Sending events on iOS

You can send multi-level events in AppMetrica. For more information about displaying multi-level events, see Events.

To send a multi-level event, pass a key:value pair in the event parameters. In the interface, key and value are considered nesting levels. Event parameters can be sent as an NSDictionary object.

To send your custom event with nested parameters, use the +reportEvent:params:onFailure: method of the YMMYandexMetrica class:

NSDictionary *params = @{@"key1": @"value1", @"key2": @"value2"};
[YMMYandexMetrica reportEvent:@"EVENT"
                   parameters:params
                    onFailure:^(NSError *error) {
                        NSLog(@"error: %@", [error localizedDescription]);
                    }];
