Is there any way to fire a method,when we scroll down from the bottom of a UIWebView ? I have seen many answers but could not find a workable idea :(

UIWebView conforms to the UIScrollViewDelegate protocol.
UIWebView符合UIScrollViewDelegate协议。
The protocol defines the scrollViewDidScroll: (look it up here) method. If you implement it and set your object as the delegate of UIWebView you should get notified if the View scrolls. You can then ask the webview for its contentOffset and determine whether the scroll was upwards or downwards.
该协议定义了scrollViewDidScroll :(在此查找)方法。如果您实现它并将对象设置为UIWebView的委托,则应在View滚动时收到通知。然后,您可以向webview询问其contentOffset,并确定滚动是向上还是向下。
