Add fixed row in a table view

alexgiul · 01-03-2010, 08:12 AM

Hi all!

I would know if it's possible and how add a fixed row in a table as last row.

I try to explain better: I have an array, dynically loaded, and I want to show the "+" sign when I enable the table editing i a row named "Add New item".

I think I should manage into method "cellForRowAtIndexPath" but I don't what I should do

Thanks a lot

1. In -

Code:

(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

method add one to current value in ex. if you have
return [dataArray count] change it to return [dataArray count]+1;

2. In -

Code:

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

when indexPath.row < [dataArray count] put your normal code and when

indexPath.row = [dataArray count] add code like here:

Code:

cell.text = "Add New item";

3. In -

Code:

(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {

add code like here:

Code:

        if (indexPath.row == [dataArray count]) {
            style = UITableViewCellEditingStyleInsert;
        }

Thanks a lot,

with your tips I get it working as expected, but I have a question:
in the way you tell m, I have always "Add New Item" on the list, so I decided to put a code like the following :

Code:

if(self.editing) cell.text = "Add New item";

in this way I thought to show the msg "Add new Item" with green plus sign only when I'm in edinting mode, but in the simulator the msg disappear.

Where am I wrong?

In numberOfRowsInSection put code like here

Code:

            
NSInteger rows = [dataArray count];
if (self.editing) {
    rows++;
}
return rows

and don't manipulate with self.editing in cellForRowAtIndexPath
look into iPhoneCoreDataRecipes in AppleDocs - this is good example.

it doesn't work, I follow in debug and the application calls "numberOfRowsInSection" only at the starting point and not when I click on edit button..maybe should I refresh the content of table?
