UIKit 示例
- 如果存在，如何检查会话的 状态。《KeychainItem》用于在 Keychain 中获取和设置 appleId（不包括在包装器中）
import UIKit
import AuthenticationServices
import AppleSignInWrapper
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
ApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
if #available(iOS 13.0, *) {
AppleSignInWrapper().checkUserState(userID: KeychainItem.currentUserIdentifier) { (state: ASAuthorizationAppleIDProvider.CredentialState?, error:Error?) in
if let anError: Error = error{
// Here you should call your Login ViewController
} else if let aState: ASAuthorizationAppleIDProvider.CredentialState = state{
switch aState {
case .authorized:
DispatchQueue.main.async {
// Here you should call your backend to create a session
}
case .notFound, .revoked:
DispatchQueue.main.async {
// Here you should call your Login ViewController
}
default:
// Here you should call your Login ViewController
}
} else {
// Here you should call your Login ViewController
}
}
} else {
// Fallback on earlier versions
// Here you should call your Login ViewController without Apple Sign In Button
}
return true
}
- 如何使用包装器实现 Apple Sign In
import UIKit
import AuthenticationServices
import AppleSignInWrapper
@available(iOS 13.0, *)
class ViewController: AppleIDLoginDelegate {
// MARK: - Outlets
@IBOutlet weak var btnAppleSignIn: AppleIDButtonWrapper!
var appleWrapper: AppleSignInWrapper!
override func viewDidLoad() {
super.viewDidLoad()
btnAppleSignIn.addTarget(self,
action: #selector(userTappedSignInWithApple),
for: .touchUpInside)
appleWrapper = AppleSignInWrapper(view: self.view)
appleWrapper.delegate = self
// Do any additional setup after loading the view.
}
@objc func userTappedSignInWithApple() {
appleWrapper.requestSignIn()
}
func appleSignInWrapper(didComplete withError: Error) {
}
func appleSignInWrapper(didComplete withUser: UserInformation) {
// Here you should save your user identifier and backend stuff
}
}
- 如何在使用 Storyboard 中使用 AppleSignInButton
- 在您的 Storyboard 中创建一个 UIButton
- 将 AppleIDButtonWrapper 设置为按钮的自定义类。
- 享受并自定义您的按钮
- 如果您使用约束，请阅读 Apple 指南以避免在约束中的警告，并使按钮正确地出现在您的视图中。
SwiftUI 示例
- 创建一个用于使用 AppleIDButtonWrapper 的 UIViewRepresentable
import SwiftUI
import AppleSignInWrapper
struct AppleSignInButton: UIViewRepresentable {
@Binding var firstName: String
@Binding var lastName: String
@Binding var userIdentifier: String
@Binding var email: String?
typealias UIViewType = AppleIDButtonWrapper
func makeCoordinator() -> AppleSignInCoordinator {
return AppleSignInCoordinator(loginView: self)
}
func makeUIView(context: UIViewRepresentableContext<AppleSignInButton>) -> AppleIDButtonWrapper {
let appleSignInButton = AppleIDButtonWrapper()
appleSignInButton.authButtonType = 1
appleSignInButton.authButtonStyle = 2
appleSignInButton.layer.cornerRadius = 0
appleSignInButton.addTarget(context.coordinator, action: #selector(context.coordinator.userTappedAppleSignIn), for: .touchUpInside)
return appleSignInButton
}
func updateUIView(_ uiView: AppleIDButtonWrapper, context: UIViewRepresentableContext<AppleSignInButton>) {
}
}
- 创建一个 coordinator 来管理包装器的代理方法。
import SwiftUI
import AuthenticationServices
import AppleSignInWrapper
class AppleSignInCoordinator: NSObject {
var appleWrapper: AppleSignInWrapper!
var loginView: AppleSignInButton?
override init() {
super.init()
appleWrapper = AppleSignInWrapper()
appleWrapper.delegate = self
}
init(loginView: AppleSignInButton) {
super.init()
self.loginView = loginView
appleWrapper = AppleSignInWrapper()
appleWrapper.delegate = self
}
@objc func userTappedAppleSignIn() {
appleWrapper.view = UIApplication.shared.windows.last!.rootViewController?.view
appleWrapper.requestSignIn()
}
}
extension AppleSignInCoordinator: AppleIDLoginDelegate {
func appleSignInWrapper(didComplete withError: Error) {
}
func appleSignInWrapper(didComplete withUser: UserInformation, nonce: String?) {
loginView?.email = withUser.email
loginView?.firstName = withUser.firstName
loginView?.lastName = withUser.lastName
loginView?.userIdentifier = withUser.userIdentifier
}
}
- 使用您的 AppleSignInButton
import SwiftUI
struct ContentView: View {
var body: some View {
AppleSignInButton(firstName: .constant(""),
lastName: .constant(""),
userIdentifier: .constant(""),
email: .constant(""))
.frame(width: 200, height: 40, alignment: .center)
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
