API Call sequence

Call loadMetadata with JSON metadata as below.

Swift

 
let staticMetadata = [
        "type": "static",
        "assetid": "C77664",
        "section": "siteSection",
        "segA": "segmentA",
        "segB": "CustomSegmentValueB", //optional
        "segC": "CustomSegmentValueC", //optional
];

Objective C

 
NSDictionary * staticMetadata = @ {
    @ "type": @ "static",
        @ "assetid": @ "C77664",
        @ "section": @ "siteSection",
        @ "segA": @ "Segment A",

Nielsen Measurement Opt-Out Implementation

As a global information and measurement leader, we are committed to protecting the privacy and security of the data we collect, process and use. Our digital measurement products are not used to identify the consumer in any way, but they help us and our clients measure and analyze how consumers engage with media across online, mobile and emerging technologies, and offer insights into consumer behavior.

• When the app user wants to opt in or opt out of Nielsen measurement, a new dynamic page (with content string obtained from optOutURL) should be displayed.
• Use optOutStatus to retrieve the device’s Opt-Out status.
• This Opt-out page should be displayed in a webview (within the app) and not in any external browser.
• Capture the user’s selection in this page and pass it to the SDK through userOptOut for Nielsen to save the user’s preference.
• For more details, refer to iOS SDK API Reference - iOS Opt-Out Implementation and Nielsen Digital Privacy.

Pre-Certification Checklists

After the application is ready to be sent for Nielsen Certification, please go through the Pre-Certification Checklist and ensure the app behaves as expected, before submitting to Nielsen.
