[self Language]与[self schedule:@selector(Language)];的区别

代码是如下:

-(void)Language{

    CCScene *sc=[CCScene node];

    GameMenu *Points=[GameMenu node];

    [sc addChild:Points z:1 tag:1];

    [[CCDirector sharedDirector] replaceScene:[CCTransitionCrossFade  transitionWithDuration:1 scene:sc]];

    [self unschedule:@selector(Language)];

}

- (id)init {

    self = [super init];

    if (self) {

        int yuyanset = [[NSUserDefaults standardUserDefaults] integerForKey:@"yuyanset"];

        if (yuyanset==0) { 

            CCMenuItemFont *Cn=[CCMenuItemFont itemFromString:@"简体中文" target:self selector:@selector(Cn:)];

            CCMenuItemFont *En=[CCMenuItemFont itemFromString:@"English" target:self selector:@selector(En:)];

            CCMenu *Language=[CCMenu menuWithItems:Cn,En,nil];

            [Language alignItemsVertically];  

            [Language alignItemsVerticallyWithPadding:25];

            [self addChild:Language];

            [[NSUserDefaults standardUserDefaults] setInteger:1 forKey:@"yuyanset"];  

        }else{

                [self schedule:@selector(Language)];

        }    }

    return self;

}

-(void)Cn:(id)sender{

    [[NSUserDefaults standardUserDefaults] setInteger:0 forKey:@"yuyan"];  

    [self Language]; 

}

-(void)En:(id)sender{

    [[NSUserDefaults standardUserDefaults] setInteger:1 forKey:@"yuyan"];  

    [self Language];

}

- (void)dealloc {

      [super dealloc];

}

[self  Language]与[self schedule:@selector(Language)];的区别

[self  Language]是OBJC的调用方法!

[self schedule:@selector(Language)]; 是cocos2d选择器(selector)或者用@selector(...)关键词的方式来预定

更新方法;


如果上面代码用[self  Language]你会看到一个黑屏!没有其他的效果!

这样你只有使用[self schedule:@selector(Language)]; 才能进行跳转!才能达到预期的效果!
