如何处理。

Answer 1

你们必须放弃所掌握的数据。这一原则非常简单,一读“。仅仅无视今后二者的所有价值观。

你可能希望考虑使敏感度(延误)可以预测。

例:

NSDate *start = [NSDate date];

-(void)method:(UIAccelerometer *)accelerometer {
    NSTimeInterval timeInterval = [start timeIntervalSinceNow];
    /* if our last shake was more than 1 second ago */
    if(timeInterval > 1.0){
        /* do yourthing here */
        start = [NSDate date];
    }
}

Answer 2

也许问题在于,你发现加速度仪数据的每一小变化。我使用以下代码探测平均扫描:

- (void) accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration 
{
    if(sqrt(acceleration.x*acceleration.x + acceleration.y*acceleration.y + acceleration.z*acceleration.z)>3.0)
    {
        [self DoSomething];
    }
}

你们可以改变3.0%的数值,以发现更强/更小的螺。
