SKSensorTimestamp.h
+ sensorTimestampFromTimeInterval:
Creates and returns a new SKSensorTimestamp from a NSTimeInterval object. The time interval should be relative to the last time the device was boot. If the sensor does not provide this value, [NSProcessInfo processInfo].systemUptime can be used.
+ (instancetype)sensorTimestampFromTimeInterval:(NSTimeInterval)timeIntervalParameters
timeInterval |
The number of seconds since the last time the device was boot. |
|---|
Return Value
A new SKSensorTimestamp object initialized relative to the timeInterval parameter.
