Question

我正在建立一个快速的游戏并且需要建立一个班级。我的代码适用于我班级中的所有元素，但不适用于此。

func saveInformationMember(){

var MembersDefaultName = NSUserDefaults.standardUserDefaults()
MembersDefaultName.setValue(globalCurrentMembers, forKey: "globalCurrentMembersData")
MembersDefaultName.synchronize()

}

GlobalCurrentMembers是Member的数组，如下所示：

class Member {
var image = String ()
var name = String ()
var progression = Int()
var round = Int()
var level = Int()
var imageProgression = [UIButton]()


func Init(){
    image = "default.png"
    name = "default"
    progression = 0
    round = 0
    level = 0
}

提前帮忙。

Answer 1

要以这种方式保存您的课程，Member需要符合NSCoding协议。

Answer 2

对Aaron Brager来说是回应。这是回复：

func saveInformationMember(){
let data = NSKeyedArchiver.archivedDataWithRootObject(globalCurrentMembers)
NSUserDefaults.standardUserDefaults().setObject(data, forKey: "member")}

func loadInformationMember(){

if let data = NSUserDefaults.standardUserDefaults().objectForKey("member") as? NSData {
globalCurrentMembers = NSKeyedUnarchiver.unarchiveObjectWithData(data) as [Member]
}

我的班级：

class Member : NSObject, NSCoding {
var image = String ()
var name = String ()
var progression = Int()
var round = Int()
var level = Int()
var imageProgression = [UIButton]()


func initiation(){
    image = "default.png"
    name = "default"
    progression = 0
    round = 0
    level = 0
}

required convenience init(coder decoder: NSCoder) {
    self.init()
    self.image = decoder.decodeObjectForKey("image") as String!
    self.name = decoder.decodeObjectForKey("name") as String!
    self.progression = decoder.decodeIntegerForKey("progression") as Int!
    self.round = decoder.decodeIntegerForKey("round") as Int!
    self.level = decoder.decodeIntegerForKey("level") as Int!
}

func encodeWithCoder(coder: NSCoder) {
    coder.encodeObject(self.image, forKey: "image")
    coder.encodeObject(self.name, forKey: "name")
    coder.encodeInt(Int32(self.progression), forKey: "progression")
    coder.encodeInt(Int32(self.round), forKey: "round")
    coder.encodeInt(Int32(self.level), forKey: "level")
}}

使用NSuserdefaults在Swift中发出SIGABRT信号
