Can any one give me the code for the expansion and contraction of the table view cell to display the text of a particular cell in iphone.
If you want variable heights for your table cells you will need to look into:
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;
But your question isn't clear enough to know for sure what you at trying to do.

I tried to insert the background image using following code:
Pic = "C://Picture/Logo1"
Activesheet.SetBackgroundPicture Pic
This inserts the picture to full sheet but I want to add it to particular cell or a range of cells. Please help
As far as I know excel doesn't support appending the image to a cell (with or without VBA).
The background of a single cell supports colors/gradients/fill-patters, but not the pictures.
It is possible however, to "place" the picture (shape) object with the same width and height right above the cell and make it locked and move around together with the cell if somebody attempts to resize cell widths. I personally wouldn't go that way, too much to code and too much risk of breaking the structure.
If you create a Table in Excel all columns get an autofilter.The Button is always shown on the right of the columnheader:
My Table has ~60 Columns. To safe horizontal space i would like to move the Button on top/below the cell:
Does anybody know how to move a autofilterbutton on top of a cell?
Add a space on the cell above.
I create my table cell once, as its a slow process due to all the images on the cell.
Its very rare anything changes, but there is a rare case where I want to the cells completely.
The code that gets a cell is
UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:PlaceholderCellIdentifier];
if there is no associated cell I create one.
UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:PlaceholderCellIdentifier];
if (cell == nil)
{
//create cell
return cell;
}
else
{
return cell;
}
Is there a way to dump all of the reusable cells that are associated with this table? So when I call
[table reloadData];
It will generate a fresh set of cells?
Many Thanks,

According to this answer you can. However I strongly advice against this. It is bad practice to meddle with class internals.
Apart from that I don't see why you would want to do this. The reusing of cells is there to actually speed up the process and to keep down used memory. I don't see how creating a cell from scratch could actually be quicker than reusing one.
Just reuse the existing cells. There is no need for deallocating the existing ones.
I guess that you wanted to ask the question differently. You may wanted to ask how to enforce the table view to re-display every cell with updated data ... ? If so then the answer is to use call
[self.tableView reloadData];
(assuming that you place the call within the table view controller)
I've got a UITableView filled with UITableViewCells.
Now when I scroll down, there's a problem with the two bottom cells. The last cell shows up as the third from the bottom and there are two additional cells below which shouldn't be there.
What are possible causes of such a behavior?
Editor's note: I hope I correctly interpreted the question. The problem could also be that the last two cells don't show up at all.
The number of cells in the table view stems from the delegate method numberOfRowsInSection:. Check what number is being set here, if you're counting an array then NSLog the count ([MyArray count]) and check to see if its as you expect. Its the only thing I can think of that would lead to additional or missing cells in your tableview without source code
So, I was wondering what is the best way to make it so that the first cell is custom cell and the others are normal cells. In the past I have only made tableViews with all cells the same. Thanks!
In -tableView:cellForRowAtIndexPath: of your data source, you can return any kind of cell you like. So you should just check the index path and return a different cell for the first cell.
