Add rows to existing UITableView section

Question

I am trying to get some sample code on how I would add rows to an existing UITableView. I am trying to use the insertRowsAtIndexPaths: function.

Answer 1

You need to handle these functions if you are gonna insert row and section in a table view.

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return noOfSections;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [[noOfRows objectForIndex:section] intValue];
}

also if you are updating your table view it is recommended that you use beginUpdates and endUpdates method.

this is how you insert new row and section.

noOfSections++;
[self.tableView insertSections:[NSIndexSet indexSetWithIndex:3] withRowAnimation:UITableViewRowAnimationTop];


// update your array before calling insertRowsAtIndexPaths: method
[self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:1 inSection:2]] 
                      withRowAnimation:UITableViewRowAnimationTop];

check the sample code provided by the apple.
