    <p>I have like 100 records to display on a table. But i will be only displaying 10 records, and when the user clicks the last row <code>(Which will have a button that will say load the next 10 records)</code> the table will row the next 10 records.</p> <p>I have displayed the more button on the last cell successfully. But i don't know how to display 10 records at a time. My code so far;</p> <p><strong>ViewDidLoad</strong></p> <pre><code>self.arrayThatContainsAllHundredRecords= [NSArray arrayWithArray:hundredRecordsArray]; [self performSelector:@selector(addTheTableFooter:) withObject:nil afterDelay:0.5]; </code></pre> <p><strong>addTheTableFooter</strong></p> <pre><code>UIView* footer = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 30)]; [footer addSubview:moreButton]; // i have also added an event to the button click see below, and i have not shown it here. self.tableView.tableFooterView =footer; [self.mainWindow removeFromSuperview]; [self.tableView reloadData]; </code></pre> <p>The above would Display the <code>More</code> button after displaying all <code>100</code> records.</p> <p><strong>moreButtonClickAction</strong></p> <pre><code>-(void)moreButtonClickAction { NSLog(@"Suppose to load the next 10 records"); } </code></pre> <p><strong>numberOfRowsInSection</strong></p> <pre><code>- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [self.arrayThatContainsAllHundredRecords count]; } </code></pre> <p>I need a way to edit this code, so i will only display 10 records at a time, and display the next 10 when the user clicks the <code>more</code> button. (Now the total records should be 20 - (previous 10 + the 10 records as a result of clicking the <code>more</code> button ))</p> <p>NOTE: I will be downloading all 100 records and saving it in <code>self.arrayThatContainsAllHundredRecords</code> in the <code>viewDidLoad</code> method.</p> <p>I believe that i have to make some change before executing <code>[self.tableView reloadData];</code>, as in tell to load 10 records.</p> <p>Well, say if i only had 53 records. Then the user will click the more button 5 times and on the 6th instance, the table should display only 3 records. How can this be handled in the tableview:numberOfRowsInSection: ?</p>

    1. COWait, so when the first 10 rows are visible and the user presses the button to show more records, what is visible at that point? The first 20 records, or only records 11-20? In my answer I assumed the former, and MusiGenesis is responding for the latter.

    2. COThe 1st 10 records + the 2nd 10 records should be visible. There should be a total of 20 records now

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
