從值字典獲取數組

Question

我有一本字典，我需要將其轉換爲數組，但無法完成實現。在InterfaceController值

字典...在Event類值的

var receivedData = Array<Dictionary<String, String>>() 



func session(session: WCSession, didReceiveUserInfo userInfo: [String : AnyObject]) { 

    if let tColorValue = userInfo["TeamColor"] as? String, let matchValue = userInfo["Matchup"] as? String { 
     receivedData.append(["TeamColor" : tColorValue , "Matchup" : matchValue]) 

     let eventsList = Event.eventsListFromValues(receivedData) 

     for eventM in eventsList { 
      NSLog("Event Match: %@", eventM.eventMatch) 
     } 

    } else { 
     print("tColorValue and matchValue are not same as dictionary value") 
    } 

} 

過程詞典：

class func eventsListFromValues(values: Array<Dictionary<String, String>>) -> Array<Event> { 
     var array = Array<Event>() 

     for eventValues in values { 
      let event = Event(dataDictionary: eventValues) 
      array.append(event) 
     } 

     return array 
    } 

} 

無法弄清楚這部分...使用陣列設置在setupTable表：

func doTable() { 

      // ...get array of `match`s for use in table set up 

      // ...Then set number of Rows 
      // ...Then iterate thru the array 
        for var i = 0; i < self.rowTable.numberOfRows; i++ { 
         var row = self.rowTable.rowControllerAtIndex(i) 
         // ...setup text label 
        } 
    } 

編輯：澄清

doTable將獲得收到的任何match s並將其顯示在表中。所以我認爲我應該做的是獲得一個match s的數組，然後使用它們來設置表中的文本標籤。

編輯2：這是我迄今爲止

class InterfaceController: WKInterfaceController, WCSessionDelegate { 

    class EventSO { 
     var teamColor:String! 
     var matchup:String! 

     init(dataDictionary:[String:String]) { 
      teamColor = dataDictionary["teamColor"] 
      matchup = dataDictionary["Matchup"] 
     } 
    } 

    var receivedDataSO = [Event]() 

    var tColorValueSO = "Red" 
    var matchValueSO = "someString" 

    var eventSO = EventSO(dataDictionary: ["teamColor": tColorValueSO, "Matchup": matchValueSO]) 

故事板：

Answer 1

下面的代碼做了一些假設和習慣有直接關係，因爲我又不是對WatchKit和其他代碼非常熟悉。

我不認爲你真的需要eventListFromValues方法，我是在XCode的一個操場上完成的。

class Event { 
    var teamColor:String! 
    var matchup:String! 

    init(dataDictionary:[String:String]) { 
     teamColor = dataDictionary["teamColor"] 
     matchup = dataDictionary["Matchup"] 
    } 
} 

var receivedData = [Event]() 

var tColorValue = "Red" 
var matchValue = "someString" 

var event = Event(dataDictionary: ["teamColor": tColorValue, "Matchup": matchValue]) 

receivedData.append(event) 

func doTable(events: [Event]) { 
    myTable.setNumberOfRows(events.count, withRowType: "someRowController") 

    for (index, evt) in events { 
      let row = myTable.rowControllerAtIndex(index) as someRowController 
      row.interfaceLabel.setText(evt.teamColor) 
    } 
} 

因此，使用上面的代碼，你應該能夠去除eventListFromValues功能，當您收到用戶信息創建接收的值一個新的Event對象並把它添加到數組的結尾。

然後，您的doTable函數將對數組進行迭代，並根據行上的數據設置表的UI部分。

因此，要使用此代碼在您的特定情況下，你可能會做這樣的事情：

class InterfaceController: WKInterfaceController, WCSessionDelegate { 

    var evnts = [Event]() 

    func session(session: WCSession, didReceiveUserInfo userInfo: [String : AnyObject]) { 

     if let tColorValue = userInfo["TeamColor"] as? String, let matchValue = userInfo["Matchup"] as? String { 
      var event = Event(dataDictionary: ["teamColor": tColorValue, "Matchup": matchValue]) 
      events.append(event) 
      doTable() 
     } else { 
      print("tColorValue and matchValue are not same as dictionary value") 
     } 

    } 

    func doTable() { 
     myTable.setNumberOfRows(events.count, withRowType: "someRowController") 

     for (index, evt) in events { 
      let row = myTable.rowControllerAtIndex(index) as someRowController 
      row.interfaceLabel.setText(evt.teamColor) 
     } 
    } 
}
