如何在标签中添加两个NSTextAttachment？

我想在我的标签中添加2个图标。 我有两个图像：一个是鸟，一个是鸭。

我希望我的标签显示如下文字：

[鸟的形象]鸟[鸭的形象]鸭。

目前，我只知道在一个标签中实现一个NSTextAttachment 。

 let birdAttachment = NSTextAttachment() let birdImage = UIImage(named:"bird") birdAttachment.image = birdImage let birdString = NSMutableAttributedString(string: "Bird") let stringWithBirdImage = NSMutableAttributedString(attributedString: NSAttributedString(attachment: birdAttachment)) stringWithBirdImage.appendAttributedString(birdString) let duckAttachment = NSTextAttachment() let duckImage = UIImage(named: "duck") duckAttachment.image = duckImage let duckString = NSMutableAttributedString(string: "Duck") let stringWithDuckImage = NSMutableAttributedString(attributedString: NSAttributedString(attachment: duckAttachment)) stringWithDuckImage.appendAttributedString(duckString) label.attributedText = stringWithBirdImage 

那么如何在标签中添加2个NSTextAttachment 。

Answer 1

这里是对@Khuong和@ Larme的简洁的一个小调整：

 func stringForAttachment(named imageName: String, caption: String) -> NSAttributedString { let attachment = NSTextAttachment() let image = UIImage(named: imageName) attachment.image = image let fullString = NSMutableAttributedString(string: caption) fullString.appendAttributedString(NSAttributedString(attachment: attachment)) return fullString } let labelText = NSMutableAttributedString() labelText.appendAttributedString(stringForAttachment(named: "bird", caption: "Bird")) labelText.appendAttributedString(stringForAttachment(named: "duck", caption: "Duck")) label.attributedText = labelText 

Answer 2

我在评论中跟着@Larme回答。

 let birdAttachment = NSTextAttachment() let birdImage = UIImage(named:"bird") birdAttachment.image = birdImage let birdString = NSAttributedString(string: "Bird") let stringWithBirdImage = NSAttributedString(attributedString: NSAttributedString(attachment: birdAttachment)) let duckAttachment = NSTextAttachment() let duckImage = UIImage(named: "duck") duckAttachment.image = duckImage let duckString = NSAttributedString(string: "Duck") let stringWithDuckImage = NSAttributedString(attributedString: NSAttributedString(attachment: duckAttachment)) let finalAttributedString = NSMutableAttributedString(string: "") finalAttributedString.appendAttributedString(stringWithBirdImage) finalAttributedString.appendAttributedString(birdString) finalAttributedString.appendAttributedString(stringWithDuckImage) finalAttributedString.appendAttributedString(duckString) label.attributedText = finalAttributedString 

它运作良好。
