Swift 2 for 循环低和高日期之间

Question

我有数组；

var mydates             : [String] = []
let startDate           = "2018-03-01"
let endDate             = "2018-03-03"

我有 3 个变量，startDate，endDate，dates，我想附加这些变量，比如；

如果startDate = 2018-03-01，并且endDate = 2018-03-03

将在开始日期和结束日期的所有日期之间添加 dates variable inside = "2018-03-01,2018-03-02,2018-03-03"。

我怎样才能在 swift 2 中做到这一点？

Answer 1

这是打印两个日期之间的所有日期的解决方案（Swift 4 代码）

var mydates : [String] = []
let startDate = "2018-03-01"
let endDate   = "2018-03-05"

var dateFrom =  Date() // First date
var dateTo = Date()   // Last date

// Formatter for printing the date, adjust it according to your needs:
let fmt = DateFormatter()
fmt.dateFormat = "yyy-MM-dd"
dateFrom = fmt.date(from: startDate)!
dateTo = fmt.date(from: endDate)!


while dateFrom <= dateTo {
    mydates.append(fmt.string(from: dateFrom))
    dateFrom = Calendar.current.date(byAdding: .day, value: 1, to: dateFrom)!

}

print(mydates) // Your Result

输出是：

["2018-03-01", "2018-03-02", "2018-03-03", "2018-03-04", "2018-03-05"]
