ios - 带有表情符号设置的UITextView.text:cursorPosition不正确

在这里，str包含表情符号，并且设置cursorPosition不正确:

  let cursorPosition = str.characters.count
  let cursorRange = NSRange(location: cursorPosition, length: 0)
  textInputView.selectedRange = cursorRange
  textInputView.scrollRangeToVisible(cursorRange)

最佳答案

看起来您想将光标放在textView的最后。这样尝试。

textInputView.becomeFirstResponder()
let cursorPosition = str.utf16.count
let cursorRange = NSRange(location: cursorPosition, length: 0)
textInputView.selectedRange = cursorRange
textInputView.scrollRangeToVisible(cursorRange)
