Pull to refresh functionality

What is the pull to refresh functionality?

Pull to refresh functionality is now a need of every mobile application. Using pull to refresh functionality, users can get the newly updated output from the application. Just by pulling down the application, the user will get the fresh content in the application. The ios application is simple to add pull to refresh functionality to tableview or collectview.

Implementation of Pull to refresh functionality

Apple provides us with a simple way to add this functionality to any application. The UIRefreshControl class simply adds this functionality to the application. First, we have to instantiate it.

Let refreshControl = UIRefreshControl()

After this, we have to add this property in Tableview, but we have to check the version because ios 10 doesn’t have any property like refreshControl.

if #available(ios 10.0, *)
     tableView.refreshControl = refreshControl

Now, as we want to perform some action by our application, we have to assign some target to it.

refreshControl.addTarget(self, action: #selector(function_:), for:.valueChanged)

This is how we are set to use the pull to refresh functionality in our application.

Importance of Pull to refresh functionality

Pull to refresh functionality is used to engage users while updating the data in the application. Using some animation and gesture effects in the application, the manufacturer just diverts the user's attention from the actual working.
