Swift를 사용하여 plist 파일의 새 배열 데이터를 NSDictionary에 추가하는 방법

Question

탐색 데이터를 저장하기위한 plist 파일 ("myAwayList.plist")이 있습니다. 다음 나 ...

<dict> 
<key>Locations</key> 
<array> 
    <dict> 
     <key>Name</key> 
     <string>Sydney City Centre</string> 
     <key>Address</key> 
     <string>Centrepoint Tower</string> 
     <key>Lat</key> 
     <string>-33.870451</string> 
     <key>Lon</key> 
     <string>151.208771</string> 
    </dict> ... 

I 성공적으로 로딩하고 다음으로 내부에 배열 된 데이터를 사용할 수있다 .. 주 사전에 배열

 let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true) as NSArray 
    let documentsDirectory = paths.objectAtIndex(0)as NSString 
    let path = documentsDirectory.stringByAppendingPathComponent("myAwayList.plist") 
    let fileManager = NSFileManager.defaultManager() 
    // Check if file exists 
    if(!fileManager.fileExistsAtPath(path)) 
    { 
     // If it doesn't, copy it from the default file in the Resources folder 
     let bundle = NSBundle.mainBundle().pathForResource("myAwayList", ofType: "plist") 
     fileManager.copyItemAtPath(bundle!, toPath: path, error:nil) 
     println("File did not exist! Default copied...") 
    } 
    let dict = NSDictionary(contentsOfFile: path)! 
    let mySavedLocations: AnyObject = dict.objectForKey("Locations")! 
    println("plist all: \(mySavedLocations)") 
    if let nsArray:NSArray = mySavedLocations as? NSArray{ 
     for var loadCount = 0; loadCount < mySavedLocations.count; ++loadCount { 
      var locationDict:AnyObject = nsArray[loadCount] // loading array data at index 
      let arrayName = locationDict["Name"] as AnyObject? as String 
      let arrayAddress = locationDict["Address"] as AnyObject? as String 
      let arrayLat = locationDict["Lat"] as AnyObject? as String 
      let arrayLon = locationDict["Lon"] as AnyObject? as String 
      awaydatalist.append(AwayData(name:arrayName, address:arrayAddress, lat:arrayLat, lon:arrayLon)) // This is a list array used to display the loaded data on a ViewController 
     } 
    } 

I를 문자열 변수의 사전 중첩 한 이제 다른 데이터 행과 함께 배열을 내부에 추가하고 plist 파일에 다시 쓰기를 원하지만이를 수행 할 방법을 찾을 수 없습니다. 제발 조언 해 줘? 여기에 크리스

let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true) as NSArray 
    let documentsDirectory = paths.objectAtIndex(0)as NSString 
    let path = documentsDirectory.stringByAppendingPathComponent("myAwayList.plist") 


    let fileManager = NSFileManager.defaultManager() 
    // Check if file exists 
    if(!fileManager.fileExistsAtPath(path)) 
    { 
     // If it doesn't, copy it from the default file in the Resources folder 
     let bundle = NSBundle.mainBundle().pathForResource("myAwayList", ofType: "plist") 
     fileManager.copyItemAtPath(bundle!, toPath: path, error:nil) 
     println("File did not exist! Default copied...") 
    } 

    let dict = NSMutableDictionary(contentsOfFile: path)! 

    let mySavedLocations: AnyObject = dict.objectForKey("Locations")! 

    println("plist all: \(mySavedLocations)") 

    if let nsArray:NSArray = mySavedLocations as? NSArray 
    { 
     for var loadCount = 0; loadCount < mySavedLocations.count; ++loadCount 
     { 
      var locationDict:AnyObject = nsArray[loadCount] // loading array data at index 
      let arrayName = locationDict["Name"] as AnyObject? as String 
      let arrayAddress = locationDict["Address"] as AnyObject? as String 
      let arrayLat = locationDict["Lat"] as AnyObject? as String 
      let arrayLon = locationDict["Lon"] as AnyObject? as String 
      // awaydatalist.append(AwayData(name:arrayName, address:arrayAddress, lat:arrayLat, lon:arrayLon)) // This is a list array used to display the loaded data on a ViewController 
     } 
    } 

    //Convert AnyObject to NSMutableArray 
    var twDataArray = (mySavedLocations as NSMutableArray) as NSMutableArray 

    //Create a new Dictionary 
    let airports: [String: String] = ["Name": "Toronto Pearson", "Address": "Dublin","Lat":"23.23","Lon":"78.89"] 

    //add dictionary to array 
    twDataArray.addObject(airports) 

    //set the new array for location key 
    dict.setObject(mySavedLocations, forKey: "Locations") 

    //update the plist 
    dict.writeToFile(path, atomically: true) 

이 코드는 위치 배열 안에 새 사전을 추가 PLIST 파일에 저장된 배열 안에 새 사전 추가하는 코드입니다.
