Iphone cocos2d+；加速度计问题

我完成了我的游戏（cocos2d），但当我制作一个存档（从xcode产品->存档），然后点击共享（获取game.api），然后将它放在itunes中，并同步到我的iphone加速计上，它似乎不起作用。我在5台设备上测试了游戏，但它不起作用，飞船总是在固定的位置，它没有移动，但是，如果我单击build并从xcode开始，它将在所有开发人员设备上正常工作，我将使用以下代码：

在init内部

- (id)init
{
    if ((self = [super init]))
    {
    self.isAccelerometerEnabled = YES;
    [self scheduleUpdate];
}

加速计搬运器：

- (void)accelerometer:(UIAccelerometer *)accelerometer 
    didAccelerate:(UIAcceleration *)acceleration {

#define kFilteringFactor 0.1
UIAccelerationValue rollingX, rollingY, rollingZ;

rollingX = (acceleration.x * kFilteringFactor) + 
    (rollingX * (1.0 - kFilteringFactor));    
rollingY = (acceleration.y * kFilteringFactor) + 
    (rollingY * (1.0 - kFilteringFactor));    
rollingZ = (acceleration.z * kFilteringFactor) + 
    (rollingZ * (1.0 - kFilteringFactor));

float accelX = acceleration.x - rollingX;

CGSize winSize = [CCDirector sharedDirector].winSize;

#define kRestAccelX 0.6
#define kShipMaxPointsPerSec (winSize.height*0.5)
#define kMaxDiffX 0.2

float accelDiffX = kRestAccelX - ABS(accelX);
float accelFractionX = accelDiffX / kMaxDiffX;
float pointsPerSecX = kShipMaxPointsPerSec * accelFractionX;

_shipPointsPerSecY = pointsPerSecX;

}

船位：

- (void)updateShipPos:(ccTime)dt {

    CGSize winSize = [CCDirector sharedDirector].winSize;

    float maxY = winSize.height - _ship.contentSize.height/2;
    float minY = _ship.contentSize.height/2;
    float newY ;
    (isYAxisInverted) ? newY = _ship.position.y + (-_shipPointsPerSecY * dt) : newY = _ship.position.y + (_shipPointsPerSecY * dt);
    newY = MIN(MAX(newY, minY), maxY);
    _ship.position = ccp(_ship.position.x, newY);

}

在更新中：

- (void)update:(ccTime)dt {
...
    [self updateShipPos:dt];
...}

---

解决方案是替换：

UIAccelerationValue rollingX

借

UIAccelerationValue rollingX=0，rollingY=0，rollingZ=0
