如何在两个日期之间快速获取30分钟时隙数组
如何在两个日期之间快速获取30分钟时隙数组
提问于 2018-05-29 09:02:14
例如：
startDate:- 20-08-2018 10:00 AM
endDate:- 20-08-2018 02:30 PM输出：“上午10:00”、“上午10:30”、"11:00“、"11:30”、“12:00”、"12:30“、"01:00”、"01:30“、"02:00 PM”、"02:30 PM“
var fromTime:Date = getFromTime
fromTime = fromTime.addingTimeInterval(-1800)
guard let toTime:Date = timeFormat.date(from:endTime) else {
return nil
}
var dateByAddingThirtyMinute : Date!
let timeinterval : TimeInterval = toTime.timeIntervalSince(fromTime)
let numberOfIntervals : Double = timeinterval / 3600;
var timeArrayAM = [String]()
var timeArrayPM = [String]()
for _ in stride(from: 0, to: Int(numberOfIntervals * 2), by: 1) {
dateByAddingThirtyMinute = fromTime.addingTimeInterval(1800)
fromTime = dateByAddingThirtyMinute
if let dateString = dateByAddingThirtyMinute.format(with: "hh:mm a") as? String {
// print("Time after 30 min = \(dateString)")
if temp == 0 {
let time = dateString
guard let getStopTime = timeFormat.date(from: time) else {
return nil
}
var stopTime = getStopTime
var date = Date()
date = date.addingTimeInterval(TimeInterval(advanceTimeInterval*60))
let calendar = Calendar.current
let year = calendar.component(.year, from: date)
let month = calendar.component(.month, from: date)
let day = calendar.component(.day, from: date)
let hour = calendar.component(.hour, from: stopTime)
let minute = calendar.component(.minute, from: stopTime)
stopTime = calendar.date(bySetting: .year, value: year, of: stopTime)!
stopTime = calendar.date(bySetting: .month, value: month, of: stopTime)!
stopTime = calendar.date(bySetting: .day, value: day, of: stopTime)!
stopTime = calendar.date(bySetting: .hour, value: hour, of: stopTime)!
stopTime = calendar.date(bySetting: .minute, value: minute, of: stopTime)!
let timeDifference = calendar.dateComponents([.hour, .minute], from: stopTime, to: date)
// print_debug("************************************")
// print(timeDifference.hour, timeDifference.minute)
if timeDifference.hour! < 0 || timeDifference.minute! < 0 || (timeDifference.hour! == 0 && timeDifference.minute! == 0 ) {
showFirstTime = dateString
temp = 1
}
// print_debug("************************************")

你能做到的
var array: [String] = []
let formatter = DateFormatter()
formatter.dateFormat = "dd-MM-yyyy hh:mm a"
let formatter2 = DateFormatter()
formatter2.dateFormat = "hh:mm a"
let startDate = "20-08-2018 10:00 AM"
let endDate = "20-08-2018 02:30 PM"
let date1 = formatter.date(from: startDate)
let date2 = formatter.date(from: endDate)
var i = 1
while true {
let date = date1?.addingTimeInterval(TimeInterval(i*30*60))
let string = formatter2.string(from: date!)
if date! >= date2! {
break;
}
i += 1
array.append(string)
}
print(array)上面的输出是，
["10:30 AM", "11:00 AM", "11:30 AM", "12:00 PM", "12:30 PM", "01:00 PM", "01:30 PM", "02:00 PM", "02:30 PM"]Stack Overflow用户

在两次约会之间有30分钟的时间。
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
setTimeArray()
}
func setTimeArray(){
var array: [String] = []
let formatter = DateFormatter()
formatter.dateFormat = "dd-MM-yyyy HH:mm"
let formatter2 = DateFormatter()
formatter2.dateFormat = "hh:mm a"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd-MM-yyyy"
let dt = Date()
let nxtDt = dt.getNextDate()
let Curdate = dt.DateToString(Formatter: "dd-MM-yyyy")
let Nxtdate = nxtDt.DateToString(Formatter: "dd-MM-yyyy")
let startDate = "\(Curdate) 10:00"
let endDate = "\(Nxtdate) 00:00"
let date1 = formatter.date(from: startDate)
let date2 = formatter.date(from: endDate)
let interval = 30
let string = formatter2.string(from: date1!)
array.append(string)
var i = 1
while true {
let date = date1?.addingTimeInterval(TimeInterval(i*interval!*60))
let string = formatter2.string(from: date!)
if date! >= date2! {
break;
}
i += 1
array.append(string)
}
}输出是：
["10:00 AM", "10:30 AM", "11:00 AM", "11:30 AM", "12:00 PM", "12:30 PM", "01:00 PM", "01:30 PM", "02:00 PM", "02:30 PM", "03:00 PM", "03:30 PM", "04:00 PM", "04:30 PM", "05:00 PM", "05:30 PM", "06:00 PM", "06:30 PM", "07:00 PM", "07:30 PM", "08:00 PM", "08:30 PM", "09:00 PM", "09:30 PM", "10:00 PM", "10:30 PM", "11:00 PM", "11:30 PM"]页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
