Question

我使用以下代码来浏览文本

NSMutableAttributedString *attributeString = [[NSMutableAttributedString alloc] initWithString:(text ? text : @"")];
[attributeString addAttribute:NSStrikethroughStyleAttributeName
                        value:@2
                        range:NSMakeRange(0, [attributeString length])];

label.attributedText = attributeString;

文字为白色，因此删除线也是白色。我想把它改成红色。我怎么能这样做？

Answer 1

根据NSAttributedString UIKit Additions Reference，您可以设置

NSStrikethroughColorAttributeName

属于您选择的UIColor。

Answer 2

添加＆＃34; NSStrikethroughColorAttributeName＆＃34;属性为字符串

[attributedString addAttributes:@{NSStrikethroughStyleAttributeName: @(NSUnderlineStyleSingle)
                              , NSStrikethroughColorAttributeName: [UIColor redColor]
                              , NSBackgroundColorAttributeName: [UIColor yellowColor]}

Answer 3

SWIFT 3.x

要删除带有颜色的文本标签，您需要2个属性，一个用于NSStrikethroughStyleAttributeName，一个用于NSStrikethroughColorAttributeName。我发现它更具可读性。

    let attributedString = NSMutableAttributedString(string: "0,91 €")
    attributedString.addAttribute(NSStrikethroughStyleAttributeName, value: NSNumber(value: NSUnderlineStyle.styleSingle.rawValue), range: NSMakeRange(0, attributedString.length))
    attributedString.addAttribute(NSStrikethroughColorAttributeName, value: UIColor.red, range: NSMakeRange(0, attributedString.length))

Answer 4

在Swift中：

attributeString.addAttribute(NSStrikethroughColorAttributeName, value: UIColor.redColor(), range: NSMakeRange(0, attributeString.length))

Answer 5

SWIFT 4.2

@llker Baltaci的Swift 4.2答案更新

let attributedString = NSMutableAttributedString(string: "0,91 €")
attributedString.addAttribute(NSAttributedString.Key.strikethroughStyle, value: NSNumber(value: NSUnderlineStyle.single.rawValue), range: NSMakeRange(0, attributedString.length))
attributedString.addAttribute(NSAttributedString.Key.strikethroughColor, value: UIColor.darkGray, range: NSMakeRange(0, attributedString.length))
