the cursor.

Answer 2

UITextInputDelegate 's selectionDidChange(_:) is called when the user has finished changing the selection (lifts their finger from the selection handles). On the UITextView , set your class as the inputDelegate . This works for read-only text views, not just editable ones.

Answer 3

我认为你必须touchesEnded:withEvent: UITextView并实现touchesEnded:withEvent:以便知道用户何时停止更改选择。
