Auto Increment to each cell in different section table - ios

Question

I want to set a number to each cell in the table view, and i have diffent section so can't use indexPath.row.
Currently im using one variable count and increasing it in cellForRowAtIndexPath count++.
but it refresh when im scrolling table.
SO how to set auto increament number to each cell.

Answer 1

Try this on cellForRowAtIndexPath.. Will calculate previous sections and its row and adds with current row
NSInteger cellNumber = indexPath.row;
for (int i =0; i<indexPath.section; i++) {
cellNumber += [tableView numberOfRowsInSection:i];
}

Answer 2

The instance variable won't work. Your index should be calculable, as your problem states, from the indexPath (row and section), lacally within cellForRowAtIndexPath.
Try this:
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"identifier"];
NSInteger count = 0;
for (NSInteger sec=0; sec < indexPath.section; sec++) {
NSInteger rows = [tableView numberOfRowsInSection:sec];
count += rows;
}
count += indexPath.row + 1;
NSLog(#"Current row is: %ld", (long)count);
return cell;
}

Answer 3

copy and paste the code:-
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell"];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1
reuseIdentifier:#"Cell"];
}
// Configure the cell...
NSInteger cellNumber = indexPath.row;
for (int i =0; i<indexPath.section; i++) {
cellNumber += [tableView numberOfRowsInSection:i];
}
cell.textLabel.text = [NSString stringWithFormat:#"%ld", (long)cellNumber];
return cell;
}

Answer 4

Try a combination of
NSString *string = [NSString stringWithFormat:#"%#%#",#(indexPath.section),#(indexPath.row)];
cell.tag = [string intValue];
You'll always get a unique number that you can use for reference.
