我是新來的斯威夫特的世界，我不知道我在做什麼！我正在開發一個應用程序，用於從服務器中拉取電子郵件列表以及附件（如果電子郵件有附件）。我遇到了兩個問題。第一個問題是，我似乎無法從NS Dictionary轉換爲NSArray，並且我花了幾天的時間在StackOverflow上搜索一個無效的解決方案，所以也許是我編寫代碼的方式？接下來的問題是，我必須根據NSDictionary中的ID拉取電子郵件的URL。該ID也是每個電子郵件URL的最後一部分，但我不知道甚至開始接近這個概念。的NSDictionary的NSArray來提供動態網址發現
對不起，聽起來有需要的，但我不是通過貿易軟件開發人員，甚至在訓練中（我是一個資深的大學的網絡/系統），所以我有問題纏繞我的頭解決此編程邏輯我不明白。下面是我設法至今（注放在一起代碼：它打破了在線路72 self.Table = JsonWithDatos as! NSArray：
import Foundation
import UIKit
class TableViewControllerNews: UITableViewController {
@IBOutlet weak var searchBar: UISearchBar!
@IBOutlet weak var Submit: UIView!
var Table:NSArray = []
override func viewDidLoad() {
super.viewDidLoad()
CallWebService()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
func CallWebService()
{
let UrlApi = "********"
let Url = NSURL(string: UrlApi)
let Session = NSURLSession.sharedSession()
let Work = Session.dataTaskWithURL(Url!, completionHandler: { dataTask, response, error -> Void in
if (error != nil)
{
print(error)
}
let datos:NSData = NSData(data: dataTask!)
print(datos)
print(response)
self.ParseoDataToJson(datos)
})
Work.resume()
}
func ParseoDataToJson(datos:NSData)
{
do {
let JsonWithDatos:AnyObject! = try NSJSONSerialization.JSONObjectWithData(datos, options: NSJSONReadingOptions.MutableContainers)
print(JsonWithDatos)
struct AnnouncementList {
var ID: NSArray?
var Subject: NSArray?
init(announcementObject: AnyObject) {
// announcements = (announcementObject["Announcements"] as NSArray)
if let announcements = announcementObject["Announcements"] as? NSArray {
ID = (announcements.valueForKey("ID") as! NSArray)
Subject = (announcements.valueForKey("Subject") as! NSArray)
}
}
}
self.Table = JsonWithDatos as! NSArray
print(self.Table)
print(self.Table.count)
self.tableView.reloadData()
}
catch {
print("Error")
}
}
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.Table.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell
let item = self.Table[indexPath.row] as! [String : String]
cell.textLabel!.text = item["Subject"]
return cell
}
override func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
return false
}
}
