# 特性:
- 把 JSON 映射成对象
- 把对象映射 JSON
- 支持嵌套对象 (单独的成员变量、在数组或字典中都可以)
- 在转换过程支持自定义规则
- 支持结构体( Struct
- [Immutable support](#immutablemappable-protocol-beta) (目前还在 beta )
# 基础使用方法
为了支持映射,类或者结构体只需要实现```Mappable```协议。这个协议包含以下方法:
```swift
init?(map: Map)
mutating func mapping(map: Map)
```
ObjectMapper使用自定义的```<-``` 运算符来声明成员变量和 JSON 的映射关系。
```swift
class User: Mappable {
var username: String?
var age: Int?
var weight: Double!
var array: [AnyObject]?
var dictionary: [String : AnyObject] = [:]
var bestFriend: User? // 嵌套的 User 对象
var friends: [User]? // Users 的数组
var birthday: NSDate?
required init?(map: Map) {
}
// Mappable
func mapping(map: Map) {
username <- map["username"]
age <- map["age"]
weight <- map["weight"]
array <- map["arr"]
dictionary <- map["dict"]
bestFriend <- map["best_friend"]
friends <- map["friends"]
birthday <- (map["birthday"], DateTransform())
}
}
struct Temperature: Mappable {
var celsius: Double?
var fahrenheit: Double?
init?(map: Map) {
}
mutating func mapping(map: Map) {
celsius <- map["celsius"]
fahrenheit <- map["fahrenheit"]
}
}
```
一旦你的对象实现了 `Mappable`, ObjectMapper就可以让你轻松的实现和 JSON 之间的转换。
把 JSON 字符串转成 model 对象:
```swift
let user = User(JSONString: JSONString)
```
把一个 model 转成 JSON 字符串:
```swift
let JSONString = user.toJSONString(prettyPrint: true)
```
也可以使用`Mapper.swift`类来完成转换(这个类还额外提供了一些函数来处理一些特殊的情况:
```swift
// 把 JSON 字符串转成 Model
let user = Mapper<User>().map(JSONString: JSONString)
// 根据 Model 生成 JSON 字符串
let JSONString = Mapper().toJSONString(user, prettyPrint: true)
```
ObjectMapper支持以下的类型映射到对象中:
- `Int`
- `Bool`
- `Double`
- `Float`
- `String`
- `RawRepresentable` (枚举)
- `Array<AnyObject>`
- `Dictionary<String, AnyObject>`
- `Object<T: Mappable>`
- `Array<T: Mappable>`
- `Array<Array<T: Mappable>>`
- `Set<T: Mappable>`
- `Dictionary<String, T: Mappable>`
- `Dictionary<String, Array<T: Mappable>>`
- 以上所有的 Optional 类型
- 以上所有的隐式强制解包类型(Implicitly Unwrapped Optional
## `Mappable` 协议
#### `mutating func mapping(map: Map)`
所有的映射最后都会调用到这个函数。当解析 JSON 时,这个函数会在对象创建成功后被执行。当生成 JSON 时就只有这个函数会被对象调用。
#### `init?(map: Map)`
这个可失败的初始化函数是 ObjectMapper 创建对象的时候使用的。开发者可以通过这个函数在映射前校验 JSON 。如果在这个方法里返回 nil 就不会执行 `mapping` 函数。可以通过传入的保存着 JSON 的 `Map` 对象进行校验:
```swift
required init?(map: Map){
// 检查 JSON 里是否有一定要有的 "name" 属性
if map.JSONDictionary["name"] == nil {
return nil
}
}
```
## `StaticMappable` 协议
`StaticMappable` 是 `Mappable` 之外的另一种选择。 这个协议可以让开发者通过一个静态函数初始化对象而不是通过 `init?(map: Map)`。
注意: `StaticMappable` 和 `Mappable` 都继承了 `BaseMappable` 协议。 `BaseMappable` 协议声明了 `mapping(map: Map)` 函数。
#### `static func objectForMapping(map: Map) -> BaseMappable?`
ObjectMapper 使用这个函数获取对象后进行映射。开发者需要在这个函数里返回一个实现 `BaseMappable` 对象的实例。这个函数也可以用于:
- 在对象进行映射前校验 JSON
- 提供一个缓存过的对象用于映射
- 返回另外一种类型的对象(当然是必须实现了 BaseMappable)用于映射。比如你可能通过检查 JSON 推断出用于映射的对象 ([看这个例子](https://github.com/Hearst-DD/ObjectMapper/blob/master/ObjectMapperTests/ClassClusterTests.swift#L62))。
如果你需要在 extension 里实现 ObjectMapper,你需要选择这个协议而不是 `Mappable` 。
## `ImmutableMappable` Protocol
使用 `ImmutableMappable` 可以映射不可变的属性。下面的表格展示了 `ImmutableMappable` 和 `Mappable` 的不同:
<table>
<tr>
<th>ImmutableMappable</th>
<th>Mappable</th>
</tr>
<tr>
<th colspan="2">Properties</th>
</tr>
<tr>
<td>
<pre>
<strong>let</strong> id: Int
<strong>let</strong> name: String?
</pre>
</td>
<td>
<pre>
var id: Int!
var name: String?
</pre>
</td>
</tr>
<tr>
<th colspan="2">JSON -> Model</th>
</tr>
<tr>
<td>
<pre>
init(map: Map) <strong>throws</strong> {
id = <strong>try</strong> map.value("id")
name = <strong>try?</strong> map.value("name")
}
</pre>
</td>
<td>
<pre>
mutating func mapping(map: Map) {
id <- map["id"]
name <- map["name"]
}
</pre>
</td>
</tr>
<tr>
<th colspan="2">Model -> JSON</th>
</tr>
<tr>
<td>
<pre>
mutating func mapping(map: Map) {
id <strong>>>></strong> map["id"]
name <strong>>>></strong> map["name"]
}
</pre>
</td>
<td>
<pre>
mutating func mapping(map: Map) {
id <- map["id"]
name <- map["name"]
}
</pre>
</td>
</tr>
<tr>
<th colspan="2">Initializing</th>
</tr>
<tr>
<td>
<pre>
<strong>try</strong> User(JSONString: JSONString)
</pre>
</td>
<td>
<pre>
User(JSONString: JSONString)
</pre>
</td>
</tr>
</table>
#### `init(map: Map) throws`
这个可能抛出异常的初始化函数用于在提供的 `Map` 里映射不可变属性。每个不可变的初始化属性都要在这个初始化函数里初始化。
当发生下列情况时初始化函数会抛出一个错误:
- `Map` 根据提供的键名获取不到对应值
- `Map` 使用 `Transform` 后没有得到值
`ImmutableMappable` 使用 `Map.value(_:using:)` 方法从 `Map` 中获取值。因为可能抛出异常,这个方法在使用时需要使用 `try` 关键字。 `Optional` 的属性可以简单的用 `try?` 处理。
```swift
init(map: Map) throws {
name = try map.value("name") // throws an error when it fails
createdAt = try map.value("createdAt", using: DateTransform()) // throws an error when it fails
updatedAt = try? map.value("updatedAt", using: DateTransform()) // optional
posts = (try? map.value("posts")) ?? [] // optional + default value
}
```
#### `mutating func mapping(map: Map)`
这个方法是在 Model 转回 JSON 时调用的。因为不可变的属性不能被 `<-` 映射,所以映射回来时需要使用 `>>>` 。
```swift
mutating func mapping(map: Map) {
name >>> map["name"]
createdAt >>> (map["createdAt"], DateTransform())
updatedAt >>> (map["updatedAt"], DateTransform())
posts >>> map["posts"]
}
```
# 轻松映射嵌套对象
ObjectMapper 支持使用点语法来轻松实现嵌套对象的映射。比如有如下的 JSON 字符串:
```json
"distance" : {
"text" : "102 ft",
"value" : 31
}
```
你可以通过这种写法直接访问到嵌套对象:
```swift
func mapping(map: Map) {
distance <- map["distance.value"]
}
```
嵌套的键名也支持访问数组中的值。如果有一个返回的 JSON 是一个包含 distance 的数组,可以通过这种写法访问:
```
distance <- map["distances.0.value"]
```
如果你的键名刚好含有 `.` 符号,你需要特别声明关闭上面提到的获取嵌套对象功能:
```swift
func mapping(map: Map) {
identifier <- map["app.identifier", nested: false]
}
```
如果刚好有嵌套的对象的键名还有 `.` ,可以在中间加入一个自定义的分割符([#629](https://github.com/Hearst-DD/ObjectMapper/pull/629):
```swift
func mapping(map: Map) {
appName <- map["com.myapp.info->com.myapp.name", delimiter: "->"]
}
```
这种情况的 JSON 是这样的:
```json
"com.myapp.info" : {
"com.myapp.name" : "SwiftOldDriver"
}
```
# 自定义转换规则
ObjectMapper 也支持在映射时自定义转换规则。如果要使用自定义转换,创建一个 tuple(元祖)包含 ```map["field_name"]``` 和你要使用的变换放在 ```<-``` 的右边:
```swift
birthday <- (map["birthday"], DateTransform())
```
当解析 JSON 时上面的转换会把 JSON 里面的 Int 值转成一个 NSDate ,如果是对象转为 JSON 时,则会把 NSDate 对象转成 Int 值。
只要实现```TransformType``` 协议就可以轻松的创建自定义的转换规则:
```swift
public protocol TransformType {
associatedtype Object
associatedtype JSON
func transformFromJSON(_ value: Any?) -> Object?
func transformToJSON(_ value: Object?) -> JSON?
}
```
### TransformOf
大多数情况下你都可以使用框架提供的转换类 ```TransformOf``` 来快速的实现一个期望的转换。 ```TransformOf``` 的初始化需要两个类型和两个闭包。两个类型声明了转换的目标类型和源类型,闭包则实现具体转换逻辑。
举个例子,如果你想要把一个 JSON 字符串转成 Int ,你可以像这样使用 ```TransformOf```
```swift
let transform = TransformOf<Int, String>(fromJSON: { (value: String?) -> Int? in
// 把值从 String? 转成 Int?
return Int(value!)
}, toJSON: { (value: Int?) -> String? in
// 把值从 Int? 转成 String?
if let value = value {
return String(value)
}
return nil
})
id <- (map["id"], transform)
```
这是一种更省略的写法:
```swift
id <- (map["id"], TransformOf<Int, String>(fromJSON: { Int($0!) }, toJSON: { $0.map { String($0) } }))
```
# 继承
实现了 ```Mappable``` 协议的类可以容易的被继承。当继承一个 mappable 的类时,使用这样的结构:
```swift
class Base: Mappable {
var base: String?
required init?(map: Map) {
}
func mapping(map: Map) {
base <- map["base"]
}
}
class Subclass: Base {
var sub: String?
required init?(map: Map) {
super.init(map)
}
override func mapping(map: Map) {
super.mapping(map)
sub <- map["sub"]
}
}
```
注意确认子类中的实现调用了父类中正确的初始化器和映射函数。
# 泛型对象
ObjectMapper 可以处理泛型只要这个泛型也实现了`Mappable`协议。看这个例子:
```swift
class Result<T: Mappable>: Mappable {
var result: T?
required init?(map: Map){
}
func mapping(map: Map) {
result <- map["result"]
}
}
let result = Mapper<Result<User>>().map(JSON)
```
# 映射时的上下文对象
`Map` 是在映射时传入的对象,带有一个 optional `MapContext` 对象,开发者可以通过使用这个对象在映射时传入一些信息。
为了使用这个特性,需要先创建一个对象实现了 `MapContext` 协议(这个协议是空的),然后在初始化时传入 `Mapper` 中。
```swift
struct Context: MapContext {
var importantMappingInfo = "映射时需要知道的额外信息"
}
class User: Mappable {
var name: String?
required init?(map: Map){
}
func mapping(map: Map){
if let context = map.context as? Context {
// 获取到额外的信息
}
}
}
let context = Context()
let user = Mapper<User>(context: context).map(JSONString)
```
# ObjectMapper + Alamofire
如果网络层你使用的是 [Alamofire](https://github.com/Alamofire/Alamofire) ,并且你希望把返回的结果转换成 Swift 对象,你可以使用 [AlamofireObjectMapper](https://github.com/tristanhimmelman/AlamofireObjectMapper) 。这是一个使用 ObjectMapper 实现的把返回的 JSON 自动转成 Swift 对象的 Alamofire 的扩展。
# ObjectMapper + Realm
ObjectMapper 可以和 Realm 一起配合使用。使用下面的声明结构就可以使用 ObjectMapper 生成 Realm 对象:
```swift
class Model: Object, Mappable {
dynamic var name = ""
required convenience init?(map: Map) {
self.init()
}
func mapping(map: Map) {
name <- map["name"]
}
}
```
如果你想要序列化相关联的 RealmObject,你可以使用 [ObjectMapper+Realm](https://github.com/jakenberg/ObjectMapper-Realm)。这是一个简单的 Realm 扩展,用于把任意的 JSON 序列化成 Realm 的类(ealm's List class。)
注意:使用 ObjectMappers 的 `toJSON` 函数来生成 JSON 字符串只在 Realm 的写事务中有效(write transaction)。这是因为 ObjectMapper 在解析和生成时在映射函数( `<-` )中使用 `inout` 作为标记( flag )。Realm 会检测到标记并且强制要求 `toJSON` 函数只能在一个写的事务中调用,即使这个对象并没有被修改。
# 待完成
- 改善错误的处理。可能使用 `throws` 来处理。
- 相关类的文档完善
# 安装
### Cocoapods
如果你的项目使用 [CocoaPods 0.36 及以上](http://blog.cocoapods.org/Pod-Authors-Guide-to-CocoaPods-Frameworks/) 的版本,你可以把下面内容添加到在 `Podfile` 中,将 ObjectMapper 添加到你的项目中:
```ruby
pod 'ObjectMapper', '~> 2.2'
```
### Carthage
如果你的项目使用 [Carthage](https://github.com/Carthage/Carthage) ,你可以把下面的内容添加到 `Cartfile` 中,将 ObjectMapper 的依赖到你的项目中:
```
github "Hearst-DD/ObjectMapper" ~> 2.2
```
### Swift Package Manager
如果你的项目使用 [Swift Package Manager](https://swift.org/package-manager/) ,那么你可以把下面内容添加到 `Package.swift` 中的 `dependencies` 数组中,将 ObjectMapper 的依赖到你的项目中:
```swift
.Package(url: "https://github.com/Hearst-DD/ObjectMapper.git", majorVersion: 2, minor: 2),
```
### Submodule
此外,ObjectMapper 也可以作为一个 submodule 添加到项目中:
1. 打开终端,使用 `cd` 命令进入项目文件的根目录下,然后在终端中输入 `git submodule add https://github.com/Hearst-DD/ObjectMapper.git` ,把 ObjectMapper 作为项目的一个 [submodule](http://git-scm.com/docs/git-submodule) 添加进来。
2. 打开 `ObjectMapper` 文件,并将 `ObjectMapper.xcodeproj` 拖进你 app 项目的文件导航中。
3. 在 Xcode 中,文件导航中点击蓝色项目图标进入到 target 配置界面,在侧边栏的 "TARGETS" 下选择主工程对应的target。
4. 确保 `ObjectMapper.framework` 的部署版本( deployment target )和主工程的部署版本保持一致。
5. 在配置界面的顶部选项栏中,打开 "Build Phases" 面板。
6. 展开 "Target Dependencies" 组,并添加 `ObjectMapper.framework` 。
7. 点击面板左上角的 `+` 按钮,选择 "New Copy Files Phase"。将这个阶段重命名为 "Copy Frameworks",设置 "Destination" 为 "Frameworks",最后添加 `ObjectMapper.framework` 。
