swift sign in with Apple-苹果ID登录

1.简介

最新苹果系统13.0添加了苹果账号登录的模块，包括指纹和face id的登录；并且除去一些特殊的应用，项目中如果引入了三方登录（例如微信、QQ等），苹果账号登录是必选项。最近项目中需要进行三方登录的添加，就熟悉了一下苹果账号登录，记录一下。

3.集成步骤

3.1证书配置

证书配置完后，下载安装更新本地证书。

3.2项目配置

项目配置完后，添加苹果账号工具类，书写代码。

4.代码

苹果账号登录系统模块为：import AuthenticationServices；我用的是单例工具类，登录触发按钮是全部自定义的，以下是代码。

4.1工具类代码

import Foundation
import AuthenticationServices

typealias ZBYAppleLoginToolSuccessClosures = (_ user: String, _ token: String) -> Void
typealias ZBYAppleLoginToolFailureClosures = (_ error: BaseError) -> Void

@available(iOS 13, *)
class ZBYAppleLoginTool: NSObject {
    static let instence = ZBYAppleLoginTool.init()
    
    private override init() {
        
    }
    
    override func copy() -> Any {
        return ZBYAppleLoginTool.instence // self
    }
    
    override func mutableCopy() -> Any {
        return ZBYAppleLoginTool.instence // self
    }
    
    // Optional
    public func reset() {
        // Reset all properties to default value
    }
    
    private weak var parentController: UIViewController?
    
    private var successCompelecte: ZBYAppleLoginToolSuccessClosures?
    private var failureCompelecte: ZBYAppleLoginToolFailureClosures?
    
    public func isPast() -> Void {
        let provider = ASAuthorizationAppleIDProvider.init()
        provider.getCredentialState(forUserID: "") { (status, error) in
            switch status {
            case .revoked: do { // 已撤销
                
                }
            case .authorized: do {  // 已授权
                
                }
            case .notFound: do {    // 未发现
                
                }
            case .transferred: do { // 已转移
                
                }
            @unknown default:
                break
            }
        }
    }
    
    public func show(success: ZBYAppleLoginToolSuccessClosures? = nil, failure: ZBYAppleLoginToolFailureClosures? = nil) {
        self.successCompelecte = success
        self.failureCompelecte = failure
        let provider = ASAuthorizationAppleIDProvider.init()
        let request = provider.createRequest()
        let controller = ASAuthorizationController.init(authorizationRequests: [request])
        controller.delegate = self
        controller.presentationContextProvider = self
        controller.performRequests()
    }
}

@available(iOS 13, *)
extension ZBYAppleLoginTool: ASAuthorizationControllerPresentationContextProviding {
    func presentationAnchor(for controller: ASAuthorizationController) -> ASPresentationAnchor {
        return kKeyWindow
    }
}

@available(iOS 13, *)
extension ZBYAppleLoginTool: ASAuthorizationControllerDelegate {
    func authorizationController(controller: ASAuthorizationController, didCompleteWithError error: Error) {
        var baseError = BaseError.init()
        baseError.code = Int.init(error._code)
        switch baseError.code {
        case ASAuthorizationError.Code.canceled.rawValue:
            baseError.description = "取消授权"
        case ASAuthorizationError.Code.failed.rawValue:
            baseError.description = "授权请求失败"
        case ASAuthorizationError.Code.invalidResponse.rawValue:
            baseError.description = "授权请求响应无效"
        case ASAuthorizationError.Code.notHandled.rawValue:
            baseError.description = "未能处理授权请求"
        default:
            baseError.description = "授权失败"
        }
        self.failureCompelecte?(baseError)
    }
    
    func authorizationController(controller: ASAuthorizationController, didCompleteWithAuthorization authorization: ASAuthorization) {
        if authorization.credential is ASAuthorizationAppleIDCredential {   // 登录
            let credential = authorization.credential as! ASAuthorizationAppleIDCredential
            let user = credential.user
//            let fullName = credential.fullName
//            let email = credential.email
            guard let identityToken = credential.identityToken else {
                self.failureCompelecte?(BaseError.init(0, "identityToken为空"))
                return
            }
            guard let token = String.init(data: identityToken, encoding: .utf8) else {
                self.failureCompelecte?(BaseError.init(0, "identityToken为空"))
                return
            }
            self.successCompelecte?(user, token)
        }
        else if authorization.credential is ASPasswordCredential {  // 使用现有的iCloud密钥链凭证登录。
//            let credential = authorization.credential as! ASPasswordCredential
//            let user = credential.user
//            let password = credential.password
            let baseError = BaseError.init(0, "授权失败")
            self.failureCompelecte?(baseError)
        }
        else {
            let baseError = BaseError.init(0, "授权失败")
            self.failureCompelecte?(baseError)
        }
    }
}

4.2调用代码

if type == .apple {
            if #available(iOS 13, *) {
                ZBYAppleLoginTool.instence.show(success: { (user, token) in
                    NSLog(user)
                }) { (error) in
                    MBProgressTool.show(to: self.view, text: error.description)
                }
            }
        }
        else {
            
        }
