Overview

Main interface to the Places SDK.

Used for searching and getting details about places. This class should be accessed through the [GMSPlacesClient sharedClient] method.

GMSPlacesClient methods should only be called from the main thread. Calling these methods from another thread will result in an exception or undefined behavior. Unless otherwise specified, all callbacks will be invoked on the main thread.

+ (instancetype) sharedClient

Provides the shared instance of GMSPlacesClient for the Google Places SDK for iOS, creating it if necessary.

If your application often uses methods of GMSPlacesClient it may want to hold onto this object directly, as otherwise your connection to Google may be restarted on a regular basis.

+ (BOOL) provideAPIKey: (NSString *) key

Provides your API key to the Google Places SDK for iOS.

This key is generated for your application via the Google Cloud Platform Console, and is paired with your application's bundle ID to identify it. This should be called by your application before using GMSPlacesClient (e.g., in application:didFinishLaunchingWithOptions:).

Returns:: YES if the APIKey was successfully provided.

+ (NSString *) openSourceLicenseInfo

Returns the open source software license information for the Google Places SDK for iOS.

This information must be made available within your application.

+ (NSString *) SDKVersion

Returns the version for this release of the Google Places SDK for iOS.

. For example, "1.0.0".

+ (NSString *) SDKLongVersion

Returns the long version for this release of the Google Places SDK for iOS.

. For example, "1.0.0 (102.1)".

- (void) lookUpPlaceID:	(NSString *)	placeID
callback:	(GMSPlaceResultCallback)	callback

Get details for a place.

This method is non-blocking.

Parameters:

placeID	The place ID to lookup.
callback	The callback to invoke with the lookup result.

- (void) lookUpPhotosForPlaceID:	(NSString *)	placeID
callback:	(GMSPlacePhotoMetadataResultCallback)	callback

Gets the metadata for up to 10 photos associated with a place.

Photos are sourced from a variety of locations, including business owners and photos contributed by Google+ users. In most cases, these photos can be used without attribution, or will have the required attribution included as a part of the image. However, you must use the attributions property in the response to retrieve any additional attributions required, and display those attributions in your application wherever you display the image. A maximum of 10 photos are returned.

Multiple calls of this method will probably return the same photos each time. However, this is not guaranteed because the underlying data may have changed.

This method performs a network lookup.

Parameters:

placeID	The place ID for which to lookup photos.
callback	The callback to invoke with the lookup result.

- (void) loadPlacePhoto:	(GMSPlacePhotoMetadata *)	photoMetadata
callback:	(GMSPlacePhotoImageResultCallback)	callback

Loads the image for a specific photo at its maximum size.

Image data may be cached by the SDK. If the requested photo does not exist in the cache then a network lookup will be performed.

Parameters:

photoMetadata	The `GMSPlacePhotoMetadata` for which to load a `UIImage`.
callback	The callback to invoke with the loaded `UIImage`.

- (void) loadPlacePhoto:	(GMSPlacePhotoMetadata *)	photoMetadata
constrainedToSize:	(CGSize)	maxSize
scale:	(CGFloat)	scale
callback:	(GMSPlacePhotoImageResultCallback)	callback

Loads the image for a specific photo, scaled to fit the given maximum dimensions.

The image will be scaled to fit within the given dimensions while maintaining the aspect ratio of the original image. This scaling is performed server-side.

If the scale parameter is not 1.0 maxSize will be multiplied by this value and the returned UIImage will be set to have the specified scale. This parameter should be set to the screen scale if you are loading images for display on screen.

Image data may be cached by the SDK. If the requested photo does not exist in the cache then a network lookup will be performed.

Note:: After applying the scale factor the dimensions in maxSize will be rounded up to the nearest integer before use. If an image is requested which is larger than the maximum size available a smaller image may be returned.

Parameters:

photoMetadata	The `GMSPlacePhotoMetadata` for which to load a `UIImage`.
maxSize	The maximum size of the image.
scale	The scale to load the image at.
callback	The callback to invoke with the loaded `UIImage`.

- (void) currentPlaceWithCallback: (GMSPlaceLikelihoodListCallback) callback

Returns an estimate of the place where the device is currently known to be located.

Generates a place likelihood list based on the device's last estimated location. The supplied callback will be invoked with this likelihood list upon success and an NSError upon an error.

Note:: This method requires that your app has permission to access the current device location. Before calling this make sure to request access to the users location using [CLLocationManager requestWhenInUseAuthorization] or [CLLocationManager requestAlwaysAuthorization]. If you do call this method and your app does not have the correct authorization status, the callback will be called with an error.

Parameters:

callback The callback to invoke with the place likelihood list.

- (void) findAutocompletePredictionsFromQuery:	(NSString *)	query
filter:	(nullable GMSAutocompleteFilter *)	filter
sessionToken:	(nullable GMSAutocompleteSessionToken *)	sessionToken
callback:	(GMSAutocompletePredictionsCallback)	callback

Find Autocomplete predictions from text query.

Results may optionally be biased towards a certain location or restricted to an area. This method is non-blocking.

The supplied callback will be invoked with an array of autocompletion predictions upon success and an NSError upon an error.

Parameters:

query	The partial text to autocomplete.
filter	The filter to apply to the results. This parameter may be nil.
sessionToken	The `GMSAutocompleteSessionToken` to associate request to a billing session.
callback	The callback to invoke with the predictions.

- (void) fetchPlaceFromPlaceID:	(NSString *)	placeID
placeFields:	(GMSPlaceField)	placeFields
sessionToken:	(nullable GMSAutocompleteSessionToken *)	sessionToken
callback:	(GMSPlaceResultCallback)	callback

Fetch details for a place.

This method is non-blocking.

Parameters:

placeID	The place ID to lookup.
placeFields	The individual place fields requested for the place objects in the list.
sessionToken	The `GMSAutocompleteSessionToken` to associate request to a billing session.
callback	The callback to invoke with the lookup result.

- (void) findPlaceLikelihoodsFromCurrentLocationWithPlaceFields:	(GMSPlaceField)	placeFields
callback:	(GMSPlaceLikelihoodsCallback)	callback

Find place likelihoods using the user's current location.

This method is non-blocking.

The supplied callback will be invoked with an array of places with likelihood scores upon success and an NSError upon an error.

Parameters:

placeFields	The individual place fields requested for the place objects in the list.
callback	The callback to invoke with place likelihoods.
