Refreshing contented is a cornerstone of contemporary app plan. Customers anticipate a seamless manner to replace information, and the UIRefreshControl is a almighty implement successful the iOS developer’s arsenal. Historically, it’s tightly coupled with UITableViewController, however what if you’re utilizing a daily UIViewController with a UIScrollView oregon UICollectionView? This article dives heavy into implementing UIRefreshControl with out UITableViewController, offering applicable examples and adept insights to aid you elevate your app’s person education.

Decoupling UIRefreshControl from UITableViewController

The modular attack hyperlinks UIRefreshControl straight to a UITableViewController. Nevertheless, this limits its usage successful much analyzable layouts. Decoupling it permits for better flexibility and power, particularly once running with UICollectionView oregon customized scroll views. This attack provides you the state to customise the refresh behaviour and combine it seamlessly into divers UI paradigms.

By straight managing the UIRefreshControl inside a modular UIViewController, builders addition granular power complete the refresh procedure, permitting for tailor-made animations and interactions that heighten the person education past the modular implementation.

Wrong this relation, you ought to instrumentality the logic to fetch up to date information. Erstwhile the information is fetched, call refreshControl.endRefreshing() to halt the animation and show the fresh information.

Customization and Champion Practices

UIRefreshControl gives respective customization choices. You tin alteration the attributed rubric to supply suggestions to the person, specified arsenic “Past up to date connected…” You tin besides customise the refresh power’s tint colour to lucifer your app’s branding.

I frequently usage a UIViewController with a UITableView subview and conform to UITableViewDataSource and UITableViewDelegate instead than utilizing a UITableViewController outright.

Connected a hunch, and primarily based connected DrummerB’s inspiration, I tried merely including a UIRefreshControl case arsenic a subview to my UITableView. And it magically conscionable plant!

UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init]; [refreshControl addTarget:same act:@selector(handleRefresh:) forControlEvents:UIControlEventValueChanged]; [same.myTableView addSubview:refreshControl]; 

This provides a UIRefreshControl supra your array position and plant arsenic anticipated with out having to usage a UITableViewController :)

EDIT: This supra inactive plant however arsenic a fewer person pointed retired, location is a flimsy “stutter” once including the UIRefreshControl successful this mode. A resolution to that is to instantiate a UITableViewController, and past mounting your UIRefreshControl and UITableView to that, i.e.:

UITableViewController *tableViewController = [[UITableViewController alloc] init]; tableViewController.tableView = same.myTableView; same.refreshControl = [[UIRefreshControl alloc] init]; [same.refreshControl addTarget:same act:@selector(getConnections) forControlEvents:UIControlEventValueChanged]; tableViewController.refreshControl = same.refreshControl;
