我完成了我的游戏（cocos2d），但是当我做一个存档（从xcode产品 - >存档），然后点击共享（获取game.api），然后把它放入itunes并同步到我的iphone它看起来没有工作的加速度计我在5个设备上测试了游戏，并且它没有工作，船总是在固定的位置，它并没有移动，但是如果我点击构建并从xcode去正常工作在所有的开发设备我用下面的代码：cocos2d +加速度计问题
在init里面
- (id)init
{
if ((self = [super init]))
{
self.isAccelerometerEnabled = YES;
[self scheduleUpdate];
}
加速度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;
}
船位置：
- (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);
}
和在更新：
- (void)update:(ccTime)dt {
...
[self updateShipPos:dt];
...}
