iOS Segment Support

Applies to TestComplete 15.65, last modified on July 17, 2024
The information below concerns legacy mobile tests that work with mobile devices connected to the local computer. In new cloud-compatible mobile tests, the test engine recognizes controls by their accessibility info.

About Support

Segmented controls in iOS applications group several segments and are used to provide a user with a choice among a set of options. A user can select a segment by touching it.

The image below demonstrates a sample segmented control containing three segments:

Segmented Control

TestComplete can recognize individual segments of segmented controls in iOS applications. It provides special properties and methods that let you retrieve the controls data and simulate user actions on the controls (see below).

Note: To work with a segmented control as an integral control in tests, use the iOS SegmentedControl test object.


In order for TestComplete to be able to work with iOS Segment controls, the following requirements must be met:

  • You must have an active license for the TestComplete Mobile module.

  • Your tested iOS application, the devices and the computer where TestComplete runs must be configured in a special way as it is described in the topics of the Preparing Applications, Devices, and Test Computers for iOS Testing (Legacy) section.

  • The control’s class name must be specified in the iOS Controls | Segment group of your project’s Object Mapping options. By default, this group contains the following item:

    • UISegment

    To command TestComplete to recognize instances of the specified class’s descendants as iOS Segment controls, select the Derived Classes check box next to the control’s class name.

    You can also command the test engine to recognize custom controls as iOS Segment controls. See below for information about this.

  • Support for the iOS Segment controls is implemented by the iOS Support plugin. This plugin is installed and enabled automatically as part of the TestComplete Mobile module.

    If you experience issues when working with the controls, select File > Install Extensions from the TestComplete main menu and check whether the plugin is active. (You can find the plugin in the Mobile group.) If the plugin is not available, run the TestComplete installation in the Repair mode.

Recognizing Custom Controls

To command TestComplete to recognize your custom controls as iOS Segment controls:

  1. Open your project’s Object Mapping options.

  2. Add the control’s class name to the iOS Controls | Segment group.

    If you do not know the control’s name, you can ask the control’s developers, or you can view the control’s ObjectClassName property in the Object Browser panel. As an alternative, you can click Add From Screen and select your custom control on screen. TestComplete will retrieve the control’s class name and add it to the selected mapping group automatically. For detailed information, see Object Mapping.

Once the control is mapped, it gets all the properties, methods and actions specific to the iOS Segment control.

If the specified custom control does not fit the control’s type, then it may not properly respond to commands that TestComplete sends, so recording or playing back user actions over the tested control will cause errors.


When testing iOS Segment controls, you can use properties and methods specific to these controls, as well as properties and methods that TestComplete applies to tested objects, onscreen objects and window objects. For the full list of available properties and methods, see the following topics:
