ios - UITabelView 中带有 API 数据的部分

Question

我在 swift 2.x 和 xcode 7.x 中工作，我被 tabelviews 和 api 数据困住了。我看的每个地方都需要有 2 个数组，一个用于我的对象，一个用于该部分。我当前的代码是:

 //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，我将其解包并将其设置在事件集合中。一个事件的例子是:

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，它会将 tabelview 分成几部分，月份名称作为标题标题。但我需要将事件分类到正确的月份。例如，6 月的那个只需要在 6 月出现一次，而当我在 6 月添加一个 otherwone 时，它​​需要去那里。

所以表格 View 看起来像这样:

六月

一月的细胞

6 月的单元格

一月

一月的细胞

6 月的单元格

我想要的是

六月:

6 月的单元格

一月

一月的细胞

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!感谢您的任何回复。

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 2 个问题:

1. 如何在月份数组中对数据进行排序
2. 如何从 TableView 中的数组获取数据？

Answer 1

您的方法很好，只需稍作修改。基本上你需要按月和单独的日期数组维护一个与会者，这是如何完成的，

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

所以现在您可以使用月份数组来获取 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
}

希望对您有所帮助!
