UISliderがNSRangeExceptionをスローする

各スライダの最小値、最大値、現在値をストーリーボードのデフォルト値に設定しても、スライダを動かすと値が何とか2に移動したというエラーがスローされます。：UISliderがNSRangeExceptionをスローする

のTaスタックトレースの最初の数フレームを見てください。あなたのvertical(_:)方法は、コンポーネントで選択された行のためのピッカービューを要求し、ピッカービューからオブジェクトを取得しようとすることを我々は見

：私は、スクロールを避けるために、画像やアドレスの列を切り出すますアレイ。

ピッカービューにはおそらくコンポーネントの配列があり、配列からコンポーネント2を取得しようとしています。なぜなら（）vertical(_:)で2つの異なる場所であなたはそれを聞いて

2.コンポーネントに関する私の推測では、あなたのピッカービューはインデックスのみ0と1

おっとと、2つのコンポーネントがあります！私はコンポーネントに0から始まる番号が付いていることを完全に忘れていました。 –
