Question

我使用具有分层结构的cocos2D创建了一个应用程序。

我在子层中的glView上使用了UIButton。

当我回到父图层时，按钮仍然在它的位置。

我想终止它。

我该怎么做？

这是代码。

MainHallLayer.m

- (id)init
{
    self = [super init];

    if (self != nil)
    {
        CCMenu *menuLists = [CCMenu menuWithItems: nil];
        menuLists.position = ccp(screenSize.width/2, screenSize.height/2);
        [self addChild:menuLists z:10];

        NSString *fontName = [NSString stringWithFormat:@"Chalkboard SE"];
        CGFloat fontSize = 28;

        {
            CCLabelTTF *label = [CCLabelTTF labelWithString:@"Touch Field : Getting 
                            touches coordinates" fontName:fontName fontSize:fontSize];
            [label setColor:ccc3(0.0, 0.0, 0.0)];
            label.anchorPoint = ccp(0, 0.5f);
            CCMenuItem *menuItem = [CCMenuItemLabel itemWithLabel:label block:^(id 
                                                                            sender)
            {
                CCScene *scene = [TouchField1Layer node];
                [ReturningNode returnToNodeWithParent:scene];
                [[CCDirector sharedDirector] replaceScene:scene];
            }];
            [menuLists addChild:menuItem];
        }
    }
    return self;
}

ReturnToNode.m - （id）initWithParentNode：（CCNode *）parentNode { self = [super init];

    if (self != nil) 
    {
        CGSize screenSize = [[CCDirector sharedDirector]winSize];

        CCLabelTTF *label = [CCLabelTTF labelWithString:@"  <= Return" 
                                               fontName:@"Gill Sans" 
                                               fontSize:30.0f];
        label.color = ccMAGENTA;

        id tint_1 = [CCTintTo actionWithDuration:0.333f red:1.0 green:.0f blue:.0f];
        id tint_2 = [CCTintTo actionWithDuration:0.333f red:.5f green:.5f blue:.0f];
        id tint_3 = [CCTintTo actionWithDuration:0.333f red:.0f green:1.0 blue:.0f];
        id tint_4 = [CCTintTo actionWithDuration:0.333f red:.0f green:.5f blue:.5f];
        id tint_5 = [CCTintTo actionWithDuration:0.333f red:.0f green:.0f blue:1.0];
        id tint_6 = [CCTintTo actionWithDuration:0.333f red:.5f green:.0f blue:.5f];

        id sequence = [CCSequence actions:tint_1,tint_2,tint_3,tint_4,tint_5,tint_6, nil];
        id repeatAction = [CCRepeatForever actionWithAction:sequence];
        [label runAction:repeatAction];

        CCLayerColor *labelBackground = [CCLayerColor layerWithColor:ccc4(0.0, 0.0, 70, 40) width:label.contentSize.width + 20 height:label.contentSize.height + 20];

        [label addChild:labelBackground z:-1];

        CCMenuItem *menuItem = [CCMenuItemLabel itemWithLabel:label block:^(id sender)
        {
            [self removeFromParentAndCleanup:YES];
            [[CCDirector sharedDirector] replaceScene:[TouchControllerLayer scene]];
        }];

        CCMenu *menu = [CCMenu menuWithItems:menuItem, nil];
        [menu alignItemsVertically];
        menu.position = CGPointMake(label.contentSize.width/2 , screenSize.height - 20);
        [self addChild:menu];

        [parentNode addChild:self z:1000];
    }
    return self;
}

+ (id)returnToNodeWithParent:(CCNode *)parentNode
{
    return [[[self alloc] initWithParentNode:parentNode] autorelease];
}

TouchField1Layer.m - （id）init { self = [super init];

    if (self != nil) 
    {
        BackgroundLayer *background = [BackgroundLayer node];
        TouchField3Layer *layer = [TouchField3Layer node];

        [self addChild:background z:3];
        [self addChild:layer z:2];

        [self preparingTools];
    }
    return self;
}

- (void)preparingTools
{
    UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    button.frame = CGRectMake(0, 0, 100, 40);

    UIView *glView = [CCDirector sharedDirector].openGLView;
    glView.tag = TAG_GLVIEW;
    [glView addSubview:button];
}

欢迎任何建议，帮助。永远谢谢。祝福你。

如果添加UIKit视图，则必须在适当的时间点手动删除它们。 Cocos2D不管理UIKit视图的生命周期，只管理从CCNode派生的类。

例如，在更改场景时，您必须从-(void) dealloc或-(void) cleanup中的glView中删除UIButton。

在cocos2d中终止glView
