ios - 在 swift 2 中从 plist 读取时无法创建 NSDictionary

Question

我正在尝试从 plist 中读取信息，( PetList.plist ) 但我不知道为什么失败了。变量路径是正确的，但是 myDict 是 nil，else 部分被执行。我想要做的是从 plist 加载信息，然后将值分配给 pets 数组。
var pets = 宠物 func loadGameData() {

    let path = NSBundle.mainBundle().pathForResource("PetList", ofType: "plist")

    let myDict = NSDictionary(contentsOfFile: path!)

    if let dict = myDict {
        //loading values
        for i in 0..<pets.count {
            pets[i].petName = dict.objectForKey("petName")!.absoluteString!
            pets[i].health = dict.objectForKey("health")!.absoluteString!
            pets[i].experience = dict.objectForKey("experience")!.absoluteString!
            pets[i].hungry = dict.objectForKey("hungry")!.absoluteString!
            pets[i].energy = dict.objectForKey("energy")!.absoluteString!
            pets[i].level = dict.objectForKey("level")!.absoluteString!
            pets[i].status = dict.objectForKey("status")!.absoluteString!
            pets[i].searchKey = dict.objectForKey("searchKey")!.absoluteString!
            pets[i].cleanliness = dict.objectForKey("cleanliness")!.absoluteString!
            pets[i].isChoosed = dict.objectForKey("isChoosed")!.absoluteString!
            pets[i].skill = dict.objectForKey("skill")!.absoluteString!
            pets[i].imageName = dict.objectForKey("imageName")!.absoluteString!
        }
    } else {
        print("WARNING: Couldn't create dictionary from PetList.plist! Default values will be used!")
    }
}

有几个问题。

• 顶级对象是一个数组
• absoluteString 会导致编译错误。
• 必须有一个 Pet 结构或类才能从数组创建实例。

像这样

struct Pet {
  var petName = "", health = "", experience = "", hungry = ""
  var energy = "", level = "", status = "", searchKey = ""
  var cleanliness = "", isChoosed = "", skill = "", imageName = ""
}

var pets = [Pet]()

func loadGameData() {

  let path = NSBundle.mainBundle().pathForResource("PetList", ofType: "plist")
  if let myArray =  NSArray(contentsOfFile: path!) as? [[String:String]] {
    //loading values

    for anItem in myArray {
      var pet = Pet()
      pet.petName = anItem["petName"]!
      pet.health = anItem["health"]!
      pet.experience = anItem["experience"]!
      pet.hungry = anItem["hungry"]!
      pet.energy = anItem["energy"]!
      pet.level = anItem["level"]!
      pet.status = anItem["status"]!
      pet.searchKey = anItem["searchKey"]!
      pet.cleanliness = anItem["cleanliness"]!
      pet.isChoosed = anItem["isChoosed"]!
      pet.skill = anItem["skill"]!
      pet.imageName = anItem["imageName"]!
      pets.append(pet)
    }
  } else {
    print("WARNING: Couldn't create array from PetList.plist! Default values will be used!")
  }
}
