Ios 如何创建带有删除线文本的 UILabel

SWIFT 5 UPDATE CODE个

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

然后:

yourLabel.attributedText = attributeString

To make some part of string to strike then provide range

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

Objective-C个

在iOS 6.0 >中UILabel支承座NSAttributedString

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

Swift个

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

Definition:

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

Parameters List:个

name: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.

value: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

yourLabel.attributedText = attributeString;

对于lesser than iOS 6.0 versions，你需要3-rd party component才能做到这一点. 其中一个是TTTAttributedLabel，另一个是OHAttributedLabel.
