ボタンのハンドラ追加

追加したボタンをダブクリして、ハンドラ追加してコードをコピペ:


		void AuthenticateMe (UIButton sender) 
		{	 
			var context = new LAContext(); 
			NSError AuthError; 
			var myReason = new NSString("To add a new chore"); 

			if (context.CanEvaluatePolicy(
				LAPolicy.DeviceOwnerAuthenticationWithBiometrics, 
				out AuthError)){ 

				var replyHandler = new LAContextReplyHandler((success, error) => 
					{ 
						this.InvokeOnMainThread(()=>{ 
							if(success){ 
								Console.WriteLine("You logged in!"); 
								PerformSegue("AuthenticationSegue", this); 
							} else{ 
								//Show fallback mechanism here 
							} 
						}); 
					}); 
				context.EvaluatePolicy(
					LAPolicy.DeviceOwnerAuthenticationWithBiometrics, myReason, replyHandler); 
			}; 
		}

		partial void AuthenticateButton_TouchUpInside (UIButton sender)
		{
			this.AuthenticateMe(sender);
		}

ターゲットOS変更

実行

親指だと認証と追ってしまうので、人差し指使ってスクショ取ったために認証エラーになっている。親指だと認証通って、セグエでPushする先のView Controllerに移動します。
