マルチタッチは、渡されたパラメータに基づいて決定されます.パラメータがコントロール要素である場合は、performMultipointerGestureメソッドを呼び出し、パラメータが一連の点である場合は反射を呼び出します.では具体的に2つの方法の詳細を見てみましょう.

try {
if (API_18) {
// The compile-time SDK expects the wrong arguments, but the runtime

// `return el.performMultiPointerGesture(touches);`
// Instead we need to use Reflection to do it all at runtime.

Uiobjectで直接呼び出せるperformMultipointerGestureメソッドがありますが、なぜ反射を使うのでしょうか.上記の方法の注釈は、コンパイル時にsdkはパラメータが間違っていると判断しますが、実行時には正しいと判断しますので、実行時に呼び出すだけで正確性が保証されます.反射呼び出しは実行時の環境なので、反射呼び出しperformMultipointerGestureを使用します.
ポイントグループ
api 18以上のバージョンでは、ポインティンググループのメソッドが呼び出されるので、sdkのバージョンを先に判断します.apiが18以上の場合はInteractionControllerを呼び出す.performMultipointerGestureの方法で実行
