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

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:
