Comment intégrer le flux 'Se connecter avec Apple' dans iOS Objective-C?
Je souhaite intégrer "Se connecter avec Apple" dans mon application iOS. J'ai trouvé de nombreux exemples de code pour cela, mais tous sont en Swift et j'ai besoin d'Objective-C.
Étape 1 :
à titre de référence, j'ai pris les informations d'ici iOS 13 - Connectez-vous avec Apple Tutorial et ici
pour le code complet, vous pouvez télécharger à partir de github-Sign-In-with-Apple
Ajout d'une connexion avec Apple Capacité
Sous le fichier de projet Xcode, il y a signature et capacités disponibles. Appuyez sur + et ajoutez la fonction "Se connecter avec Apple" .
Étape 2
ajoutez le framework AuthenticationServices dans target -> general -> frameworks et #import<AuthenticationServices/AuthenticationServices.h> dans votre viewcontroller
Étape 3
ici, j'ai créé l'objet setCurrentIdentifier pour enregistrer l'utilisateur actuel et j'ai créé la vue de texte pour afficher la sortie à l'écran.
affecter le délégué <ASAuthorizationControllerDelegate,ASAuthorizationControllerPresentationContextProviding> dans votre interface
extern NSString* const setCurrentIdentifier;
@interface ViewController : UIViewController<ASAuthorizationControllerDelegate,ASAuthorizationControllerPresentationContextProviding>
@property (nonatomic, strong) UITextView *appleIDLoginInfoTextView;
NSString* const setCurrentIdentifier = @"setCurrentIdentifier";
Étape 4
sur l'interface utilisateur de votre contrôleur charge la configuration de votre objet et observez AppleSignInState comme ci-dessous
@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];
}
