iOS 设置NSMutableAttributedString删

// 遇到设置删除线不能显示的时候,多添加个属性(NSBaselineOffsetAttributeName)

[titleString addAttributes:@{NSStrikethroughStyleAttributeName : @(NSUnderlineStyleSingle),NSStrikethroughColorAttributeName : ThemeColor,NSBaselineOffsetAttributeName : @(0)} range:NSMakeRange(0, titleString.length)];
