【问题描述】:
我正在尝试将纯 java 代码转换为 swift。但是,我在设置当前时间时遇到了一点问题。我可以以毫秒为单位获取当前时间。但我无法设置当前时间。有什么帮助吗?
这是我的代码
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
let now = NSDate()
var auctionDate = [String:String]()
let dateFormatter = NSDateFormatter()
dateFormatter.locale = NSLocale(localeIdentifier: "en_US")
var sdfDDMMYYYYEEE : NSDateFormatter!
sdfDDMMYYYYEEE.dateFormat = "dd/MM/yyyy (EEE)"
var sdfDDMMYYYY : NSDateFormatter!
sdfDDMMYYYY.dateFormat = "dd/MM/yyyy"
var sdfEEE : NSDateFormatter!
sdfEEE.dateFormat = "EEE"
// This is how i get the current time
println((now.timeIntervalSince1970)*1000 + 86400000.00)
for var i = 0; i < 5; i++ {
if sdfEEE.stringFromDate(now) == "Sun" {
// This is where i have to set my time with that ((now.timeIntervalSince1970)*1000 + 86400000.00)
i--;
continue;
}
auctionDate[(sdfDDMMYYYY.stringFromDate(now) as String)] = (sdfDDMMYYYYEEE.stringFromDate(now) as String)
// Here too I have to set my time
}
println(dateFormatter.stringFromDate(now))
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
这是我要转换成 swift 代码的 java 代码
import java.text.*;
import java.util.*;
public class DateTest{
Date now = new Date();
Map<String, String> myDate = new LinkedHashMap<String, String>();
myDate.put("", "All");
SimpleDateFormat sdfDDMMYYYYEEE = new SimpleDateFormat("dd/MM/yyyy (EEE)");
SimpleDateFormat sdfDDMMYYYY = new SimpleDateFormat("dd/MM/yyyy");
SimpleDateFormat sdfEEE = new SimpleDateFormat("EEE");
for (int i = 0; i < 5; i++) {
if (sdfEEE.format(now).equals("Sun")) {
now.setTime(now.getTime() + 86400000);
i--;
continue;
}
myDate.put(sdfDDMMYYYY.format(now), sdfDDMMYYYYEEE.format(now));
now.setTime(now.getTime() + 86400000);
}
}
在 swift 中设置当前时间的任何帮助。我几乎接近我的答案。

init(timeIntervalSince1970:) -
谢谢先生。但是,我还是想不通。;(
