swift - 在 Swift 3 中设置明天的时间

Question

我需要为明天的某个时间设置一个 Date 对象。我可以弄清楚如何将日期更改为明天，但不知道如何设置时间。这是我的功能:

func getTomorrowAt(hour: Int, minutes: Int) -> Date {
   let calendar = Calendar.current
   var date = calendar.date(byAdding: .day, value: 1, to: Date())

   // here I need to set the time to hour:minutes


   return date!
}

Answer 1

将小时和分钟传递给此函数:

func getTomorrowAt(hour: Int, minutes: Int) -> Date {
let today = Date()
let morrow = Calendar.current.date(byAdding: .day, value: 1, to: today)
return Calendar.current.date(bySettingHour: hour, minute: minutes, second: 0, of: morrow)

}
