As drmatt metioned, you should look into Pull to refresh demo
http://cubiq.org/dropbox/iscroll4/examples/pull-to-refresh/
You need to build you own logic which won't require user to pull to add more items.
Something like following (pseudo code - not tested code):
var isAlreadyLoading = 0;
var iscroller = new iScroll(
'your-element-id',
{
hScroll: false,
bounce: false, // do not bounce
onScrollMove: function () {
// CHECK if we've 350px gap before reaching end of the page
if ( (this.y < (this.maxScrollY + 350)) && (isAlreadyLoading == 0) ){
// start loading next page content here
// update this flag inside load more and set to 0 when complete
isAlreadyLoading = 1;
}
},
onScrollEnd: function () {
// check if we went down, and then load content
if ( isAlreadyLoading == 0 ) {
// Load more content
// update this flag inside load more and set to 0 when complete
isAlreadyLoading = 1;
} else {
// DO NOTHING
}
}
} // end of Scoller config object
); // end iScroll instance
