问题描述
请考虑我们具有以下函数签名:
Consider that we have a function signature as:
func datesRange(from: Date, to: Date) -> [Date]应从开始使用和至日期实例,并返回一个数组,其中包含其参数之间的日期(天)。
which should take from date and to date instances and returns an array containing the dates (days) between its parameters. How to achieve it?
推荐答案您可以这样实现:
func datesRange(from: Date, to: Date) -> [Date] { // in case of the "from" date is more than "to" date, // it should returns an empty array: if from > to { return [Date]() } var tempDate = from var array = [tempDate] while tempDate < to { tempDate = Calendar.current.date(byAdding: .day, value: 1, to: tempDate)! array.append(tempDate) } return array }用法:
let today = Date() let nextFiveDays = Calendar.current.date(byAdding: .day, value: 5, to: today)! let myRange = datesRange(from: today, to: nextFiveDays) print(myRange) /* [2018-03-20 14:46:03 +0000, 2018-03-21 14:46:03 +0000, 2018-03-22 14:46:03 +0000, 2018-03-23 14:46:03 +0000, 2018-03-24 14:46:03 +0000, 2018-03-25 14:46:03 +0000] */更多推荐
