Implementation Options In Tag Integration, under the tab "Screens," you can set screen parameters. | Parameter | Description | | --- | --- | | classname | Specify the view controller name for which the following settings apply. | | mappingname | Specify an alternative content ID for this view controller. | | autoTracked | Specify whether automatic tracking is enabled for this view controller: true = activated false = deactivated > Please be aware that this setting will overwrite the "Track screen automatically" configuration in the "Basis" tab (see "[Basis](/v1/docs/basis)"). | In contrast to the global tracking parameters, the screen parameters are only available within the view controller. In the source code of your app, all parameters assigned to a tracker object within a view controller are automatically screen parameters. **Example** ```java import UIKit import Webtrekk class ProductListViewController: UITableViewController {  private  override func viewDidAppear(animated: Bool) {   super .viewDidAppear(animated)   let tracker = WebtrekkTracking.instance().trackerForPage( "Product List" )   tracker.pageProperties.groups = [     1 : "de" ,     2 : "home"   ]   tracker.trackPageView()  } } ``` Unlike the global tracking parameters, the activity parameters are only available to you within the scope of the activity. All parameters assigned to a TrackingParameter object within an activity in the source code of your app are automatically activity parameters. **Example** ```java // Example for a tracking call with an object TrackingParameter private Webtrekk webtrekk; private TrackingParameter tp; [...] @Override protected void onCreate(Bundle savedInstanceState) {  super .onCreate(savedInstanceState);  setContentView(R.layout.activity_main);  webtrekk = Webtrekk.getInstance();  tp = new TrackingParameter();  tp.add(Parameter.PAGE_CAT, "1" , "de" );  tp.add(Parameter.PAGE_CAT, "2" , "home" ); } @Override public void onStart() {   super .onStart();   // no track call, because autoTracked is enabled   // webtrekk.track(tp);  }  [...] ```
