在AppDelegate.m對場景進行初始化時，導演類會跳轉到場景→IntroLayer scene
這個場景是在IntroLayer裏新建的類型爲CCScene
+(CCScene *) scene
這個場景會一閃而過，這個文件的最下面有個onEnter的實例方法，會直接跳轉到另一個場景→HelloWorldLayer scene
在HelloWorldLayer初始化時，init
-(id) init
{
// always call "super" init
// Apple recommends to re-assign "self" with the "super's" return value
if( (self=[super initWithColor:(ccc4(255,0,0,150))])) {
......
}
return self;
}
這裏的if( (self=[super initWithColor:(ccc4(255,0,0,150))])) {
......
會設置背景顏色！
