Init()とonEnter()の2つの方法はいずれもCCNodeの方法である.違いは次のとおりです.
 
1.呼び出される順序は、init()を先に、onEnter()を後にします.
 
2.init()はクラスの初期化時に一度だけ呼び出されます.
 
3.onEnterは、このクラスがシーンにロードされたときに呼び出され、複数回発生する可能性があります.
 
4.CCLayer* cclayer = new MyLayer();
この場合、onEnterのみがトリガーされます.
 
5.CCLayer* cclayer = MyLayer::create();
この場合、init()メソッドもonEnter()メソッドもトリガされます.
