如何获取当前时间作为日期时间 [英] How to get the current time as datetime

问题描述

刚从操场开始。我正在尝试创建一个简单的应用程序。

Just started with the playground. I'm trying to create a simple app.

我创建了一个这样的日期对象：

I've created a date object like this:

var date = NSDate()

如何获取当前小时？在其他语言中，我可以这样做：

How can I get the current hour? In other languages I can do something like this:

var hour = date.hour

但是我找不到任何属性/方法。我找到了一个方法， dateWithCalendarFormat 。我应该用吗如果是，那么如何？

But I can't find any properties/methods like that. I've found a method, dateWithCalendarFormat. Should I use that? If so, HOW?

推荐答案

Swift 3更新

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

我这样做：

I do this:

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

在objective-c 如何从NSDate获取小时和分钟？
