我正在创建一个聊天应用程序,我正在插入啤酒图标的字段不会渲染图像或似乎没有内嵌渲染图像.我没有收到任何错误,所以我假设我在代码中遗漏了一些小细节.

var beername:String!        if(sender == bn_beer1)        {            beername = "beer1.png"        }        if(sender == bn_beer2)        {            beername = "beer2.png"        }        if(sender == bn_beer3)        {            beername = "beer3"        }        var attachment:NSTextAttachment = NSTextAttachment()        attachment.image = UIImage(named: beername)        var attachmentString:NSAttributedString = NSAttributedString(attachment: attachment)        var myString:NSMutableAttributedString = NSMutableAttributedString(string: inputFIEld.text)        myString.appendAttributedString(attachmentString)        inputFIEld.attributedText = myString;

这不适用于UITextFIEld.它只适用于UILabel.

这是基于您的代码的UILabel扩展(Swift 2.0)

extension UILabel{    func addImage(imagename: String)    {        let attachment:NSTextAttachment = NSTextAttachment()        attachment.image = UIImage(named: imagename)        let attachmentString:NSAttributedString = NSAttributedString(attachment: attachment)        let myString:NSMutableAttributedString = NSMutableAttributedString(string: self.text!)        myString.appendAttributedString(attachmentString)        self.attributedText = myString    }}

编辑：

这是一个新版本,允许在标签之前或之后添加图标.还有一个从标签中删除图标的功能

extension UILabel{    func addImage(imagename: String,afterLabel bolAfterLabel: Bool = false)    {        let attachment: NSTextAttachment = NSTextAttachment()        attachment.image = UIImage(named: imagename)        let attachmentString: NSAttributedString = NSAttributedString(attachment: attachment)        if (bolAfterLabel)        {            let strLabelText: NSMutableAttributedString = NSMutableAttributedString(string: self.text!)            strLabelText.appendAttributedString(attachmentString)            self.attributedText = strLabelText        }        else        {            let strLabelText: NSAttributedString = NSAttributedString(string: self.text!)            let mutableAttachmentString: NSMutableAttributedString = NSMutableAttributedString(attributedString: attachmentString)            mutableAttachmentString.appendAttributedString(strLabelText)            self.attributedText = mutableAttachmentString        }    }    func removeImage()    {        let text = self.text        self.attributedText = nil        self.text = text    }}
