Set a reason to show to your users, then authenticate to verify identity.

[[EHFAuthenticator sharedInstance] setReason:@"Authenticate with Touch ID to access secure data"]
[[EHFAuthenticator sharedInstance] authenticateWithSuccess:^(){
    // Success
} andFailure:^(LAError errorCode){
  //Handle LAError codes.  See example project for the different errors that can occur.
}];

EHFAuthenticator.sharedInstance.reason = "Authenticate with Touch ID to access secure data"
EHFAuthenticator.sharedInstance.authenticateWithSuccess({
    // Success
}, failure:{ errorCode in
  //Handle LAError codes.  See example project for the different errors that can occur.
