A user interface element within Apple’s mobile operating system that allows users to select a numerical value from a predefined range. Typically presented as a rotating wheel or series of wheels, it enables precise and efficient selection of numbers, dates, times, or other quantitative data. For instance, within a settings menu, this control can be employed to adjust volume levels, set timers, or configure date and time preferences.
The control offers a streamlined method for inputting numerical data on touch-based devices, enhancing user experience by minimizing typing and potential errors. Its visual and interactive nature contributes to intuitive navigation and simplifies the process of choosing values within specified boundaries. This functionality has evolved over successive iOS iterations, reflecting refinements in design and responsiveness to user expectations regarding data entry and control.
