func date() -> String {
return NSDateFormatter.localizedStringFromDate(NSDate(), dateStyle: NSDateFormatterStyle.ShortStyle, timeStyle: NSDateFormatterStyle.MediumStyle)
}
var date = date() // 2016. 5. 13. 오전 4:45:16
上面的代码,每次我调用date()
时,date都会获得韩国当前的日期值我希望从NSDate()刷新新值,然后将刷新值插入varibles,如下面的代码
var yearMonDay = "2016. 5. 13"
var hourMinSec = "오전 4:45:16"
嗯有没有方法可以将NSDate()划分为如下代码所示的部分?
yearMonDay = NSDate().?? // refresh date "year: month: day"
hourMinSec = NSDate().?? // refresh date "am/fm hour:minute:second

可以使用NSCalendar的组件
来分割像小时这样的组件let today = NSDate()
let calendar = NSCalendar(identifier: NSCalendarIdentifierGregorian)!
let components = calendar.components([.Year, .Month, .Day, .Hour, .Minute, .Second], fromDate: today)
print("\(components.month) \(components.day) \(components.year)")
print("\(components.hour) \(components.minute) \(components.second)")
使用NSDate格式化程序,您可以找到名称
let formatter = NSDateFormatter()
let monthName = formatter.monthSymbols[components.month-1]
print(monthName)

您可以使用NSDateFormatterStyle:
return Promise.map(BigArray, function(innerArray) {
return Promise.all(innerArray);
})
.then(function(finishedArray) {
// code after all 60k promises have been resolved comes here
console.log("done");
});
