how to hide empty rows in a UITableView and change the height of the Uitableview based on non-empty rows

Question

I have couple of problems with my UITableView.

1. When I add a UITableview on my page, by default it brings up some fixed number of rows,

Answer 1

[self.SomeTableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];

Use this to get rid of the lines if the UITableView is empty.

Answer 2

A bit hidden in Bourne's answer; if you want to hide to bottom empty rows in a plain tableview with multiple sections, use this answer:

Answer 3

You sure you are using UITableViewStyleGrouped style?

Because by default it is set to UITableViewStylePlain which shows empty cells too after displaying filled cells.

Answer 4

in the method that returns the number of rows, specify the count yourself dynamically. For example if you are going to populate the table with say a NSArray named arrayForRows:

return [arrayForRows count]; // inside the method which returns the number of rows.

The above is a simple example populating a table with an array as a datasource. There are no empty rows. Only that many rows show up in the table according to the count of items in the array populating the table.

I think you mean height of the row in the table. You can play around with the height of the rows by using the method:

(CGFloat)tableView:(UITableView  *)tableView heightForRowAtIndexPath:(NSIndexPath  *)indexPath

EDIT: ah now I get what you are trying to achieve. You are trying to avoid showing the empty rows separated with those separator lines right? See this post:

This can also be done through Interface Builder. Simply add a 1 pixel tall UIView as a footer to the UITableView. It's essentially the same as most of the answers here, but it keeps some UI specifics in the view instead of in the view controller.
