【问题描述】：

我在 ios 设备上使用 Cocos2D 3.0。

在我的 HUD 类中，我有 4 个按钮（SneakyInput 库），左右 ButtonA 和 ButtonB，一切正常，但是当我移动手指（不抬起屏幕）时，按钮被按住。

现在发生的情况是，当我按下一个按钮并移动我的手指按钮时，直到您抬起手指为止。

我想要：

当我触摸 buttonA 并将手指移到 buttonB 时，buttonB 按钮起作用。

我见过很多游戏都可以毫无问题地实现这一点，但现在我做不到。 >_<.>

我的游戏运行良好，我只是想实现这个选项以使其更易于管理。

下面是 Sneaky 按钮的实现代码：

-(void) loadControls 
//Screen Size
CGSize winSize = [[CCDirector sharedDirector] viewSize];

//Load Spritesheets
CCSprite *botonA = [CCSprite spriteWithImageNamed:@"botona.png"];
CCSprite *left = [CCSprite spriteWithImageNamed:@"izquierda.png"];

//Boton A
SneakyButtonSkinnedBase *baseBotonA = [[SneakyButtonSkinnedBase alloc] init];
baseBotonA.position = ccp(winSize.width - botonA.contentSize.width ,botonA.contentSize.height);
baseBotonA.defaultSprite = [CCSprite spriteWithImageNamed:@"botona.png"];
baseBotonA.activatedSprite = [CCSprite spriteWithImageNamed:@"botona.png"];
baseBotonA.pressSprite = [CCSprite spriteWithImageNamed:@"botonaselected.png"];
baseBotonA.button = [[SneakyButton alloc] initWithRect:CGRectMake(0, 0, 100, 100)]; //Ajustar
buttonA = baseBotonA.button;
buttonA.isToggleable = YES;

//Boton B
SneakyButtonSkinnedBase *baseBotonB = [[SneakyButtonSkinnedBase alloc] init];
baseBotonB.position = ccp(winSize.width - (botonA.contentSize.width * 2) - (botonA.contentSize.width / 2) ,botonA.contentSize.height);
baseBotonB.defaultSprite = [CCSprite spriteWithImageNamed:@"botonb.png"];
baseBotonB.activatedSprite = [CCSprite spriteWithImageNamed:@"botonb.png"]; 
baseBotonB.pressSprite = [CCSprite spriteWithImageNamed:@"botonbselected.png"]; 
baseBotonB.button = [[SneakyButton alloc] initWithRect:CGRectMake(0, 0, 100, 100)]; 
buttonB = baseBotonB.button;
buttonB.isToggleable = YES;

//Boton Left
SneakyButtonSkinnedBase *baseBotonLeft = [[SneakyButtonSkinnedBase alloc] init];
baseBotonLeft.position = ccp(left.contentSize.width,left.contentSize.height);
baseBotonLeft.defaultSprite = [CCSprite spriteWithImageNamed:@"izquierda.png"];
baseBotonLeft.activatedSprite = [CCSprite spriteWithImageNamed:@"izquierda.png"]; 
baseBotonLeft.pressSprite = [CCSprite spriteWithImageNamed:@"izquierdaselected.png"]; 
baseBotonLeft.button = [[SneakyButton alloc] initWithRect:CGRectMake(0, 0, 100, 100)]; 
buttonLeft = baseBotonLeft.button;
buttonLeft.isToggleable = YES;

//Boton Right
SneakyButtonSkinnedBase *baseBotonRight = [[SneakyButtonSkinnedBase alloc] init];
baseBotonRight.position = ccp((left.contentSize.width * 2) + (left.contentSize.width / 2),left.contentSize.height);
baseBotonRight.defaultSprite = [CCSprite spriteWithImageNamed:@"derecha.png"];
baseBotonRight.activatedSprite = [CCSprite spriteWithImageNamed:@"derecha.png"]; 
baseBotonRight.pressSprite = [CCSprite spriteWithImageNamed:@"derechaselected.png"]; 
baseBotonRight.button = [[SneakyButton alloc] initWithRect:CGRectMake(0, 0, 100, 100)]; 
buttonRight = baseBotonRight.button;
buttonRight.isToggleable = YES;

[layoutBox addChild:baseBotonA];
[layoutBox addChild:baseBotonB];
[layoutBox addChild:baseBotonLeft];
[layoutBox addChild:baseBotonRight];

[self addChild:layoutBox];

对不起，我的英语不好，我在没有翻译的情况下尝试:(

【参考方案1】：

将按钮上的claimsUserInteraction 属性设置为NO。

来自CCResponder 的 Cocos2D 文档：

/** 
 *  Locks the touch to the node if touch moved outside
 *  If a node claims user interaction, the touch will continue to be sent to the node, no matter where the touch is moved
 *  If the node does not claim user interaction, a touch will be cancelled, if moved outside the nodes detection area
 *  If the node does not claim user interaction, and a touch is moved from outside the nodes detection area, to inside, a touchBegan will be generated.
 */
@property (nonatomic, assign) BOOL claimsUserInteraction;
