如何获取当前时间作为日期时间

Swift 3更新：

let date = Date()let calendar = Calendar.currentlet hour = calendar.component(.hour, from: date)let minutes = calendar.component(.minute, from: date)

我这样做：

let date = NSDate()let calendar = NSCalendar.currentCalendar()let components = calendar.components(.CalendarUnitHour | .CalendarUnitMinute, fromDate: date)let hour = components.hourlet minutes = components.minute

在Objective-c中看到相同的问题，如何从NSDate获得小时和分钟？与Nate的答案相比，您将获得一个数字，而不是字符串……选择您的选择！
