Calculate the table's contentSize.height with custom cells of different types iphone

Question

Hi all,

In my application , the tableview is having different types of custom cells with different heights. I want to put a view below this tableView, for which I need to calculate the table contentView height, how can I do it?

Earlier I used to do it like: (noOfRows * cell_height), but that was for static heights.

Thanx in advance.

Answer 1

a slightly ugly way..but should work..

tableView.backgroundView.frame.size.height

Answer 2

The easiest thing I can think of would be to set your view as the table's tableFooterView

Answer 3

I think what you're looking for is self.view.bounds.size.height.

Check out Oliver Drobnik's detailed post on creating a pull-to-reload table view. In his case it's easier, because the view is at the top, so he checks for a negative contentOffset.

If you want it at the bottom, you could check for scrollView.contentOffset.y > (self.view.bounds.size.height + pullToReloadViewHeight)

Answer 4

If you've implemented your own custom cells, then you've probably already implemented this function in your table delegate:

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

Just iterate through your rows, calling this function for each one, and sum up the result.
