iOS SDK Release Notes

Engineering Portal / Digital / iOS SDK Release Notes

Release 6.0.0.2 (1-18-2018)

DCR and DTVR Products Only

• Vizu Library Changes: AppSDK requires a code change to fix a critical bug pertaining to Viewability as requested by Vizu(VI) library team. AppSDK will subscribe to VI JS event VIExternalDataReady, which will ensure VI library is ready to provide the time series data.
• Static Ping Upload Failure: Issue occurs during 2 SDK instances. If instance 1 is destroyed and the second instance is still active, broadcast notification is sent to cancel all the pending requests and the session object is destroyed for both. Fix applied to isolate this notification for the destroyed instance only so it will not impact the other instance.
• SegA/B/C Fix: If empty values are provided for segA, segB, segC in the loadmetadata call, then SDK will use the default values from the config.
• DTVR Fix: Issue was introduced in v6.0.0.1 where tsv value was getting reset to default after pause. Issue occurred after pause when "stop", "play" and "loadMetadata" methods are called and the tsv flag gets reset to the default value 99 until another tsv request is fired.

Release 6.0.0.1 (12-14-2017)

All Products

The below updates apply to all products. They do not require code changes. Please check your product's implementation guide for detailed instructions on how to implement best measurement of your product.

• Appname Removal: Client will no longer need to pass Appname as part of SDK initialization because SDK will be retrieving the name from the application Info.plist file for iOS. Even if client continues to pass the Appname, SDK will ignore it.
• Default Privacy Url: Return default US privacy url instead of “nil” or blank string for userOptOutURLString.
• Event Data Reporting: Sending event data in milliseconds compared to seconds for more granular reporting.
• Minor Playhead Error: SDK will no longer send view ping if the first playhead position is 0 and if the playhead position is not incrementing. SDK will check if the playhead position will increment from 0 and then only send the view ping.
• Session Id Change: Updated the Session id format to align the AppSDK with the DAR/Browser SDK logic which generates 39 chars sessionid/uaid.

DCR and DTVR

Affected content types are DCR and DTVR.

• Viewability: Viewability is as an online tracking mechanism introduced in Nielsen SDK for representing the visibility of a video in the player along a playback that are actually viewed by the customers.
• Simplified SDK API: This will allow clients to have a simple interface to pass metadata to the sdk and reduce the number of api calls. This feature will currently be available for AppSDK only. New API (trackEvent) is introduced to simplify SDK integration for clients. New API will be implemented as a wrapper for the existing SDK API. Clients will be able to use either new or old SDK API.
• Bug Fix For DTVR: Fix for DTVR short ping having at parameter as “timer” instead of “sfview” during channel change scenario. iOS fix for 1 trans ping per ID3 tag.
• Stop Event Requirement Change: ST event will be reported at the end of the content, on End API call regardless of playhead position and channel change.
