Alloy Pull to Refresh Widget

NOTE: Starting TiSDK 6.2 this widget is no longer needed as RefreshControl is build in for Android like previously for iOS, you can stick with the Ti.UI.RefreshControl

The Alloy Pull to Refresh widget is a cross-platform no-brainer wrapper of Ti.UI.RefreshControl for iOS and Ivan's fork of Ti.SwipeRefreshLayout for Android.

Before version 2.0.0 this widget emulated the native Pull to Refresh concept for Ti.UI.TableView on both platforms. Since 2.0.0 it uses the native controls now available in Titanium Core and through Ivan's module for both Ti.UI.TableView and Ti.UI.ListView.

Also take a look at the Infinite Scroll widget.

Examples

Android

iOS

Usage

1. Download and install the distribution 0.4.1 or later of Ivan's fork of Ti.SwipeRefreshLayout.

2. Install the widget via gitTio:

   gittio install nl.fokkezb.pullToRefresh

Or NPM:

`npm i --save nl.fokkezb.pulltorefresh`

3. Wrap the widget around your <ListView> or <TableView> in the view:

    <Alloy>
    	<Collection src="myCollection" />
    	<Window>
    		<Widget id="ptr" src="nl.fokkezb.pullToRefresh" onRelease="myRefresher">
    			<ListView>
    				<ListSection dataCollection="myCollection">
    					<ListItem title="{title}" />
    				</ListSection>
    			</ListView>
    		</Widget>
    	</Window>
    </Alloy>
   

   NOTE: The <Widget /> tag can't be the root element due to an Alloy limitation!

4. Add your myRefresher function to the controller and call the e.hide() callback when you're done:

    function myRefresher(e) {
    	myCollection.fetch({
    		success: e.hide,
    		error: e.hide
    	});
    }
   

5. Call the widget's refresh() to programmatically trigger the (initial) refresh:

    $.ptr.refresh();
   

6. To pass arguments to Ti.UI.createRefreshControl and createSwipeRefresh() simply pass them to the widget as attributes of <Widget> or second arguments of createWidget().
