Overview I am using the CMMotionManager function to get the sensor data. Now there are 2apps reading the sensor at the same time. Question When I read the sensor, can other apps can read the sensor? Is the sensor data being distributed equally to the apps? Do the 2 apps have the exact same sensor data? How does the iOS sensor handle when there are multiple processes or apps reading the sensor? Will multiple processes or apps receive the exact same data? Is there a way to guarantee that the data read is unique.
