hey all i have a program for inserting new now dynamically in table view. But it displays the inserted row the end.How can i display the inserted row at the first position.
Usually, I will have an array to keep the data and each cell in the table view will correspond to an element in an array. If you have a NSMutableArray and you add the element at the beginning of the array and reload data, it should work properly. Or you can create a new array and add the new element at the first element and copy all old elements into the new one

I am working in an app in which I have an array and using that array that comes as response from JSON in the table view .Now In table view I want Sections in which i get the value from the array Alphabetically.For say if the Array element starts with A then it should go on A section and similar for all other alphabets from A to Z. How can i do this?
I have a UITableView where I can add a new item with a touch of a button. I would like to highlight this newly added item. Since UITableView is data-driven and cells are recycled, the only way I can think of so far to mark this newly added item is to add a BOOL flag in the data itself, then highlight the cell and negate the flag on first encounter.
Is there another way of doing this without having to contaminate the data source?
My first thoughts..
Create an Integer [myObjectArray count];
When you add the new object you can reload table
Create a new integer [myObjectArray count];
Compare the two integers when table reloads. If the 1st int is less than the new int
then you obviously have added another object.
When creating cell check if the cell indexpath.row is equal to the last object count in your array, if it is then you can fill the cell background with another color.
Hope that makes sense?
Assuming your data is ordered and indexable, use another NSArray (or NSMutableArray) of NSIndexPath to maintain a list of newly added data. If you only have one section, then you could substitute NSNumber for NSIndexPath and just record the rows.
I have looked at several forums and read different threads, but I can't seem to find an answer. I'd really like some help. I have an array that stores Labels whose contents I display in the UITableView's row. The second row contains fresh data added to the same array and so on. My question is, everytime the labels are displayed in the UITableView, I want it to be displayed on the top row. In essence, the older ones keeps shifting one row down. I understand I need to use: "tableView:moveRowAtIndexPath:toIndexPath:" but it only seems to work with arrays whose contents are strings.
Just to clarify, I'm not displaying each element of the array on a new line. I'm displaying all the elements of the array on a single row, then changing the elements and displaying that as the next row. Except I want the second row to be above the first and so on.
The array you're using is an ordered collection of object, so the easiest way to perform what you're looking fro would be to add the new object in the first position of your array. You can achieve that using the method insertObject:atIndex: of NSMutableArray
ex:
[myArray insertObject:newObject atIndex:0];
This way you don't have to worry about moving your tableView cells ordering.
Hope this helps,

First of all you don't need to keep the label in some array, you can keep only the string. And when add an new object to the array add it on position 0 and the do and reload of table view.
I am trying to update a cell table at run time, the cell table gets its date from a list
Cell_Table.setRowData(0,AllMessages);
I am trying to update the List AllMessages then do this Cell_Table.redraw(); with no success.
I am trying this do this again Cell_Table.setRowData(0,AllMessages); with no success AS WELL
when I am using the same technique to add rows, everything is ok but when i am removing some data from the list feeding it, the cell table is not being updated!

# GWT Discussion
setRowData(int, List) replaces the range of data. So, if the list gets
shorted, it doesn't touch the items that appear after the end of the list.
You have to update the row count as well:
table.setRowData(0, NewMessages);
table.setRowCount(NewMessages.size(), true);
Or, you can use the new version of setRowData that does not take a start
index (since GWT 2.1.1):
table.setRowData(NewMessages);
I have UITableView which has edit button in all rows with tag as id of the data in corresponding row.In the first row i have button to insert new item when i click on button on first row to add new item,navigates to insert form,add data to database in that forms n bring back to original uitableview which i reload in viewDidAppear.New Item along with button can be seen in the table n also i can view (in my logs ofcourse ) my NSMutableArray get updated with new data n button with appropriate tag (i.e with new ID) ;which i have provided as data source to uitableview; while binding data.
Now But when i tried to edit my newly added item i got correct ID for my Data at the button tag which is clicked, but surprisingly ,now , same array which i have observed being updated while binding,has short of new data in array but surprisngly visible on uitableview
y is it so ????
Have you already tried [yourTable reloadData]; ?
