The products variable cannot be set by using processing rules. In the iOS 4.x SDK, you must use a special syntax in the context data parameter to set products directly on the server call.
To set the products variable, set a context data key to "&&products", and set the value by using the syntax that is defined for the products variable:
[contextData setObject:@"Category;Product;Quantity;Price[,Category;Product;Quantity;Price]" forKey:@"&&products"];For example:
//create a context data dictionary
NSMutableDictionary *contextData = [NSMutableDictionary dictionary];
// add products, a purchase id, a purchase context data key, and any other data you want to collect.
// Note the special syntax for products
[contextData setObject:@";Running Shoes;1;69.95,;Running Socks;10;29.99" forKey:@"&&products"];
[contextData setObject:@"1234567890" forKey:@"m.purchaseid"];
[contextData setObject:@"1" forKey:@"m.purchase"];
// send the tracking call - use either a trackAction or TrackState call.
// trackAction example:
[ADBMobile trackAction:@"purchase" data:contextData];
// trackState example:
[ADBMobile trackState:@"Order Confirmation" data:contextData];
products is set directly on the image request, and the other variables are set as context data. All context data variables must be mapped by using processing rules:
You do not need to map the products variable using processing rules because it is set directly on the image request by the SDK.
