Protocols
The following protocols are available globally.
-
A delegate for events on GMSMapView related to the navigation UI.
Declaration
Swift
protocol GMSMapViewNavigationUIDelegate : NSObjectProtocol
Objective-C
@protocol GMSMapViewNavigationUIDelegate <NSObject>
-
Protocol defining methods that support custom views specifying accessory UI elements applied to
the primary view. Accessory views must implement this protocol in order to be visible.
Declaration
Swift
protocol GMSNavigationAccessoryView : NSObjectProtocol
Objective-C
@protocol GMSNavigationAccessoryView <NSObject>
-
Protocol for returning information about screen metrics.
This protocol is a subset of the screen-metric-related properties implemented by UIScreen.
Declaration
Swift
protocol GMSNavigationScreenMetrics
Objective-C
@protocol GMSNavigationScreenMetrics
-
Declaration
Swift
protocol GMSNavigatorListener : NSObjectProtocol
Objective-C
@protocol GMSNavigatorListener <NSObject>
-
Declaration
Swift
protocol GMSRoadSnappedLocationProviderListener : NSObjectProtocol
Objective-C
@protocol GMSRoadSnappedLocationProviderListener <NSObject>
-
An interface representing a feature’s metadata.
Do not save a reference to a particular feature object because the reference will not be stable.
Declaration
Swift
protocol Feature : NSObjectProtocol
Objective-C
@protocol GMSFeature <NSObject>
-
Declaration
Swift
protocol GMSIndoorDisplayDelegate : NSObjectProtocol
Objective-C
@protocol GMSIndoorDisplayDelegate <NSObject>
-
Declaration
Swift
protocol GMSMapViewDelegate : NSObjectProtocol
Objective-C
@protocol GMSMapViewDelegate <NSObject>
-
Declaration
Swift
protocol GMSPanoramaViewDelegate : NSObjectProtocol
Objective-C
@protocol GMSPanoramaViewDelegate <NSObject>
-
GMSTileReceiver is provided to GMSTileLayer when a tile request is made, allowing the
callback to be later (or immediately) invoked.
Declaration
Swift
protocol GMSTileReceiver : NSObjectProtocol
Objective-C
@protocol GMSTileReceiver <NSObject>
