（转）iPhone 判断UITableView 滚动到底部

UITableView is a subclass of UIScrollView, and UITableViewDelegate conforms to UIScrollViewDelegate. So the delegate you attach to the table view will get events such asscrollViewDidScroll:, and you can call methods such as contentOffset on the table view to find the scroll position.

in the tableview delegate do something like this:

- (void)scrollViewDidScroll:(UIScrollView *)aScrollView {
	
	CGPoint offset = aScrollView.contentOffset;     
	CGRect bounds = aScrollView.bounds;     
	CGSize size = aScrollView.contentSize;     
	UIEdgeInsets inset = aScrollView.contentInset;     
	float y = offset.y + bounds.size.height - inset.bottom;     
	float h = size.height;     
	// NSLog(@"offset: %f", offset.y);       
	// NSLog(@"content.height: %f", size.height);       
	// NSLog(@"bounds.height: %f", bounds.size.height);       
	// NSLog(@"inset.top: %f", inset.top);       
	// NSLog(@"inset.bottom: %f", inset.bottom);       
	// NSLog(@"pos: %f of %f", y, h);     
	float reload_distance = 10;     
	if(y > h + reload_distance) {         
		//NSLog(@"load more rows");
		
		if(!isLoading)
			[self loadMore];
	} 
}
