Question

我完成了我的游戏（cocos2d），但是当我进行存档（来自xcode product-＆gt; Archive）然后点击共享（获取game.api）然后将其放入iTunes中并同步到我的iphone加速计它似乎它不起作用我在5个设备中测试游戏并且它不起作用，船总是在修复的地方并且它没有移动，但是如果我点击构建并从xcode开始它在所有的开发者设备我使用下面的代码：

在init

中

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

加速度计handeler：

- (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);

}

并在更新中：

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

Answer 1

解决方案是替换：

UIAccelerationValue rollingX;

通过

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