Question

我有阵列;

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

我有3个变量，startDate，endDate，dates，我想追加变量，比如;

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

将日期变量添加到 =＆＃34; 2018-03-01,2018-03-02,2018-03-03＆＃34;在开始和结束日期之间的所有日期之间。

我怎么能在swift 2中做到这一点？

Answer 1

这里是打印两个日期之间的所有日期的解决方案（快速4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

输出为：

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

Swift 2 for循环低和高日期之间
