Changes

When the user touches the text field, the keyboard will appear. By default this will display a “Return” key. For the purposes of this application, however, a “Search” key would be more appropriate. To make this modification, select the new Text Field object, display the Attributes Inspector and change the Return Key setting from Default to Search.

Next, display the Assistant Editor panel and make sure that it is displaying the content of the MapSampleViewController.h file. Ctrl-click on the Text View object and drag the resulting line to the Assistant Editor panel and establish an outlet named searchText.
