initWithAppInfo:delegate:

Engineering Portal / Digital / iOS SDK API Reference / initWithAppInfo:delegate:

Syntax

– (instancetype)initWithAppInfo:(id)appInfo delegate:(id)delegate;

Here, appInfo is a JSON formatted string or NSDictionary object that includes identification of the app.

Init JSON

• Call initWithAppInfo:delegate: to initialize a Nielsen App SDK object.
• The complete list of arguments that can be passed via the AppInfo JSON schema for the API are as follows.
  • The appid is provided by the Nielsen Technical Account Manager (TAM). The appid is a GUID data type and is specific to the application.

Parameter / Argument	Description	Source	Required?	Example
appid	Unique id for the application assigned by Nielsen. It is GUID data type. Use Test appid during development, test, and certification processes Use Production appid to submit app to App / Play store, after receiving Nielsen certification.	Nielsen-specified	Yes	PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
appname	Name of the application	Client-defined	Yes	Nielsen Sample App
appversion	Current version of the app used	SDK generated	Yes	"1.0.2"
sfcode	Nielsen collection facility to which the SDK should connect. DTVR "us" for production DCR "dcr" for production	Nielsen-specified	Yes	dcr
longitude	This value will not be overwritten by SDK for International (Germany).	Client-defined	No	123.22
latitude	This value will not be overwritten by SDK for International (Germany).	Client-defined	No	-123.22
dma	Nielsen Designated Market Area code. DMA must be the Nielsen DMA value. Please check with the Technical Account Manager.	Client-defined	No	123
ccode	If Country Code is provided by the app, it should be done after consultation with the Technical Account Manager.	Client-defined	No	456

Return Values

The application should check for valid return values like:

• Initialized NielsenAppApi object of type id.
• NIL object, if the initialization failed

Note: The minimum version supported by SDK is iOS 7. The app may not compile or the call to initWithAppInfo:delegate: will fail if Nielsen App SDK is initialized on devices with iOS versions 6.x and earlier.

Debug flag for development environment

Player application developers / integrators can use Debug flag to check whether an App SDK API call made is successful. To activate the Debug flag,

• Pass the argument @"nol_devDebug":@"INFO", in the JSON string for initWithAppInfo:delegate:, as below. The permitted values are
  • INFO: Displays the API calls and the input data from the application (validate player name, app ID, etc.). It can be used as certification Aid.
  • WARNING: Indicates potential integration / configuration errors or SDK issues.
  • ERROR: Indicates important integration errors or non-recoverable SDK issues.
  • DEBUG: Debug logs, used by the developers to debug more complex issues.

Example

NSDictionary* appInformation = @
         {
            @"appid": @"appid",
            @"appname": @"appname",
            @"appversion": @"2.0"
            @"sfcode": @"sfcode",
            @"nol_devDebug": @"INFO"
         };
nlsAppApiMeter = [[NielsenAppApi alloc] initWithAppInfo:appInformation delegate:self];

Once the flag is active, it logs each API call made and the data passed. The log created by this flag is minimal.

Note: DO NOT activate the Debug flag in a production environment.
