SKSensorTimestamp

Objective-C

@interface SKSensorTimestamp : NSObject <NSCopying>

Swift

class SKSensorTimestamp : NSObject, NSCopying

SKSensorTimestamp object represent a single point in time.

  • Unavailable

    Undocumented

    Declaration

    Objective-C

    - (instancetype)init NS_UNAVAILABLE;

  • Creates and returns a new SKSensorTimestamp from an NSDate object. If the sensor does not provide an NSDate object, [NSDate date] can be used.

    Declaration

    Objective-C

    + (nonnull instancetype)sensorTimestampFromDate:(nonnull NSDate *)date;

    Swift

    convenience init(from date: Date)

    Parameters

    date

    The absolute date that this SKSensorTimestamp object should be initialized with.

    Return Value

    A new SKSensorTimestamp object initialized with the (NSDate *)date parameter.

  • 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.

    Declaration

    Objective-C

    + (nonnull instancetype)sensorTimestampFromTimeInterval:
    (NSTimeInterval)timeInterval;

    Swift

    convenience init(fromTimeInterval timeInterval: TimeInterval)

    Parameters

    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.

  • Returns an NSDate object of the sensor timestamp.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly) NSDate *_Nonnull timestamp;

    Swift

    var timestamp: Date { get }

  • Returns the interval between the timestamp and the last time the device was boot.

    Declaration

    Objective-C

    @property (nonatomic, readonly) NSTimeInterval timeIntervalSinceLastBoot;

    Swift

    var timeIntervalSinceLastBoot: TimeInterval { get }

  • Returns a dictionary that encapsulates the timestamp as a string, the interval since 1970, and the interval since the device was boot.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly) NSDictionary *_Nonnull timestampDictionary;

    Swift

    var timestampDictionary: [AnyHashable : Any] { get }

  • Returns a string representation of the timestamp. The format of the string is “yyyy-MM-dd HH:mm:ss.SSS ZZZ”.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly) NSString *_Nonnull timestampString;

    Swift

    var timestampString: String { get }

  • Returns the interval between the timestamp and 00:00:00 UTC on 1 January 1970.

    Declaration

    Objective-C

    @property (nonatomic, readonly) NSTimeInterval timeIntervalSince1970;

    Swift

    var timeIntervalSince1970: TimeInterval { get }
