使用设备运动管理器的目标C/iOS更新间隔问题

代码用于获取运动和陀螺仪更新，分别放入阵列中，并在发生捕获事件时选择阵列中的最大值。如果设备运动更新设置为.02或.03，则一切正常；但是，当更新设置为应用程序所需的.01时，我将获得额外的输出/值。任何帮助或指导都将不胜感激。提前谢谢。代码如下：`

#import "ViewController.h"
#import <CoreMotion/CoreMotion.h>

#define kRadToDeg   57.2957795

for（int i=0；i只是想为任何有类似问题的人共享解决方案。在上面的checkCapture方法中停止设备运动更新后，我添加了一个延迟，并将“for循环”移动到一个单独的方法中-如下所示：

[self performSelector:@selector(adjustValues) withObject:nil afterDelay:.5];

-(void)adjustValues {
 for (int i=0; i<30; i++){ // modify pitchArray to remove last 30 values
    [self.pitchArray removeLastObject];

 id maxPitch = [_pitchArray valueForKeyPath:@"@max.integerValue"];

 _maxPitch = maxPitch;

 [self outputValues];
