代码中提到了sonar bug在多个类中如何处理这个

if ([orderTypeS isEqualToString:kOrderDelivery]) {
            [dateSetFormat setDateFormat:@"MM/dd/yy hh:mm a"];
            checkHolidayDate  = [dateSetFormat dateFromString:checkHolidyString];
            if (!checkHolidayDate) {
                [dateSetFormat setDateFormat:@"MM/dd/yy"];
                checkHolidayDate  = [dateSetFormat dateFromString:dateStr];
            }else{
                
            }
        }else{
            [dateSetFormat setDateFormat:@"MM/dd/yy hh:mm a"];
            checkHolidayDate  = [dateSetFormat dateFromString:checkHolidyString];
            if(!checkHolidayDate){
                checkHolidayDate  = [dateSetFormat dateFromString:checkHolidyString];
            }else{
               
            }
