之前开发也遇到过酒店，火车票日历，我用了一款第三方软件，前期还行，随着后期功能（业务）增多，就不好使了，特别是那个循环架构，年 月 日这种的，修改起来特别麻烦。
新增业务例如：
1、价格日历，景点价格日历，机票价格日历
2、基地日历，我们基地价格分批次的 1-8天 110元/天，9-20天100 ，21-30天90，这就要求选择开始日期后，重新刷新数据，只能选择天数区域内的时间。
3、活动日历，活动不是每天搞，隔三差五的，一句话就是可点不可点，传日期输入，处理后展示出来。

typedef NS_ENUM(NSInteger, MSSCalendarViewControllerType)
{
MSSCalendarViewControllerLastType = 0,// 只显示当前月之前
MSSCalendarViewControllerMiddleType,// 前后各显示一半
MSSCalendarViewControllerNextType// 只显示当前月之后
};
typedef NS_ENUM(NSInteger, MSSCalendarWithUserType)
{
MSSCalendarHotelType = 0, // 酒店 入住 --- 离店
MSSCalendarTrainType, // 火车票，飞机票，单选无价格
MSSCalendarAplaceType, // 基地 价格
MSSCalendarSecnicType, // 景点 价格

};
可以自定义以上属性，什么颜色，类型什么的。
核心思路就在这块，简单明了，传的有一个参数limitMonth，显示几个月的数据，MSSCalendarViewControllerNextType就是今天以后， components.month -= 1;获取当前月份减一，不要问为什么减一，打隔断点看看就知道了，MSSCalendarViewControllerLastType这是今天以前的limitMonth月的日期。
- (NSArray *)getCalendarDataSoruceWithLimitMonth:(NSInteger)limitMonth type:(MSSCalendarViewControllerType)type
{
NSMutableArray *resultArray = [[NSMutableArray alloc]init];
NSDateComponents *components = [self dateToComponents:_todayDate];
components.day = 1;
if(type == MSSCalendarViewControllerNextType)
{
components.month -= 1;
}
else if(type == MSSCalendarViewControllerLastType)
{
components.month -= limitMonth;
}
else
{
components.month -= (limitMonth + 1) / 2;
}
NSInteger i = 0;
for(i = 0;i < limitMonth;i++)
{
components.month++;
MSSCalendarHeaderModel *headerItem = [[MSSCalendarHeaderModel alloc]init];
NSDate *date = [self componentsToDate:components];
[_dateFormatter setDateFormat: @"yyyy年MM月"];
NSString *dateString = [_dateFormatter stringFromDate:date];
headerItem.headerText = dateString;
headerItem.calendarItemArray = [self getCalendarItemArrayWithDate:date section:i]; // section就是当月数据页面的位置
[resultArray addObject:headerItem];
}
return resultArray;
}
一共limitMonth个月，从第一个月开始排序，整理数组。下面是每一个单独月的日期数据
// 得到每一天的数据源
- (NSArray *)getCalendarItemArrayWithDate:(NSDate *)date section:(NSInteger)section
{
NSMutableArray *resultArray = [[NSMutableArray alloc]init];
NSInteger tatalDay = [self numberOfDaysInCurrentMonth:date]; // 本月多少天
NSInteger firstDay = [self startDayOfWeek:date]; // 本月第一天是周几
// 0 星期日 1 星期一 6星期六
NSDateComponents *components = [self dateToComponents:date];
// 判断日历有多少列
// 一共多少天 加 第一天是周几就可以算出本月cell的数量
NSInteger tempDay = tatalDay + (firstDay - 1);
NSInteger column = 0;
if(tempDay % 7 == 0)
{
column = tempDay / 7;
}else{
column = tempDay / 7 + 1;
}
NSInteger i = 0;
NSInteger j = 0;
components.day = 0;
for(i = 0;i < column;i++)
{
for(j = 0;j < 7;j++)
{
if(i == 0 && j < firstDay - 1) // 本月第一天前的数据
{
MSSCalendarModel *calendarItem = [[MSSCalendarModel alloc]init];
calendarItem.year = 0;
calendarItem.month = 0;
calendarItem.day = 0;
calendarItem.chineseCalendar = @"";
calendarItem.holiday = @"";
calendarItem.week = -1;
calendarItem.dateInterval = -1;
[resultArray addObject:calendarItem];
continue;
}
components.day += 1;
if(components.day == tatalDay + 1) // 本月数据循环结束
{
i = column;// 结束外层循环
break;
}
MSSCalendarModel *calendarItem = [[MSSCalendarModel alloc]init];
calendarItem.year = components.year;
calendarItem.month = components.month;
calendarItem.day = components.day;
calendarItem.week = j;
NSDate *date = [self componentsToDate:components];
// 时间戳
calendarItem.dateInterval = [self dateToInterval:date];
if(_startDate == calendarItem.dateInterval)
{
_startIndexPath = [NSIndexPath indexPathForRow:0 inSection:section];
}
[self setChineseCalendarAndHolidayWithDate:components date:date calendarItem:calendarItem];
[resultArray addObject:calendarItem];
}
}
return resultArray;
}
价格日历这块，无非就是处理数据的时候加上了priceArray
@[ @{@"date":@"2018-09-08",@"price":@"238"}]
- (NSArray *)getJYCCalendarDataSoruceWithLimitMonth:(NSInteger)limitMonth type:(MSSCalendarViewControllerType)type calendarType:(MSSCalendarWithUserType)calendarType priceArray:(NSArray *_Nonnull)priceArray{
NSMutableArray *resultArray = [[NSMutableArray alloc]init];
NSMutableArray *priceMuArr = [NSMutableArray arrayWithArray:priceArray];
NSDateComponents *components = [self dateToComponents:_todayDate];
components.day = 1;
if(type == MSSCalendarViewControllerNextType)
{
components.month -= 1;
}
else if(type == MSSCalendarViewControllerLastType)
{
components.month -= limitMonth;
}
else
{
components.month -= (limitMonth + 1) / 2;
}
NSInteger i = 0;
for(i = 0;i < limitMonth;i++)
{
components.month++;
MSSCalendarHeaderModel *headerItem = [[MSSCalendarHeaderModel alloc]init];
NSDate *date = [self componentsToDate:components];
[_dateFormatter setDateFormat: @"yyyy年MM月"];
NSString *dateString = [_dateFormatter stringFromDate:date];
headerItem.headerText = dateString;
// 价格
NSString *MMyue = [dateString substringWithRange:NSMakeRange(5, 2)];
NSMutableArray *priArr = [NSMutableArray array];
for (NSDictionary *dic in priceMuArr) { // 从数据中选中当月的数据
NSString *da = [dic objectForKey:@"date"];
if (da.length > 7) {
NSString *mm = [da substringWithRange:NSMakeRange(5, 2)];
if (MMyue == mm) {
[priArr addObject:dic];
}
}
}
[priceMuArr removeObjectsInArray:priArr]; // 移除选中月份的数据
headerItem.calendarItemArray = [self getCalendarItemArrayWithDate:date section:i calendarType:calendarType withPriceArray:priArr];
[resultArray addObject:headerItem];
if (calendarType == MSSCalendarSecnicType || calendarType == MSSCalendarAplaceType || calendarType == MSSCalendarActivityType) {
if (priceMuArr.count <= 0) { // 如果价格数据数组为空时，不在展示以后的日历
break;
}
}
}
return resultArray;
}
找到第一天数据的具体时间，然后依次把数组中的数据赋值给第一天后的每一天（必须保证时间日历的连续性）
NSInteger priceTime = 0;
if (priceArray.count > 0) {
NSDictionary *dic = priceArray[0];
NSString *ti = [dic objectForKey:@"date"];
if (ti.length > 0) {
priceTime = [self dateToInterval:[self dateFromString:ti]];
}
}
// 时间戳
NSInteger dateInterVal = [self dateToInterval:date];
calendarItem.dateInterval = dateInterVal;
if (priceTime == dateInterVal) {
indexB = 0;
}
if (indexB < priceArray.count) {
NSDictionary *dic = priceArray[indexB];
// if (calendarType == MSSCalendarSecnicType) {
// calendarItem.price = [dic objectForKey:@"salePrice"];
// }else if (calendarType == MSSCalendarAplaceType){
// calendarItem.userPrice = [dic objectForKey:@"userprice"];
// calendarItem.price = [dic objectForKey:@"webprice"];
// }
calendarItem.price = [dic objectForKey:@"price"];
calendarItem.userInteractionEnabled = YES;
}
indexB++;
基地日历：选择一个开始时间后，后台刷新日历数据，把最小时间以前和最大时间以后的数据全部设置为不可选 userInteractionEnabled = NO;
- (NSArray *)getCalendarDataSoruceWithMinNum:(NSInteger )minNum MaxNum:(NSInteger )maxNum startDate:(NSInteger )startDate endDate:(NSInteger )endDate andDataArray:(NSArray *)dataArray{
NSMutableArray *daArr = [NSMutableArray array];
[daArr addObjectsFromArray:dataArray];
if (startDate > 0) {
for (int i = 0; i < dataArray.count; i++) {
MSSCalendarHeaderModel *headerItem = daArr[i];
for (int j = 0; j < headerItem.calendarItemArray.count; j++) {
MSSCalendarModel *model = headerItem.calendarItemArray[j];
if (model.dateInterval == startDate) {
}
if(model.dateInterval >= startDate + minNum*24*3600 && model.dateInterval <= startDate + maxNum*24*3600){
model.middleSelect = YES;
model.userInteractionEnabled = YES;
}else{
model.userInteractionEnabled = NO;
}
}
}
}
if (endDate > 0 || startDate == 0) {
for (int i = 0; i < dataArray.count; i++) {
MSSCalendarHeaderModel *headerItem = daArr[i];
for (int j = 0; j < headerItem.calendarItemArray.count; j++) {
MSSCalendarModel *model = headerItem.calendarItemArray[j];
if ([model.price floatValue] > 0) {
model.userInteractionEnabled = YES;
model.middleSelect = NO;
}
}
}
}
return daArr;
}

代码参考了一位大神，自己也封装了业务需求。
