FIRVision
@interface FIRVision : NSObject
A Firebase service that supports vision APIs.
-
Enables stats collection in ML Kit vision. The stats include API call counts, errors, API call durations, options, etc. No personally identifiable information is logged.
The setting is per
FirebaseApp
, and therefore perVision
, and it is persistent across launches of the app. It means if the user uninstalls the app or clears all app data, the setting will be erased. The best practice is to set the flag in each initialization.By default the logging is enabled. You have to specifically set it to false to disable logging.
Declaration
Objective-C
@property (nonatomic, assign, unsafe_unretained, readwrite, getter=isStatsCollectionEnabled) BOOL statsCollectionEnabled;
-
