NSStrikethroughStyleAttributeName(删除线)

NSStrikethroughStyleAttributeName 设置删除线，取值为 NSNumber 对象（整数），枚举常量 NSUnderlineStyle中的值：

    NSUnderlineStyleNone 不设置删除线
    NSUnderlineStyleSingle 设置删除线为细单实线
    NSUnderlineStyleThick 设置删除线为粗单实线
    NSUnderlineStyleDouble 设置删除线为细双实线

默认值是NSUnderlineStyleNone。

• NSRange range = [@"123456" rangeOfString:@"456"];
