Return Personalization

Use this code when you are requesting and serving personalized product recommendations.

Replace <placement name> with your Placement name. You can find a list of placements in your Dashboard.

#import <RichRelevanceSDK/RichRelevanceSDK.h>

RCHRequestPlacement *placement = [[RCHRequestPlacement alloc] initWithPageType:RCHPlacementPageTypeHome name:@"<placement name>"];
    
RCHPlacementRecsBuilder *builder = [RCHSDK builderForRecsWithPlacement:placement];
      __block RCHRecommendedProduct *product;
[[RCHSDK defaultClient] sendRequest:[builder build] success:^(id responseObject) {
    RCHPlacementsResult *result = responseObject;
    RCHPlacement *placement = result.placements[0];
    product = placement.recommendedProducts[0];
} failure:^(id responseObject, NSError *error){
    // Use this code block to handle any errors that may occur while loading recommendations.
    NSLog(@"Error encountered: %@", error);
}];

Calling multiple placements

If you want to call multiple placements, simply initialize a builder with a nil placement, then define your placements and pass them to builder:addPlacement. You can also create a list such as a NSArray and iterate with a for..in loop.

IMPORTANT Placements must always be of the same type per request.

    NSArray *placements = @[
                            [[RCHRequestPlacement alloc] initWithPageType:RCHPlacementPageTypeHome name:@"recs_top"],
                            [[RCHRequestPlacement alloc] initWithPageType:RCHPlacementPageTypeHome name:@"recs_middle"]
                            ];
    
    RCHPlacementRecsBuilder *builder = [RCHSDK builderForRecsWithPlacement:nil];
    for (RCHRequestPlacement *placement in placements) {
        [builder addPlacement:placement];
    }
    
    [[RCHSDK defaultClient] sendRequest:builder success:^(id responseObject) {
        // Add your display logic here
    } failure:^(id responseObject, NSError *error) {
        // Add your error handling logic here
    }];

Listening Mode

When you do not render personalization in your Home UX, you must still send a Home request using the SDK. This is required so that RichRelevance can gather usage data in order to train your personalization models. In this specific case, you will create a listening placement. Listening placements are a special type of placement that can only log usage data without returning personalization data.

#import <RichRelevanceSDK/RichRelevanceSDK.h>

RCHRequestPlacement *placement = [[RCHRequestPlacement alloc] initWithListeningPageType:RCHPlacementPageTypeHome];    
RCHPlacementRecsBuilder *builder = [RCHSDK builderForRecsWithPlacement:placement];
[[RCHSDK defaultClient] sendRequest:[builder build]];
