向图层添加图层不起作用

我一直试图让一个图层进入我的场景。我的场景叫做“生存”。我的图层叫做“SSpriteLayer”。场景初始化,但图层没有。

SURVIVAL.H:

#import <Foundation/Foundation.h>
#import "cocos2d.h"
#import "SSpriteLayer.h"

@interface Survival : CCLayer {}
@end

SURVIVAL.M:

@implementation Survival

+(CCScene *) scene
{
   // 'scene' is an autorelease object.
   CCScene *scene = [CCScene node];

   // 'layer' is an autorelease object.
   Survival *layer = [Survival node];
   SSpriteLayer *spriteLayer = [SSpriteLayer node];

   // add layer as a child to scene
   [scene addChild: layer];
   [scene addChild: spriteLayer];

   // return the scene
   return scene;
}

-(id) init
{
   if( (self=[super init]))        
       NSLog(@"SCENE HAS INIT");

   return self;
}

@end

SSPRITELAYER.H:

#import <Foundation/Foundation.h>
#import "cocos2d.h"

@interface SSpriteLayer : CCLayer {

}

@end

SSPRITELAYER.M:

#import "SSpriteLayer.h"


@implementation SSpriteLayer

-(id) init
{
   if( (self=[super init]))         
       NSLog(@"SPRITELAYER HAS INIT");  

   return self;
}


@end

我不明白为什么我的图层没有初始化,为什么我没有在调试区域收到“SPRITELAYER HAS INIT”消息。

  // add layer as a child to scene

确保您致电

[Survival scene];

[Survival node];
