アクション後に次の処理を実行

移動後に画像切り替えの例

        CCMoveBy* moveBy = [CCMoveBy actionWithDuration:1.0 position:ccp(100, 100)];
        CCCallBlock* block = [CCCallBlock actionWithBlock:^{
            //アクション後に画像切り替え
            CCTexture2D *texture = [[CCTextureCache sharedTextureCache] addImage:@"image.png"];
            [sprite setTexture:texture];
            [sprite setTextureRect:CGRectMake(0, 0, texture.contentSize.width, texture.contentSize.height)];
        }];
        CCSequence* seq = [CCSequence actions:moveBy, block, nil];
        [sprite runAction:seq];
