GoogleMaps Framework Reference

AI-generated Key Takeaways

• This documentation outlines globally available enumerations for the Google Maps SDK for iOS.

• Enumerations define constants for marker behaviors, geocoder error codes, map capabilities, and more.

• GMSCollisionBehavior dictates how markers interact, prioritizing 'required' over 'optional' and higher zIndex values.

• GMSMapViewType lists display types for the map view like 'normal', 'satellite', 'hybrid', and 'terrain'.

• Other enumerations manage aspects like frame rates, padding adjustments, marker animations, and panorama sources.

Enumerations

The following enumerations are available globally.

• GMSCollisionBehavior

  How markers interact with other markers and regular labels. Defaults to GMSCollisionBehaviorRequired.

  Marker collisions occur when coordinates intersect.

  Priority is defined as: 1) Required > Optional 2) zIndex: higher zIndex > lower zIndex

  Beyond this, it is undefined which marker will show if both are optional and have the same zIndex. Regular map labels are the lowest priority.

  Declaration

  Swift

  enum GMSCollisionBehavior : Int, @unchecked Sendable

  Objective-C

  enum GMSCollisionBehavior : NSInteger {}

• GMSGeocoderErrorCode

  GMSGeocoder error codes, embedded in NSError.

  Declaration

  Swift

  enum GMSGeocoderErrorCode : Int, @unchecked Sendable

  Objective-C

  enum GMSGeocoderErrorCode : NSInteger {}

• GMSMapCapabilityFlags

  Flags that represent conditionally-available map capabilities (ones that require a mapID or some other map setting) that can be used to indicate availability.

  Declaration

  Swift

  struct GMSMapCapabilityFlags : OptionSet, @unchecked Sendable

  Objective-C

  enum GMSMapCapabilityFlags : NSUInteger {}

• GMSMapViewType

  Display types for GMSMapView.

  Declaration

  Swift

  enum GMSMapViewType : UInt, @unchecked Sendable

  Objective-C

  enum GMSMapViewType : NSUInteger {}

• GMSFrameRate

  Rendering frame rates for GMSMapView.

  Declaration

  Swift

  enum GMSFrameRate : UInt, @unchecked Sendable

  Objective-C

  enum GMSFrameRate : NSUInteger {}

• GMSMapViewPaddingAdjustmentBehavior

  Constants indicating how safe area insets are added to padding.

  Declaration

  Swift

  enum GMSMapViewPaddingAdjustmentBehavior : UInt, @unchecked Sendable

  Objective-C

  enum GMSMapViewPaddingAdjustmentBehavior : NSUInteger {}

• GMSMarkerAnimation

  Animation types for GMSMarker.

  Declaration

  Swift

  enum GMSMarkerAnimation : UInt, @unchecked Sendable

  Objective-C

  enum GMSMarkerAnimation : NSUInteger {}

• GMSPanoramaSource

  Source types for Panoramas. Used to specify the source of a StreetView Panorama.

  This API is experimental. Results may not always match expectations.

  Declaration

  Swift

  enum GMSPanoramaSource : UInt, @unchecked Sendable

  Objective-C

  enum GMSPanoramaSource : NSUInteger {}

• GMSLengthKind

  GMSLengthKind indicates the type of a length value, which can be geodesic (in meters), rhumb length (in meters) and projected length (in GMSMapPoint units).

  Declaration

  Swift

  enum GMSLengthKind : UInt, @unchecked Sendable

  Objective-C

  enum GMSLengthKind : NSUInteger {}
