【问题描述】：
我正在尝试将我的代码更新到 iOS12。以下是我的代码：
class CurrentGameState: NSObject, NSSecureCoding {
static var supportsSecureCoding: Bool = true
var currentTest1 = Int()
var currentUnitPositionColumn = [String: Int]()
static var currentGameStatus = CurrentGameState(unit: "init", test: 1, column: -1)
var currentTest1 = Int()
var currentUnitPositionColumn = [String: Int]()
init(unit: String, test: Int, column: Int) {
currentTest1 = test
currentUnitPositionColumn[unit] = column
}
func encode(with aCoder: NSCoder) {
aCoder.encode(currentTest1, forKey: test1)
aCoder.encode(currentUnitPositionColumn, forKey: currentColumn)
}
required init(coder aDecoder: NSCoder) {
self.currentTest1 = aDecoder.decodeInteger(forKey: test1)
self.currentUnitPositionColumn = aDecoder.decodeObject(forKey: currentColumn) as! [String : Int]
}
extension PersistData {
func newSaveMatchInfo(saveType: GlobalConstants.saveType) {
let gameDataFile = "GameData" + String(describing: saveType)
if let url = getFileURLInAppDocumentDirectory(fileName: gameDataFile) {
do{
let archive = try NSKeyedArchiver.archivedData(withRootObject: CurrentGameState.currentGameStatus, requiringSecureCoding: true)
try archive.write(to: url)
}catch{
print("!!!!!Error saving Game data == \(error)")
}
}
}
func newLoadMatchInfo(saveType: GlobalConstants.saveType) {
let gameDataFile = "GameData" + String(describing: saveType)
guard let gameData = try? Data(contentsOf: getFileURLInAppDocumentDirectory(fileName: gameDataFile)!),
let gameInfo = try? NSKeyedUnarchiver.unarchivedObject(ofClasses: [CurrentGameState.self], from: gameData as Data ) else {
print("!!!!!Error gameInfo = try? NSKeyedUnarchiver.unarchivedObject failed ")
return
}
CurrentGameState.currentGameStatus = gameInfo as!
}
}
当我运行此代码时，NSKeyedUnarchiver 适用于 Int currentTest1，但在遇到字典 currentUnitPositionColumn 时返回 nil。下面显示的 NSKeyedUnarchiver 旧代码工作正常，但 unarchiveObject(withFile: 在 iOS12 中已弃用。
func loadMatchInfo(saveType: GlobalConstants.saveType) {
let gameDataFile = "GameData" + String(describing: saveType)
if let url = getFileURLInAppDocumentDirectory(fileName: gameDataFile) {
if let gameData = NSKeyedUnarchiver.unarchiveObject(withFile: url.path) as? CurrentGameState {
CurrentGameState.currentGameStatus = gameData
}
}
}
Dictionary 的某些内容不适用于我的新代码。任何帮助将不胜感激。
