Bottom-Referesh-Control-UITableView

Smooth scrolling bottom refresh control for table view with some objects in array.

Just add some dummy data into array with custom referesh control cell in table view or handle response from web service and populate the data into the array with smooth animation from table view top with this two methods

Make sure these given below methods are very important to show the cell at the end of the table view with your conditional array objects so that you can show the load more cell in table view with concerned API call for loading more data to an array.

Please go through the demo once and let me know if any query regarding this demo of bottom referesh control.

These were the methods to focus on while loading more data into cell with load more custom cell in table view as below:

Step 1 :

    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
        return self.objects.count + 1;
    }

Step 2 :

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
        static NSString *cellStandardIdentifier = @"Cell";
        static NSString *cellLoadingIdentifier = @"Loading";

        if (indexPath.row < self.objects.count) {
            UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellStandardIdentifier forIndexPath:indexPath];
            cell.textLabel.text = self.objects[indexPath.row];
            return cell;
        } else {
            LoadingTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellLoadingIdentifier forIndexPath:indexPath];
            [cell.activityIndicatorView startAnimating];
            [self fetchMoreData];
            return cell;
        }
    }

Step 3 :

    - (void)fetchMoreData {
        static BOOL fetchInProgress = FALSE;

        if (fetchInProgress)
            return;

        typeof(self) __weak weakSelf = self;

        fetchInProgress = TRUE;

        // this simulates a background fetch; I'm just going to delay for a second
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
            typeof(self) strongSelf = weakSelf;
            if (strongSelf) {
                NSArray *indexPaths = [strongSelf addSomeObjects];
                [strongSelf.tableView beginUpdates];
                [strongSelf.tableView insertRowsAtIndexPaths:indexPaths withRowAnimation:UITableViewRowAnimationTop];
                fetchInProgress = FALSE;
                [strongSelf.tableView endUpdates];
            }
        });
    }

Step 4 :

    - (NSArray *)addSomeObjects {
        NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
        formatter.numberStyle = NSNumberFormatterSpellOutStyle;
        NSMutableArray *indexPaths = [NSMutableArray array];
        for (NSInteger i = 0; i < 20; i++) {
            [self.objects addObject:[formatter stringFromNumber:@([self.objects count] + 1)]];
            [indexPaths addObject:[NSIndexPath indexPathForRow:self.objects.count - 1 inSection:0]];
        }
        return indexPaths;
    }
