macOS [iPhone] UITableView strangeness

[typewriter]

Hello -

I'm writing some code for the iPhone, and have implimented a UITableView.
I have created a delegate and a dataSource. There is a strange issue however- When the table is displayed, the dataSource knows the correct *number* of cells to return, but returns duplicate copies of the 0th cell for all cells. Its behaving as if [UITableview reloadData] keeps asking cellForRowAtIndexPath for index 0.

Also, when clicking (tapping) on the cells, didSelectRowAtIndexPath only returns 0 for the tapped index.

Is this related to reuseIdentifier?

In my dataSource:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{
	
	// Returns a formatted Table Cell
	int index=[indexPath indexAtPosition:0] ;
	printf("Creating cell for index %d\r\n",index);  //Always prints 0!

In my delegate:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

	printf("Index of tapped item: %d\r\n", [indexPath indexAtPosition:0]);  //Always prints 0
	
}

Thank you in advance for any help !!

Use indexPath.row. This will get you the results you want.

Ahh! That solved the problem! Thank you! The weird thing is that I swear that using indexAtPosition that way *used* to work.

This was a very simple answer - if only the docs had some mention of it!

The row property doesn't show up in the docs (online or local) for NSIndexPath, and it doesn't inherit that from NSObject..

It's a category for NSIndexPath provided by UIKit. It should be listed as NSIndexPath(UITableView). If you search the iPhone API for NSIndexPath, it should be one of two or three results.
