21 // let hours = Int(interval/(60*60))
22 // let mins = Int(interval/60)
23 return days
24 }
最后就是方法的调用与后台的输出
1 let date = Date()
2 print(date.getDateString())
3 print(date.getDateWeekday())
4 print(date.getTimeStamp())
6 let dateA = Utility.getDateFromTimestamp(1507605071)
7 let dateB = Utility.getDateFromTimestamp(1507877163)
8 let days = Utility.getDateInterval(dateA: dateA, dateB: dateB)
9 print(days)
