RxSwift,Kingfisher,Moya,HandyJSON的结合:APP启动时增加了网络上下载的图片
在主要的MainViewController.swift中：
import UIKit
import Kingfisher
import Moya
import RxSwift
class MainViewController: UITabBarController {
let provider = RxMoyaProvider<ApiManager>()
let launchView = UIImageView()
let dispose = DisposeBag()
override func viewDidLoad() {
super.viewDidLoad()
setLaunchView()
}
func setLaunchView() {
launchView.frame = CGRect.init(x: 0, y: 0, width: screenW, height: screenH)
launchView.alpha = 0.99
launchView.backgroundColor = UIColor.black
view.addSubview(launchView)
provider
.request(.getLaunchImg)
.mapModel(LaunchModel.self)
.subscribe(onNext: { (model) in
if let imgModel = model.creatives?.first {
self.launchView.kf.setImage(with: URL.init(string: imgModel.url!), placeholder: nil, options: nil, progressBlock: nil, completionHandler: { (_, _, _, _) in
UIView.animate(withDuration: 1.5, animations: {
self.launchView.alpha = 1
}) { (_) in
UIView.animate(withDuration: 0.3, animations: {
self.launchView.alpha = 0
}, completion: { (_) in
self.launchView.removeFromSuperview()
})
}
})
}
})
.addDisposableTo(dispose)
}
}
在ApiManager.swift中：
import Foundation
import Moya
enum ApiManager {
case getLaunchImg
case getNewsList
case getMoreNews(String)
case getThemeList
case getThemeDesc(Int)
case getNewsDesc(Int)
}
extension ApiManager: TargetType {
/// The target's base `URL`.
var baseURL: URL {
return URL.init(string: "http://news-at.zhihu.com/api/")!
}
/// The path to be appended to `baseURL` to form the full `URL`.
var path: String {
switch self {
case .getLaunchImg:
return "7/prefetch-launch-images/750*1142"
case .getNewsList:
return "4/news/latest"
case .getMoreNews(let date):
return "4/news/before/" + date
case .getThemeList:
return "4/themes"
case .getThemeDesc(let id):
return "4/theme/\(id)"
case .getNewsDesc(let id):
return "4/news/\(id)"
}
}
/// The HTTP method used in the request.
var method: Moya.Method {
return .get
}
/// The parameters to be incoded in the request.
var parameters: [String: Any]? {
return nil
}
/// The method used for parameter encoding.
var parameterEncoding: ParameterEncoding {
return URLEncoding.default
}
/// Provides stub data for use in testing.
var sampleData: Data {
return "".data(using: String.Encoding.utf8)!
}
/// The type of HTTP task to be performed.
var task: Task {
return .request
}
/// Whether or not to perform Alamofire validation. Defaults to `false`.
var validate: Bool {
return false
}
}
在LaunchModel.swift中
import Foundation
import HandyJSON
struct LaunchModel: HandyJSON {
var creatives: [LaunchModelImg]?
}
struct LaunchModelImg: HandyJSON {
var url: String?
var text: String?
var start_time : Int?
var impression_tracks: [String]?
}
在ToModelExtension.swift中：
import Foundation
import RxSwift
import Moya
import HandyJSON
extension ObservableType where E == Response {
public func mapModel
return flatMap { response -> Observable<T> in
return Observable.just(response.mapModel(T.self))
}
}
}
extension Response {
func mapModel
let jsonString = String.init(data: data, encoding: .utf8)
return JSONDeserializer<T>.deserializeFrom(json: jsonString)!
}
