A user interface element commonly found in applications developed for Apple’s operating system for mobile devices, this control presents a linear set of two or more segments, each functioning as a mutually exclusive button. Selecting one segment deselects all others. Functionally similar to radio buttons but occupying less screen real estate, it offers a compact method for users to choose between distinct, related options. An example would be an application displaying search results, where it might allow users to switch between viewing “Top,” “Latest,” and “People” results.
The primary benefit of this UI component is its ability to provide clear and immediate selection among a small set of mutually exclusive choices. Its use streamlines the user experience by presenting all options simultaneously, reducing the need for navigation through menus or multiple screens. Historically, this control has been a prominent design element within the iOS ecosystem, contributing to the platform’s recognizable user interface conventions. Its consistent application helps users quickly understand its function across various applications.
