The Xamarin.iOS pull-to-refresh control provides a panel that can be pulled to refresh the data in an application through user interaction or programmatically. The appearance and transition of the progress indicator can be customized.
Animate transitions between the pullable content and the refresh indicator when performing a pull operation. The two types of built-in transitions are:
Load complex views such as list view, data grid, and other custom layouts as pullable content and refresh the data through a pulling action.
Customize the appearance of the progress indicator and transition animation for a better user experience and to achieve a platform-specific native look and feel.
The following aspects can be customized: background color of the progress indicator, stroke color of the progress indicator, stroke width of the progress indicator, height and width of the progress view, pulling threshold (distance of the pulling transition), and refresh content threshold (starting position of the progress view).
