主要排序代码如下：
使用冒泡算法进行对日期和时间的排序，在AttenceTimelineCell基础上添加分段：
#pragma mark-对日期进行分类- (NSMutableArray *)siftArray:(NSMutableArray *)mArray{    NSMutableArray *resultArray = [NSMutableArray array];    for (int i = 0; i < mArray.count; i++) {        DataModel *iModel = mArray[i];        NSString *modelDate = [iModel.expense_time substringToIndex:10];        // 加入数组        NSMutableArray *tempArray = [NSMutableArray array];        [tempArray addObject:iModel];        for (int j = i + 1; j < mArray.count; j++) {            DataModel *jModel = mArray[j];            NSString *jModelDate = [jModel.expense_time substringToIndex:10];            if ([modelDate isEqualToString:jModelDate]) {                [tempArray addObject:jModel];            }        }        if (tempArray.count > 0) {            //对日期进行排序，从最近到最远            tempArray=[self sortDateWithArray:tempArray sortType:ZWSortType_Asc];            [resultArray addObject:tempArray];            resultArray = [self sortDayWithArray:resultArray sortType:ZWSortType_Asc];            [mArray removeObjectsInArray:tempArray];            i--;        }    }    return resultArray;}#pragma Mark-对日期进行排序-(NSMutableArray *)sortDayWithArray:(NSMutableArray *)msArray sortType:(ZWSortType)type{    switch (type) {            //降序        case ZWSortType_Asc:        {            for (int i = 0; i < msArray.count; i++) {                DataModel *date1 = msArray[i][0];                for (int j = i + 1; j < msArray.count; j++) {                     DataModel *date2 = msArray[j][0];                    if ([self compareDate:date1.expense_time withModelDate:date2.expense_time]) {                        [msArray exchangeObjectAtIndex:j withObjectAtIndex:i];                    }                }            }        }            //升序        case ZWSortType_Order:        {            for (int i = 0; i < msArray.count; i++) {                DataModel *date1 = msArray[i][0];                for (int j = i + 1; j < msArray.count; j++) {                    DataModel *date2 = msArray[j][0];                    if (![self compareDate:date1.expense_time withModelDate:date2.expense_time]) {                        [msArray exchangeObjectAtIndex:j withObjectAtIndex:i];                    }                }            }        }        break;        default:        break;    }    return msArray;}#pragma mark -对时间进行排序-(NSMutableArray *)sortDateWithArray:(NSMutableArray *)msArray sortType:(ZWSortType)type{    switch (type) {        //降序        case ZWSortType_Asc:        {            for (int i = 0; i < msArray.count; i++) {                DataModel *model1 = msArray[i];                for (int j = i + 1; j < msArray.count; j++) {                    DataModel *model2 = msArray[j];                    if ([self compareDate:model1.expense_time withModelDate:model2.expense_time]) {                        [msArray exchangeObjectAtIndex:j withObjectAtIndex:i];                    }                }            }        }        break;        //升序        case ZWSortType_Order:        {            for (int i = 0; i < msArray.count; i++) {                DataModel *model1 = msArray[i];                for (int j = i + 1; j < msArray.count; j++) {                    DataModel *model2 = msArray[j];                    if (![self compareDate:model1.expense_time withModelDate:model2.expense_time]) {                        [msArray exchangeObjectAtIndex:j withObjectAtIndex:i];                    }                }            }        }        break;        default:            break;    }    return msArray;}
效果如下：
