私は自分のシーンにあるSpritNodesを持っています。私がそれをタッチするとメソッドが呼び出されます。自分のノードでisUserInteractionEnabled
がtrueに設定されていますが、ノードに触れるとtouchesBegan
が呼び出されません。 (注:私はスウィフト3.0を使用しています)touchesはSprit Nodeで呼び出されていません
コード:

シーンの他の場所をタップするとtouchesBeganが呼び出されますか? –
はいそれは – ZachtheBoB
と呼ばれます。email.isUserInteractionEnabled = falseにするとうまくいくはずです。ノードがタッチイベントを受け取り、シーンにそれを通さないことを真に設定します。 –
