根据选择的日期自动计算天数
1、以12点为节点
+ (CGFloat)beginFKBTime:(NSString *)bTime endFKBTime:(NSString *)eTime{
NSArray *bArray = [bTime componentsSeparatedByString:@" "];
NSArray *eArray = [eTime componentsSeparatedByString:@" "];
NSDateFormatter *Formatter=[[NSDateFormatter alloc] init];
[Formatter setDateFormat:@"yyyy-MM-dd HH:mm"];
[Formatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
NSDate *bDate = [Formatter dateFromString:bTime];
NSDate *eDate = [Formatter dateFromString:eTime];
NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd"];
[dateFormatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
NSDate *bDate5 = [dateFormatter dateFromString:bArray.firstObject];
NSDate *eDate5 = [dateFormatter dateFromString:eArray.firstObject];
NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
unsigned int unitFlags = NSCalendarUnitDay;
NSDateComponents *comps = [gregorian components:unitFlags fromDate:bDate5 toDate:eDate5 options:0];
CGFloat time = 0;
BOOL bTimeAF = NO;//是否上午出发
BOOL eTimeAF = NO;//是否上午回来
NSDate *bDate1 = [bDate earlierDate:[Formatter dateFromString:[NSString stringWithFormat:@"%@ 12:00",bArray.firstObject]]];
NSDate *eDate1 = [eDate earlierDate:[Formatter dateFromString:[NSString stringWithFormat:@"%@ 12:00",eArray.firstObject]]];
if ([comps day] == 0) {
if ([bDate isEqualToDate:bDate1]) {
bTimeAF = YES;
}
if ([eDate isEqualToDate:eDate1]) {
eTimeAF = YES;
}
if (bTimeAF && eTimeAF) {//上午出发 上午回来
time = 0.5;
}else if (bTimeAF && eTimeAF == NO){//上午出发 下午回来
time = 1.0;
}else if (!bTimeAF && !eTimeAF){//下午出发 下午回来
time = 0.5;
}else if (bTimeAF == NO && eTimeAF){//下午出发 上午回来
time = 0;
}
}else{
if ([bDate isEqualToDate:bDate1]) {
bTimeAF = YES;
}
if ([eDate isEqualToDate:eDate1]) {
eTimeAF = YES;
}
if (bTimeAF && eTimeAF) {//上午出发 上午回来
time = 0.5;
}else if (bTimeAF && eTimeAF == NO){//上午出发 下午回来
time = 1.0;
}else if (!bTimeAF && !eTimeAF){//下午出发 下午回来
time = 0.5;
}else if (bTimeAF == NO && eTimeAF){//下午出发 上午回来
time = 0;
}
}
return [comps day] + time;
}
2、正常的计算
+ (NSInteger)startDate:(NSDate *)startDate endDate:(NSDate *)endDate {
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
NSDateComponents * comp = [calendar components:NSCalendarUnitDay
fromDate:startDate
toDate:endDate
options:NSCalendarWrapComponents];
return comp.day;
}
