ios - 如何对齐嵌入在 UITextView 中的图像

Question

由于我的应用程序逻辑，我需要在 UITextView 中呈现一些带有图像的文本。嵌入图像不是问题(给出了工作解决方案，例如，此处 How to add image and text in UITextView in IOS? )。但我完全不知道如何对齐图像。我尝试设置属性

var attributedString: NSMutableAttributedString!
let textAttachment = NSTextAttachment()
let image = UIImage(named: imageName)            

textAttachment.image = image
let attrStringWithImage = NSAttributedString(attachment: textAttachment)

let style = NSMutableParagraphStyle()
style.alignment = NSTextAlignment.justified
let attrs = [NSParagraphStyleAttributeName: style]

attributedString = NSMutableAttributedString(attributedString: attrStringWithImage)
let text = NSAttributedString(string: myText, attributes: attrs)
attributedString.append(text)

myTextView?.attributedText = attributedString

但不影响图像。文本对齐得很好，但图像总是卡在 View 的左边缘。 如何修复它？提前致谢。

var attributedString: NSMutableAttributedString!
    let textAttachment = NSTextAttachment()
    let image = UIImage(named: yourImage)

    textAttachment.image = image

    textAttachment.image = UIImage(cgImage: (textAttachment.image?.cgImage)!, scale: 20, orientation: UIImageOrientation.left)
    let attrStringWithImage = NSAttributedString(attachment: textAttachment)

    let style = NSMutableParagraphStyle()
    style.alignment = NSTextAlignment.justified
    let attrs = [NSParagraphStyleAttributeName: style]

    attributedString = NSMutableAttributedString(attributedString: attrStringWithImage)
    let text = NSAttributedString(string: yourText, attributes: attrs)
    attributedString.append(text)

    txtView?.attributedText = attributedString

您可以使用此代码根据需要更改方向和比例。
