Answer 1

试试这个

NSDictionary *attrs = @{ NSFontAttributeName:[UIFont systemFontOfSize:12.0f],
                         NSStrikethroughStyleAttributeName: @(NSUnderlineStyleSingle),
                         NSStrikethroughColorAttributeName: [UIColor redColor],
                         NSBackgroundColorAttributeName: [UIColor yellowColor]
                       };

NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:@"Old price"];
NSRange range = NSMakeRange(0, [str length]);
[str addAttribute:NSStrikethroughStyleAttributeName value:@2 range:range];
[str addAttribute:NSStrikethroughColorAttributeName value:[UIColor greenColor] range:range];
[str addAttribute:NSForegroundColorAttributeName value:[UIColor greenColor] range:range];
