Question

我在swift 2.x和xcode 7.x中工作，我遇到了tabelviews和api数据。每一个我看起来我需要有2个数组的一个与我的对象和一个用于该部分。我目前的代码是：

 //MARK: Setting up the tableview
    func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return eventsCollection.count
    }
    func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
        let eventDate = self.eventsCollection[section].startDate
        let month = Utility.sharedInstance.convertToDateStringMonth(eventDate)
        return month
    }

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return self.eventsCollection.count
}


func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {

    return 70;
}


func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    return
}


func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell: EventCellView!
    cell = self.calenderTabelView.dequeueReusableCellWithIdentifier("EventCellView") as! EventCellView
    cell.dayNameLabel.text = Utility.sharedInstance.getDayOfWeek(self.eventsCollection[indexPath.row].startDate)
    cell.dayNumberLabel.text = Utility.sharedInstance.convertToDataDay(self.eventsCollection[indexPath.row].startDate)
    cell.NewLabel.text = self.eventsCollection[indexPath.row].Name
    return cell
}

当我获取数据时，我将其解包并在eventcollection中设置它。事件的一个例外是：

注意：这是API响应。

AllDay = 1;

Attendees =     (
); <as array>
Description = "Test Evenment"; <as string>
EndDate = "2017-02-03T23:59:59+00:00"; <as string>
ID = 173; <as int or string>
Name = "Test evenement"; <string>
StartDate = "2016-11-01T00:00:00+00:00"; <string>
VenueName = "Appbakkers HQ";} <string>

当我运行代码时，它将tabelview分为以月份名称作为标题标题的部分。但我需要将事件分类到正确的月份。例如，6月份只需要在六月出现一次，当我在六月添加一个其他人时，它需要去那里。

所以tableview看起来像这样：

六月

1月的细胞

6月的细胞

一月

1月的细胞

6月的细胞

我想要的是

六月：

6月的细胞

一月

1月的细胞

the function getDayOfWeek -> monday thueseday ,etc as a string
the function convertToDataDay -> 1 - 31 as a string
the function convertToDateStringMonth -> june, juli, etc. as string

任何输入都会帮助我！感谢您的回复。

附加：

class Event: NSObject {
    //the event class
    var id:Int = 0
    var Description: String = ""
    var endDate: String = ""
    var Name: String = ""
    var startDate: String = ""
    var venueName: String = ""
//    var Attendees: NSDictionary = [:] havent figuerd this part out also
}

    func mapComment(responseObject: AnyObject) -> Event{

        let EventObject = Event()

//        let andenteesObject = responseObject["Attendees"]

        if let ID = responseObject["id"] as? Int {
            EventObject.id = ID
        } else if let ID = responseObject["id"] as? String {
            EventObject.id = Int(ID)!
        }

        if let despription = responseObject["Description"] as? String{
            EventObject.Description = despription
        }
        if let startDate = responseObject["StartDate"] as? String{
            EventObject.startDate = startDate
        }
        if let endDate = responseObject["EndDate"] as? String{
            EventObject.endDate = endDate
        }
        if let name = responseObject["Name"] as? String{
            EventObject.Name = name
        }
//        if let attendees = andenteesObject as? NSDictionary{
//            EventObject.Attendees = attendees
//        }
        return EventObject
    }
}

所以我实际上有两个问题：

如何对数据和月份数组进行排序
如何在tableview中从该数组中获取数据？

Answer 1

您的方法很好，几乎不需要修改。基本上你需要按月保持一个与会者和单独的日期数组，这是如何做到的，

var eventsByMonth : [String : [Event]] = [:]

// store as date, its easy to sort (but anyway you like) 
var months = [NSDate]()

// iterate over response and store according to month,
for event in events {

  //convert the string to date (you can find it easily)
  let startDate = convertStringtoDate(event.startDate)

  months.append(startDate)

  // now split events by months 
  let month = Utility.sharedInstance.convertToDateStringMonth(event.StartDate)

  var temp = eventsByMonth[month] ?? []
  temp.append(event)

  eventsByMonth[month] = temp
}

months = sortDate(months) // sort anyway you like

所以现在你可以使用months数组来获取tableView的计数，如下所示，

func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return months.count
}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    let month =  months[section]

    guard let monthEvents = eventsByMonth[month] else {
        return 0
    }

    return monthEvents.count
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let month =  months[section]
    let monthEvents = events[month]!

    let event = monthEvents[indexPath.row]

    // configure your cell
}

希望有所帮助！
