iOS 时间戳操作

我们在开发中会遇到各种对于时间戳的操作，这里分享下比较常用的几种。

1.当前时间戳

1 NSString *timeSp = [NSString stringWithFormat:@"%ld", (long)[[NSDate date]timeIntervalSince1970]];
2 NSLog(@"现在时间戳%@",timeSp);

2.今天凌晨时间戳  （直接复制粘贴该方法即可，返回值即为今天凌晨时间戳）

 1 #pragma mark 今天凌晨时间戳
 2
 3 -(NSString*)getLingChenTimeStamp
 4  {
 5 　　NSInteger year,month,day,hour,min,sec,week;
 6
 7 　　NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
 8
 9 　　NSDate *now = [NSDate date];;
10
11 　　NSDateComponents *comps = [[NSDateComponents alloc] init];
12
13 　　NSInteger unitFlags = NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay |     NSCalendarUnitWeekday | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond;
14
15 　　comps = [calendar components:unitFlags fromDate:now];
16
17 　　year = [comps year];
18
19 　　week = [comps weekday];
20
21 　　month = [comps month];
22
23 　　day = [comps day];
24
25 　　hour = [comps hour];
26
27 　　min = [comps minute];
28
29 　　sec = [comps second];
30
31 　　NSString * dateString = @"";
32
33 　　dateString = [NSString stringWithFormat:@"%ld-%ld-%ld 00:00:00",(long)year,(long)month,(long)day];//修改此处的 00:00:00 可以得到想要的时间 例如 12:00:00

34 35 　　NSDateFormatter * dateFormat = [[NSDateFormatter alloc]init]; 36 37 　　[dateFormat setDateFormat:@"yyyy-MM-dd hh:mm:ss"]; 38 　　NSDate * date = [dateFormat dateFromString:dateString]; 39 40 　　NSString * today = [NSString stringWithFormat:@"%ld",(long)[datetimeIntervalSince1970]]; 41 42 　　NSLog(@"今天凌晨时间戳：%@",today); 43 　　return today; 44 }

3.周日凌晨时间戳 （直接复制粘贴该方法即可，返回值可以是 本周周日凌晨 上周周日凌晨 下周周日凌晨时间戳）

 1 -(NSString*)getSundayTime
 2 {
 3     NSIntegeryear,month,day,hour,min,sec,week;
 4
 5     NSCalendar *calendar =     [[NSCalendaralloc]initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
 6
 7     NSDate*now = [NSDate date];;
 8
 9     NSDateComponents *comps = [[NSDateComponents alloc] init];
10
11     NSInteger unitFlags = NSCalendarUnitYear |NSCalendarUnitMonth     |NSCalendarUnitDay|NSCalendarUnitWeekday | NSCalendarUnitHour |NSCalendarUnitMinute |NSCalendarUnitSecond;
12
13     comps = [calendar components:unitFlags fromDate:now];
14
15     year = [comps year];
16
17     week = [comps weekday];
18
19     month = [comps month];
20
21     day = [comps day];
22
23     hour = [comps hour];
24
25     min = [comps minute];
26
27     sec = [comps second];
28
29     NSString * todayDateString = @"";
30
31     todayDateString = [NSString stringWithFormat:@"%ld-%ld-%ld 00:00:00",(long)year,(long)month,(long)day];//修改这里00：00：00可以得到想要的时间 例如 12:00:00
32
33
34     NSDateFormatter * todayDateFormat = [[NSDateFormatter alloc]init];
35
36     [todayDateFormat setDateFormat:@"yyyy-MM-dd hh:mm:ss"];
37
38     NSDate * todayDate = [todayDateFormat dateFromString:todayDateString];
39
40     NSDate* thisweek = [NSDate dateWithTimeIntervalSince1970:([todayDate timeIntervalSince1970] +(8 - week) * 24*60*60)];
41
42     NSString * thisWeekStmp = [NSString stringWithFormat:@"%ld",(long)[thisweektimeIntervalSince1970]];//本周日凌晨时间戳
43
44     NSString * lastlastWeekStmp = [NSString stringWithFormat:@"%ld",(long)[thisweektimeIntervalSince1970]-3600*24*7*2];//上上周日凌晨时间戳
45
46     NSString * lastWeekStmp = [NSString stringWithFormat:@"%ld",(long)[thisweektimeIntervalSince1970]-3600*24*7];//上周日凌晨时间戳
47
48     NSString * nextWeekStmp = [NSString stringWithFormat:@"%ld",(long)[thisweektimeIntervalSince1970]+3600*24*7];//下周日凌晨时间戳
49
50     NSString * nextnextWeekStmp = [NSString stringWithFormat:@"%ld",(long)[thisweektimeIntervalSince1970]+3600*24*7*2];//下周日凌晨时间戳
51
52     NSLog(@"本周周日凌晨时间戳%@",thisWeekStmp);
53
54     NSLog(@"上周周日凌晨时间戳%@",lastWeekStmp);
55
56     NSLog(@"上上周周日凌晨时间戳%@",lastlastWeekStmp);
57
58     NSLog(@"下周日凌晨时间戳%@",nextWeekStmp);
59
60     NSLog(@"下下周日凌晨时间戳%@",nextnextWeekStmp);
61
62     return thisWeekStmp;
63 }
