Add loading footer on UITableView - ios

Question

I have a UITableView. When I scroll to the bottom it loads more data. How can I add a loading animation to the footer of the table when it´s scrolled to the bottom?

Answer 1

You can use MNMBottomPullToRefreshManager file to load more data. First you have to initialize it in viewDidLoad as
pullToRefreshManager_ = [[MNMBottomPullToRefreshManager alloc] initWithPullToRefreshViewHeight:60.0f tableView:table withClient:self];
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
[pullToRefreshManager_ tableViewScrolled];
}
- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate: (BOOL)decelerate
{
[pullToRefreshManager_ tableViewReleased];
}
- (void)bottomPullToRefreshTriggered:(MNMBottomPullToRefreshManager *)manager
{
//method to get more data
// [self CallWebServiceToLoadMorePAYMENTS];
}
}
After reloading your tableView call:
[pullToRefreshManager_ tableViewReloadFinished];

Try this
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section {
UIView *headerView = [[[UIView alloc] init]autorelease];
[headerView setBackgroundColor:[UIColor clearColor]];
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self
action:#selector(aMethod:)
forControlEvents:UIControlEventTouchDown];
[button setTitle:#"Load More" forState:UIControlStateNormal];
button.frame = CGRectMake(10.0, 210.0, 160.0, 40.0);
[headerView addSubview:button];
return headerView;
}

Use this:
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
if(array.count>1){
if(indexPath.row == array.count-1){
[self setupTableViewFooter];
}
}
}
- (void)setupTableViewFooter
{
// set up label
UIView *footerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.navigationController.navigationBar.frame.size.height)];
footerView.backgroundColor = [UIColor clearColor];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectZero];
label.font = [UIFont fontWithName:Font_MuseoSans size:14];
label.autoresizingMask = UIViewAutoresizingFlexibleWidth;
label.textColor = [UIColor darkGrayColor];
label.text = #"Loading";
self.footerLabel = label;
CGSize labelSize = [self.footerLabel sizeThatFits:footerView.frame.size];
[footerView addSubview:self.footerLabel];
// set up activity indicator
UIActivityIndicatorView *activityIndicatorView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
activityIndicatorView.hidesWhenStopped = YES;
activityIndicatorView.color = [UIColor blackColor];
self.activityIndicator = activityIndicatorView;
[self.activityIndicator startAnimating];
[footerView addSubview:self.activityIndicator];
CGRect footerFrame = footerView.frame;
label.frame = CGRectMake((footerFrame.size.width-labelSize.width - 4 - activityIndicatorView.frame.size.width)/2, (footerFrame.size.height-labelSize.height)/2
, (footerFrame.size.width-labelSize.width - 4 - activityIndicatorView.frame.size.width), labelSize.height);
self.activityIndicator.frame = CGRectMake(label.frame.origin.x + labelSize.width + 4, (footerFrame.size.height-activityIndicatorView.frame.size.height)/2
, activityIndicatorView.frame.size.width, activityIndicatorView.frame.size.height);
self.tableView.tableFooterView = footerView;
}
