ios - 如何修复 UITextView (iOS) 中修改的段落样式中的垂直选择 handle ？

Question

This is the problem:

What I have done?

我已为此文本设置了段落样式:

 let titleParagraphStyle = NSMutableParagraphStyle()
 titleParagraphStyle.alignment = .natural
 titleParagraphStyle.paragraphSpacing = 33

 let attributes = [NSParagraphStyleAttributeName: titleParagraphStyle]

这当然使光标始终巨大，因此在此之后我覆盖了caretfor，一切正常，直到选择文本:

override func caretRect(for position: UITextPosition) -> CGRect {
        var original = super.caretRect(for: position)
        guard let isFont = self.font else { return original }
        original.size.height = isFont.pointSize - isFont.descender
        return original
    }

What I am missing here? How can I make the selection handles to be equal size than the text?

目前，您实际上正在更改文本的间距属性，这不可能更改选择光标的大小。您可以做的只是当您检测到 yourTextField.attributedText?.size().width 通过一定距离时，以编程方式在 textDidChange 中设置间距。我认为您没有复制和粘贴，所以这样就可以了。否则请告诉我。
