Ios 如何使用删除线文本创建UILabel？

我想创建一个

UILabel

，其中的文本如下

myLabel.attributedText = "my string".strikeThrough()

---

我该怎么做？当文本很小时，行也应该很小。

您可以在IOS 6中使用NSMutableAttributedString进行此操作

NSMutableAttributedString *attString=[[NSMutableAttributedString alloc]initWithString:@"$198"];
[attString addAttribute:NSStrikethroughStyleAttributeName value:[NSNumber numberWithInt:2] range:NSMakeRange(0,[attString length])];
yourLabel.attributedText = attString;

---

您可以在IOS 6中使用NSMutableAttributeString来完成此操作

NSMutableAttributedString *attString=[[NSMutableAttributedString alloc]initWithString:@"$198"];
[attString addAttribute:NSStrikethroughStyleAttributeName value:[NSNumber numberWithInt:2] range:NSMakeRange(0,[attString length])];
yourLabel.attributedText = attString;

---

SWIFT 4更新代码

let attributeString: NSMutableAttributedString =  NSMutableAttributedString(string: "Your Text")
    attributeString.addAttribute(NSAttributedString.Key.strikethroughStyle, value: 2, range: NSMakeRange(0, attributeString.length))

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

然后：

使字符串的某些部分敲击，然后提供范围

let somePartStringRange = (yourStringHere as NSString).range(of: "Text")
attributeString.addAttribute(NSStrikethroughStyleAttributeName, value: 2, range: somePartStringRange)

NSString* strPrice = @"£399.95";

NSMutableAttributedString *titleString = [[NSMutableAttributedString alloc] initWithString:strPrice];

[finalString addAttribute: NSStrikethroughStyleAttributeName value:[NSNumber numberWithInteger: NSUnderlineStyleSingle] range: NSMakeRange(0, [titleString length])];
self.lblOldPrice.attributedText = finalString;   

let example = NSAttributedString(string: "440").withStrikeThrough(1)
myLabel.attributedText = example

---

目标-C

在iOS 6.0中

UILabel

支持

nsattributestring

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

Swift

let attributeString: NSMutableAttributedString =  NSMutableAttributedString(string: "Your String here")
attributeString.addAttribute(NSStrikethroughStyleAttributeName, value: 2, range: NSMakeRange(0, attributeString.length))

定义：

- (void)addAttribute:(NSString *)name value:(id)value range:(NSRange)aRange

参数列表：

名称：指定属性名称的字符串。属性键可以由另一个框架提供，也可以是您定义的自定义键。有关在何处查找系统提供的属性键的信息，请参阅NSAttributedString类参考中的概述部分

值：与名称关联的属性值

aRange：指定属性/值对应用的字符范围

然后

对于低于iOS 6.0版本的

，您需要
第三方组件来执行此操作。

对于这个简单的例子，我更喜欢
NSAttributedString
而不是
NSMutableAttributedString
：

NSAttributedString * title =
    [[NSAttributedString alloc] initWithString:@"$198"
                                    attributes:@{NSStrikethroughStyleAttributeName:@(NSUnderlineStyleSingle)}];
[label setAttributedText:title];


用于指定属性字符串的
NSUnderlineStyleAttributeName
和
nsStrikethrowStyleAttributeName
属性的常量：

typedef enum : NSInteger {  
  NSUnderlineStyleNone = 0x00,  
  NSUnderlineStyleSingle = 0x01,  
  NSUnderlineStyleThick = 0x02,  
  NSUnderlineStyleDouble = 0x09,  
  NSUnderlinePatternSolid = 0x0000,  
  NSUnderlinePatternDot = 0x0100,  
  NSUnderlinePatternDash = 0x0200,  
  NSUnderlinePatternDashDot = 0x0300,  
  NSUnderlinePatternDashDotDot = 0x0400,  
  NSUnderlineByWord = 0x8000  
} NSUnderlineStyle;  

对于这种简单的情况，我更喜欢

NSAttributedString * title =
    [[NSAttributedString alloc] initWithString:@"$198"
                                    attributes:@{NSStrikethroughStyleAttributeName:@(NSUnderlineStyleSingle)}];
[label setAttributedText:title];

 使用下面的代码

let somePartStringRange = (yourStringHere as NSString).range(of: "Text")
attributeString.addAttribute(NSStrikethroughStyleAttributeName, value: 2, range: somePartStringRange)

NSString* strPrice = @"£399.95";

NSMutableAttributedString *titleString = [[NSMutableAttributedString alloc] initWithString:strPrice];

myLabel.attributedText = example

使用下面的代码

let somePartStringRange = (yourStringHere as NSString).range(of: "Text")
attributeString.addAttribute(NSStrikethroughStyleAttributeName, value: 2, range: somePartStringRange)

NSString* strPrice = @"£399.95";

NSMutableAttributedString *titleString = [[NSMutableAttributedString alloc] initWithString:strPrice];

[finalString addAttribute: NSStrikethroughStyleAttributeName value:[NSNumber numberWithInteger: NSUnderlineStyleSingle] range: NSMakeRange(0, [titleString length])];
self.lblOldPrice.attributedText = finalString;   

let example = NSAttributedString(string: "440").withStrikeThrough(1)
myLabel.attributedText = example

在Swift中，对单删除线样式使用枚举：

let attrString = NSAttributedString(string: "Label Text", attributes: [NSStrikethroughStyleAttributeName: NSUnderlineStyle.StyleSingle.rawValue])
label.attributedText = attrString

其他删除线样式（记住使用.rawValue访问枚举）：


NSUnderlineStyle.StyleNone
NSUnderlineStyle.StyleSingle
NSUnderlineStyle.StyleThick
NSUnderlineStyle.StyleDouble

删除线图案（与样式一起或一起使用）：


NSUnderlineStyle.PatternDot
NSUnderlineStyle.PatternDash
NSUnderlineStyle.PatternDashDot
NSUnderlineStyle.PatternDashDotDot

指定删除线仅应用于单词（而不是空格）：


NSUnderlineStyle.ByWord
在Swift中，将枚举用于单删除线样式：

let attrString = NSAttributedString(string: "Label Text", attributes: [NSStrikethroughStyleAttributeName: NSUnderlineStyle.StyleSingle.rawValue])
label.attributedText = attrString

其他删除线样式（记住使用.rawValue访问枚举）：


NSUnderlineStyle.StyleNone
NSUnderlineStyle.StyleSingle
NSUnderlineStyle.StyleThick
NSUnderlineStyle.StyleDouble

删除线图案（与样式一起或一起使用）：


NSUnderlineStyle.PatternDot
NSUnderlineStyle.PatternDash
NSUnderlineStyle.PatternDashDot
NSUnderlineStyle.PatternDashDotDot

指定删除线仅应用于单词（而不是空格）：


NSUnderlineStyle.ByWord
对于任何正在查看如何在tableview单元格（Swift）中执行此操作的人，您必须如下设置.attributeText：

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("TheCell")!

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

    cell.textLabel?.attributedText =  attributeString

    return cell
    }

如果要删除删除删除线，请执行此操作，否则它将粘住！：

cell.textLabel?.attributedText =  nil

对于那些面临多行文字罢工问题的人

    let attributedString = NSMutableAttributedString(string: item.name!)
    //necessary if UILabel text is multilines
    attributedString.addAttribute(NSBaselineOffsetAttributeName, value: 0, range: NSMakeRange(0, attributedString.length))
     attributedString.addAttribute(NSStrikethroughStyleAttributeName, value: NSNumber(value: NSUnderlineStyle.styleSingle.rawValue), range: NSMakeRange(0, attributedString.length))
    attributedString.addAttribute(NSStrikethroughColorAttributeName, value: UIColor.darkGray, range: NSMakeRange(0, attributedString.length))

    cell.lblName.attributedText = attributedString

     attributedString.addAttribute(NSStrikethroughStyleAttributeName, value: NSNumber(value: NSUnderlineStyle.styleSingle.rawValue), range: NSMakeRange(0, attributedString.length))
    attributedString.addAttribute(NSStrikethroughColorAttributeName, value: UIColor.darkGray, range: NSMakeRange(0, attributedString.length))

    cell.lblName.attributedText = attributedString

SWIFT 4

    let attributeString: NSMutableAttributedString =  NSMutableAttributedString(string: "Your Text Goes Here")
    attributeString.addAttribute(NSAttributedStringKey.strikethroughStyle, value: NSUnderlineStyle.styleSingle.rawValue, range: NSMakeRange(0, attributeString.length))
    self.lbl_productPrice.attributedText = attributeString

另一种方法是使用字符串扩展名

扩展

extension String{
    func strikeThrough()->NSAttributedString{
        let attributeString: NSMutableAttributedString =  NSMutableAttributedString(string: self)
        attributeString.addAttribute(NSAttributedStringKey.strikethroughStyle, value: NSUnderlineStyle.styleSingle.rawValue, range: NSMakeRange(0, attributeString.length))
        return attributeString
    }
}

调用函数：像这样使用它

testUILabel.attributedText = "Your Text Goes Here!".strikeThrough()

删除Swift iOS中的UILabel文本。请试试这个它对我有用

let attributedString = NSMutableAttributedString(string:"12345")
                      attributedString.addAttribute(NSAttributedStringKey.baselineOffset, value: 0, range: NSMakeRange(0, attributedString.length))
