How to Set the First Value to Table to Colour

Question

I have sorted an Array in Ascending order. I need to display the first value of the table to be colored. How can I do this

My code is :

NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"isDefault"  ascending:NO];
sortedArray = [beneficiariesArray sortedArrayUsingDescriptors:[NSArray arrayWithObject:descriptor]];
NSLog(@"This is Sorted Array %@",sortedArray);


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

{
    static NSString *simpleTableIdentifier = @"SimpleTableItem";    
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];    
    if (cell == nil)
    {    
      cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];    
      cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    }
    cell.textLabel.text = [[sortedArray objectAtIndex:indexPath.row] objectForKey:@"Fullname"];
    return cell;
}

Here it try it in cellForRowAtIndexPath
if(indexPath.row == row number)
{
cell.backGroundColor = [UIColor anycolor]; // set color as you want.
}

in row number provide the value where you want the color to be displayed and in anycolor type the colorname available.

At cellForRowAtIndexPath Method. To set color for the first value .

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

{

static NSString *simpleTableIdentifier = @"SimpleTableItem";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

if (cell == nil)

{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];

cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

}
if(indexPath.row==0)
{
cell.textLabel.textColor=[UIColor greenColor];
// or you can set background as cell.backgroundColor=[UIColor blackColor];
}
cell.textLabel.text = [[sortedArray objectAtIndex:indexPath.row] objectForKey:@"Fullname"]; return cell;
 }

    }else{

        // normal stuff

        cell.textLabel.textColor = [UIColor blackColor];

    cell.textLabel.text = [[sortedArray objectAtIndex:indexPath.row] objectForKey:@"Fullname"];

    return cell;

Make sure you have connected your table view delegate and datasource.
In your cellForRowAtIndexPath use this.

if(indexPath.row==0)

cell.textLabel.textColor=[UIColor redColor];

There is a property for visible cells.

so you can set the color of the first cell always.

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

{
    static NSString *simpleTableIdentifier = @"SimpleTableItem";    
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];    
    if (cell == nil)
    {    
      cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];    
      cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    }

    [[tableView.visibleCells objectAtIndex:0] setBackgroundColor:[UIColor redColor]]; //This line changes color for first visible cell
    [[tableView.visibleCells objectAtIndex:1] setBackgroundColor:[UIColor clearColor]]; //This line clears the color of second cell if scrolling in upward direction.

    cell.textLabel.text = [[sortedArray objectAtIndex:indexPath.row] objectForKey:@"Fullname"];

    return cell;
}

you can set it by use of indexPath.row in cellForRowAtIndexPath: method.

Replace with following code :

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

{
    static NSString *simpleTableIdentifier = @"SimpleTableItem";    
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];    
    if (cell == nil)
    {    
      cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];    
      cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    }

    if(indexPath.row == 0)
     cell.textLabel.textColor = [UIColor redColor]; // set color as you want.

    cell.textLabel.text = [[sortedArray objectAtIndex:indexPath.row] objectForKey:@"Fullname"];

    return cell;
}

@VMC501 - which value ?? and also tableView is scrollable hope you know about it. – iPatel Mar 19 '14 at 06:46
the first values disapprears . it looks fine when i dont scroll – iOSDeveloper Mar 19 '14 at 06:48
Mate first read [UITableView](https://developer.apple.com/library/ios/documentation/uikit/reference/UITableView_Class/Reference/Reference.html), It is default behavior of it. – iPatel Mar 19 '14 at 06:51
is there any solution for it ? – iOSDeveloper Mar 19 '14 at 06:53
@patel. i know its scrollable. when i scroll down, and go to the top again. the text in the first row is empty – iOSDeveloper Mar 19 '14 at 06:57
Set `NSString *simpleTableIdentifier = [NSString stringWithFormat:@"S%1dR%1d", indexPath.section, indexPath.row]` – iPatel Mar 19 '14 at 07:00

You need to simply check the cell Index value like this :

if (indexPath.row == 0)
{
     // Place your logic
}
