带有 Alamofire 和 ObjectMapper 的 Swift 4.0 没有这样的模块'ObjectMapper'

Question

嗨，我是IOS开发的新手。我正在创建一个小应用程序。我正在尝试导入对象映射器，但它没有找到模块。我已经做了 pod 安装。我的 pod 文件看起来像：

target 'Sample' do
# Comment the next line if you're not using Swift and don't want to use dynamic frameworks
use_frameworks!
# Pods for Sample
pod 'Alamofire', '~> 4.5.0'
pod 'AlamofireObjectMapper', '~> 5.0'
pod 'AlamofireImage', '~> 3.3'
pod 'PKHUD', '~> 5.0'
pod 'ObjectMapper', '~> 3.0.0'

结束

我使用的是 swift 版本 4.0.2，Xcode 版本是 9.1。有什么东西不见了吗？需要一些帮助。

Answer 1

最新版本的ObjectMapperpod 'ObjectMapper', '~> 3.1'，一件事是干净的，并构建您的项目并确保您正在处理YourProjectName.xcworkspace

Answer 2

尝试使用 3.4 版 . 它对我有用。

pod 'ObjectMapper', '~> 3.4'

1) Model Class One--------------
-----------------------------------------
-----------------------------------------
import Foundation
import ObjectMapper
class MainData : NSObject, Mappable {
var page : Int?
var per_page : Int?
var total : Int?
var total_pages : Int?
var data : [Data]?
override init() {
}
required init?(map: Map) {
}
func mapping(map: Map) {
page <- map["page"]
per_page <- map["per_page"]
total <- map["total"]
total_pages <- map["total_pages"]
data <- map["data"]
}
}
2) Model Class Two--------------
-----------------------------------------
-----------------------------------------
import Foundation
import ObjectMapper
class Data : NSObject, Mappable {
var id : Int?
var name : String?
var year : Int?
var color : String?
var pantone_value : String?
override init() {
}
required init?(map: Map) {
}
func mapping(map: Map) {
id <- map["id"]
name <- map["name"]
year <- map["year"]
color <- map["color"]
pantone_value <- map["pantone_value"]
}
}
3) ViewController--------------
