@interface FIRAnalytics : NSObject
The top level Firebase Analytics singleton that provides methods for logging events and setting user properties. See the developer guides for general information on using Firebase Analytics in your apps.
Logs an app event. The event can have up to 25 parameters. Events with the same name must have the same parameters. Up to 500 event names are supported. Using predefined events and/or parameters is recommended for optimal reporting.
The following event names are reserved and cannot be used:
class func logEvent(withName name: String, parameters: [String : NSObject]?)
+ (void)logEventWithName:(nonnull NSString *)name parameters: (nullable NSDictionary<NSString *, NSObject *> *)parameters;
The name of the event. Should contain 1 to 40 alphanumeric characters or underscores. The name must start with an alphabetic character. Some event names are reserved. See FIREventNames.h for the list of reserved event names. The
firebase_prefix is reserved and should not be used. Note that event names are case-sensitive and that logging two events whose names differ only in case will result in two distinct events.
The dictionary of event parameters. Passing nil indicates that the event has no parameters. Parameter names can be up to 40 characters long and must start with an alphabetic character and contain only alphanumeric characters and underscores. Only NSString and NSNumber (signed 64-bit integer and 64-bit floating-point number) parameter types are supported. NSString parameter values can be up to 100 characters long. The
firebase_prefix is reserved and should not be used for parameter names.
Sets a user property to a given value. Up to 25 user property names are supported. Once set, user property values persist throughout the app lifecycle and across sessions.
The following user property names are reserved and cannot be used:
class func setUserPropertyString(_ value: String?, forName name: String)
+ (void)setUserPropertyString:(nullable NSString *)value forName:(nonnull NSString *)name;
The value of the user property. Values can be up to 36 characters long. Setting the value to nil removes the user property.
The name of the user property to set. Should contain 1 to 24 alphanumeric characters or underscores and must start with an alphabetic character. The
firebase_prefix is reserved and should not be used for user property names.
class func setUserID(_ userID: String?)
+ (void)setUserID:(nullable NSString *)userID;
The user ID to ascribe to the user of this app on this device, which must be non-empty and no more than 36 characters long. Setting userID to nil removes the user ID.
Sets the current screen name, which specifies the current visual context in your app. This helps identify the areas in your app where users spend their time and how they interact with your app.
Note that screen reporting is enabled automatically and records the class name of the current UIViewController for you without requiring you to call this method. If you implement viewDidAppear in your UIViewController but do not call [super viewDidAppear:], that screen class will not be automatically tracked. The class name can optionally be overridden by calling this method in the viewDidAppear callback of your UIViewController and specifying the screenClassOverride parameter.
If your app does not use a distinct UIViewController for each screen, you should call this method and specify a distinct screenName each time a new screen is presented to the user.
The screen name and screen class remain in effect until the current UIViewController changes or a new call to setScreenName:screenClass: is made.
class func setScreenName(_ screenName: String?, screenClass screenClassOverride: String?)
+ (void)setScreenName:(nullable NSString *)screenName screenClass:(nullable NSString *)screenClassOverride;
The name of the current screen. Should contain 1 to 100 characters. Set to nil to clear the current screen name.
The name of the screen class. Should contain 1 to 100 characters. By default this is the class name of the current UIViewController. Set to nil to revert to the default class name.
Handles events related to a URL session that are waiting to be processed.
For optimal use of Firebase Analytics, call this method from the [UIApplicationDelegate application:handleEventsForBackgroundURLSession:completionHandler] method of the app delegate in your app.
class func handleEvents(forBackgroundURLSession identifier: String!, completionHandler: (() -> Void)!)
+ (void)handleEventsForBackgroundURLSession:(NSString *)identifier completionHandler:(void (^)(void))completionHandler;
The identifier of the URL session requiring attention.
The completion handler to call when you finish processing the events. Calling this completion handler lets the system know that your app’s user interface is updated and a new snapshot can be taken.
Handles the event when the app is launched by a URL.
Call this method from
UIApplicationDelegate application:openURL:options:, or
UIApplicationDelegate application:openURL:sourceApplication:annotation:in your app.
class func handleOpen(_ url: URL!)
+ (void)handleOpenURL:(NSURL *)url;
The URL resource to open. This resource can be a network resource or a file.
Handles the event when the app receives data associated with user activity that includes a Universal Link (on iOS 9.0 and above).
Call this method from [UIApplication continueUserActivity:restorationHandler:] in your app delegate (on iOS 9.0 and above).
class func handleUserActivity(_ userActivity: Any!)
The activity object containing the data associated with the task the user was performing.
