GMSPath

@interface GMSPath : NSObject <NSCopying, NSMutableCopying>

GMSPath encapsulates an immutable array of CLLocationCooordinate2D. All the coordinates of a GMSPath must be valid. The mutable counterpart is GMSMutablePath.

  • Convenience constructor for an empty path.

    Declaration

    Objective-C

    + (nonnull instancetype)path;

  • Initializes a newly allocated path with the contents of another GMSPath.

    Declaration

    Swift

    init(path: GMSPath)

    Objective-C

    - (nonnull id)initWithPath:(nonnull GMSPath *)path;

  • Get size of path.

    Declaration

    Swift

    func count() -> UInt

    Objective-C

    - (NSUInteger)count;

  • Returns kCLLocationCoordinate2DInvalid if index >= count.

    Declaration

    Swift

    func coordinate(at index: UInt) -> CLLocationCoordinate2D

    Objective-C

    - (CLLocationCoordinate2D)coordinateAtIndex:(NSUInteger)index;

  • Initializes a newly allocated path from -encodedPath. This format is described at: https://developers.google.com/maps/documentation/utilities/polylinealgorithm

    Declaration

    Swift

    convenience init?(fromEncodedPath encodedPath: String)

    Objective-C

    + (nullable instancetype)pathFromEncodedPath:(nonnull NSString *)encodedPath;

  • Returns an encoded string of the path in the format described above.

    Declaration

    Swift

    func encodedPath() -> String

    Objective-C

    - (nonnull NSString *)encodedPath;

  • Returns a new path obtained by adding deltaLatitude and deltaLongitude to each coordinate of the current path. Does not modify the current path.

    Declaration

    Swift

    func pathOffset(byLatitude deltaLatitude: CLLocationDegrees, longitude deltaLongitude: CLLocationDegrees) -> Self

    Objective-C

    - (nonnull instancetype)pathOffsetByLatitude:(CLLocationDegrees)deltaLatitude
                                   longitude:(CLLocationDegrees)deltaLongitude;

GMSPathLength

  • Returns the fractional number of segments along the path that correspond to length, interpreted according to kind. See GMSLengthKind.

    Declaration

    Swift

    func segments(forLength length: CLLocationDistance, kind: GMSLengthKind) -> Double

    Objective-C

    - (double)segmentsForLength:(CLLocationDistance)length kind:(GMSLengthKind)kind;

  • Returns the length of the path, according to kind. See GMSLengthKind.

    Declaration

    Swift

    func length(of kind: GMSLengthKind) -> CLLocationDistance

    Objective-C

    - (CLLocationDistance)lengthOfKind:(GMSLengthKind)kind;
