私は、複数のView Controllerを持つIpadゲームを構築しました。その最初（ROOT VCで）は2時間からのカウントダウンにタイマーを起動します。 XCODE 8.2.1/Swift 3で実行しています。タイマーでUILabel.textを更新すると、TouchesBegan/TouchesEndedが不具合を引き起こします。
さらにViewController（6番目または7番目）のViewControllerでは、ユーザーが8個のUIImageViewsから4個のUIImageViewsにドラッグアンドドロップするミニゲームがあります。空のスロット）をTouchesBegan/TouchesMoved/TouchesEnded経由で実行します。 （UIImageViewsはInterface Builderによって設定されます）。
（UserInteraction = disabledの）画面上部に、現在のView Controllerがロードされたときに発生するタイマーを介して、1秒おきに現在の時刻（2時間カウントダウン時）に更新されるラベルがあります（showgametimeTimerは以下のコードにあります）。
問題：これはミニゲームを駄目にします（ユーザーが指でドラッグを終了したときに画像が目的の位置に「ロック」しません）。この「グリッチ」はラベルを更新しているタイマーが動作しているときにのみ発生します。
私はタイマーを無効にすれば、すべてうまく動作し、期待どおりです。
何らかの理由で、1秒ごとにタイマーからUILabel.textを更新すると、TouchesBeganやTouchesEndedに影響するものが呼び出されます。
UILabel.textは画面上部にあり、移動するオブジェクトは下部にあります。私はブーリアンロジックを設定しようとしました - つまり、touchesBeganの始めにtimer.invalidateを、TouchesEndedの最後にタイマーを復帰させて、役に立たなくしました。問題は残っています。
これを修正する唯一の方法は、このView Controllerでタイマーを完全に無効にすることです。
私はこのコードを追加していますが、実際に問題を見るのに役立つとは思えません。誰かが同じ問題に遭遇したのか、それとも何かを修正する方法があるのだろうか？初心者のプログラマー。
