Summary: The tap that makes the UITextView become first responder causes UIKeyboardWillShowNotification to get posted -- but before UITextView has updated its selectedRange property. This is a problem because you might want to scroll the UITextView to show the selectedRange -- you might want to make sure the typing is visible to the user. (See #15148548: UITextView doesn't scroll to show typing.) If you get the selectedRange on the next turn of the run loop, it will be accurate -- but you won't be able to properly sync your scrolling animation with the animation of the keyboard appearing. Steps to Reproduce: See the attached project that demonstrates the bug. Expected Results: selectedRange is correct when UIKeyboardWillShowNotification is posted. Actual Results: selectedRange is not correct when UIKeyboardWillShowNotification is posted. Version: iOS 7 Attachments: 'TVKeyboardSelectionBug.zip' was successfully uploaded.
