我想在我的iOS应用程序中集成“使用Apple登录”。我已经找到了很多与此相关的代码示例,但所有示例均在Swift中,我需要使用Objective-C。
yimao5788 回答:如何在iOS Objective-C中集成“用苹果登录”流程?
步骤-1:
出于参考目的,我从这里iOS 13 — Sign In with Apple Tutorial和here那里获得了信息
有关完整代码,您可以从github-Sign-In-with-Apple下载
添加具有Apple功能的登录
在Xcode项目文件下,提供了“签名和功能”。按下 + 并添加“使用Apple登录” 功能。
步骤-2
在目标->常规->框架中添加 AuthenticationServices框架,并在您的视图控制器中添加#import<AuthenticationServices/AuthenticationServices.h>
第3步
在这里,我创建了setCurrentIdentifier对象来保存当前用户,并创建了textview以便在屏幕上显示Output。
在界面中分配委托人<ASAuthorizationControllerDelegate,ASAuthorizationControllerPresentationContextProviding>
extern NSString* const setCurrentIdentifier;
@interface ViewController : UIViewController<ASAuthorizationControllerDelegate,ASAuthorizationControllerPresentationContextProviding>
@property (nonatomic,strong) UITextView *appleIDLoginInfoTextView;
NSString* const setCurrentIdentifier = @"setCurrentIdentifier";
第4步
在控制器UI上加载设置对象并观察如下的AppleSignInState
@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];
}
}
