推荐答案

在 Swift 3.0 中，Apple 移除了NS"前缀，让一切变得简单.以下是从日期"类(NSDate 替代)中获取小时、分钟和秒的方法

In Swift 3.0 Apple removed 'NS' prefix and made everything simple. Below is the way to get hour, minute and second from 'Date' class (NSDate alternate)

let date = Date()
let calendar = Calendar.current

let hour = calendar.component(.hour, from: date)
let minutes = calendar.component(.minute, from: date)
let seconds = calendar.component(.second, from: date)
print("hours = (hour):(minutes):(seconds)")

像这样你可以通过相应的传递来获得时代，年，月，日期等.

Like these you can get era, year, month, date etc. by passing corresponding.
