我已经关注了这个问题,但没有解决我的问题。

我有一个tableviewViewController ,tableviewcell有一个标签。我想attributedStringNSStrikethroughStyleAttributeName. 如果我将完整的字符串设置为删除线,它可以工作,但如果我设置为部分字符串,它就不起作用。

下面是成功结果的代码

let strOriginalPrice = "my price"
let strdiscountedPrice = "discounted price"
let strPrice = strOriginalPrice+" "+strdiscountedPrice

let attributeString: NSMutableAttributedString =  NSMutableAttributedString(string: strPrice)
 attributeString.addAttribute(NSStrikethroughStyleAttributeName, value: 2, range: NSMakeRange(0, attributeString.length))

cell.lblPrice.attributedText = attributeString 

下面的代码不起作用

let attributedDiscunt: NSMutableAttributedString =  NSMutableAttributedString(string: strPrice)
            attributedDiscunt.addAttribute(NSStrikethroughStyleAttributeName, value:2, range: NSMakeRange(0, strOriginalPrice.characters.count-1))

cell.lblPrice.attributedText = attributedDiscunt

尝试这个,

   let strOriginalPrice = "my price"
    let strdiscountedPrice = "discounted price"
    let strPrice = strOriginalPrice+" "+strdiscountedPrice

 //        let attributeString: NSMutableAttributedString =  NSMutableAttributedString(string: strPrice)
//        attributeString.addAttribute(NSStrikethroughStyleAttributeName, value: 2, range: NSMakeRange(0, attributeString.length))

    let attributedDiscunt: NSMutableAttributedString =  NSMutableAttributedString(string: strPrice)
    attributedDiscunt.addAttribute(NSStrikethroughStyleAttributeName, value:2, range: NSMakeRange(0, strOriginalPrice.characters.count-1))
    attributedDiscunt.addAttribute(NSBaselineOffsetAttributeName, value: 0, range: NSMakeRange(0, strOriginalPrice.characters.count-1))


    cell.lblPrice.attributedText = attributedDiscunt
