IOSアプリに「Appleでサインイン」を統合したい。私はこれについて多くのコード例を見つけましたが、すべてSwiftにあり、Objective-Cが必要です。
ステップ1 :
参考のために、ここから情報を取得しました iOS 13 — Appleチュートリアル および ここ でサインインします
完全なコードについては、 github-Sign-In-with-Apple からダウンロードできます。
Apple Capabilityでサインインを追加する
Xcodeプロジェクトファイルの下に、利用可能な署名と機能があります。 +を押して、「Appleでサインイン」機能を追加します。
ステップ2
ターゲットにAuthenticationServicesフレームワークを追加します->一般->フレームワークと#import<AuthenticationServices/AuthenticationServices.h>
ビューコントローラ内
ステップ-3
ここでは、現在のユーザーを保存するためのsetCurrentIdentifierオブジェクトを作成し、画面に出力を表示するためのテキストビューを作成しました。
デリゲートを割り当てる<ASAuthorizationControllerDelegate,ASAuthorizationControllerPresentationContextProviding>
インターフェース内
extern NSString* const setCurrentIdentifier;
@interface ViewController : UIViewController<ASAuthorizationControllerDelegate,ASAuthorizationControllerPresentationContextProviding>
@property (nonatomic, strong) UITextView *appleIDLoginInfoTextView;
NSString* const setCurrentIdentifier = @"setCurrentIdentifier";
ステップ-4
コントローラーUIで、オブジェクトをロードしてセットアップし、以下のようにAppleSignInStateを観察します
@synthesize appleIDLoginInfoTextView;
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
if (@available(iOS 13.0, *)) {
[self observeAppleSignInState];
[self setupUI];
}
}
- (void)observeAppleSignInState {
if (@available(iOS 13.0, *)) {
NSNotificationCenter *center = [NSNotificationCenter defaultCenter];
[center addObserver:self selector:@selector(handleSignInWithAppleStateChanged:) name:ASAuthorizationAppleIDProviderCredentialRevokedNotification object:nil];
}
}
- (void)handleSignInWithAppleStateChanged:(id)noti {
NSLog(@"%s", __FUNCTION__);
NSLog(@"%@", noti);
}
- (void)setupUI {
// Sign In With Apple
appleIDLoginInfoTextView = [[UITextView alloc] initWithFrame:CGRectMake(.0, 40.0, CGRectGetWidth(self.view.frame), CGRectGetHeight(self.view.frame) * 0.4) textContainer:nil];
appleIDLoginInfoTextView.font = [UIFont systemFontOfSize:32.0];
[self.view addSubview:appleIDLoginInfoTextView];
if (@available(iOS 13.0, *)) {
// Sign In With Apple Button
ASAuthorizationAppleIDButton *appleIDButton = [ASAuthorizationAppleIDButton new];
appleIDButton.frame = CGRectMake(.0, .0, CGRectGetWidth(self.view.frame) - 40.0, 100.0);
CGPoint Origin = CGPointMake(20.0, CGRectGetMidY(self.view.frame));
CGRect frame = appleIDButton.frame;
frame.Origin = Origin;
appleIDButton.frame = frame;
appleIDButton.cornerRadius = CGRectGetHeight(appleIDButton.frame) * 0.25;
[self.view addSubview:appleIDButton];
[appleIDButton addTarget:self action:@selector(handleAuthrization:) forControlEvents:UIControlEventTouchUpInside];
}
NSMutableString *mStr = [NSMutableString string];
[mStr appendString:@"Sign In With Apple \n"];
appleIDLoginInfoTextView.text = [mStr copy];
}
- (void)handleAuthrization:(UIButton *)sender {
if (@available(iOS 13.0, *)) {
// A mechanism for generating requests to authenticate users based on their Apple ID.
ASAuthorizationAppleIDProvider *appleIDProvider = [ASAuthorizationAppleIDProvider new];
// Creates a new Apple ID authorization request.
ASAuthorizationAppleIDRequest *request = appleIDProvider.createRequest;
// The contact information to be requested from the user during authentication.
request.requestedScopes = @[ASAuthorizationScopeFullName, ASAuthorizationScopeEmail];
// A controller that manages authorization requests created by a provider.
ASAuthorizationController *controller = [[ASAuthorizationController alloc] initWithAuthorizationRequests:@[request]];
// A delegate that the authorization controller informs about the success or failure of an authorization attempt.
controller.delegate = self;
// A delegate that provides a display context in which the system can present an authorization interface to the user.
controller.presentationContextProvider = self;
// starts the authorization flows named during controller initialization.
[controller performRequests];
}
