如何用Java在MacOS上实现Touch ID认证

#import <LocalAuthentication/LocalAuthentication.h>

@implementation TouchIDHandler

+ (BOOL)isTouchIDAvailable {
    LAContext *context = [[LAContext alloc] init];
    NSError *error = nil;
    return [context canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&error];
}

+ (void)authenticateUserWithCompletion:(void (^)(BOOL success, NSError *error))completion {
    LAContext *context = [[LAContext alloc] init];
    [context evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics
            localizedReason:@"Authenticate to access your account"
                      reply:^(BOOL success, NSError *error) {
                          completion(success, error);
                      }];
}

@end

    static {
        System.loadLibrary("TouchIDHandler");
    }

    public interface TouchIDCallback {
        void onSuccess();
        void onFailure(int errorCode);
    }
}
