How to set different images for every cell in uiTableView.?

I have tableView and i want to set the different image for every cell in my tableView based of certain condition but i am getting the image of last satisfied condition for all cells.

here is my code:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];

    }

    cell.textLabel.font = [UIFont boldSystemFontOfSize:14]; 
    cell.textLabel.numberOfLines = 2; 

if (self.pickerSelectedRow == [self.datePickerArray objectAtIndex:1])
    {
        for (int i=0; i<[appDelegate.serverResponseArray count]; i++)
        {
            if([[[appDelegate.serverResponseArray objectAtIndex:i]valueForKey:@"session_type" ] isEqual: @"workshop"])
            {
                cell.imageView.image = [UIImage imageNamed:@"workshops.png"];
            }
            if([[[appDelegate.serverResponseArray objectAtIndex:i]valueForKey:@"session_type" ] isEqual: @"keynote"])
            {
                cell.imageView.image = [UIImage imageNamed:@"keynote.png"];
            }
            if([[[appDelegate.serverResponseArray objectAtIndex:i]valueForKey:@"session_type" ] isEqual: @"panel"]|| [[[appDelegate.serverResponseArray objectAtIndex:i]valueForKey:@"session_topic" ] isEqual: @"WISNET"])
            {
                cell.imageView.image = [UIImage imageNamed:@"pannel.png"];
            }
            if([[[appDelegate.serverResponseArray objectAtIndex:i]valueForKey:@"session_type" ] isEqual: @"social"] || [[[appDelegate.serverResponseArray objectAtIndex:i]valueForKey:@"session_topic" ] isEqual: @"RWW"])
            {
                cell.imageView.image = [UIImage imageNamed:@"social.png"];
            }


        }
       cell.textLabel.text =  [[self.globalSessionArray objectAtIndex:indexPath.section] objectAtIndex:indexPath.row];
    }

Expected output: i am expecting output something like this (ignore the content of cells.)

output i am getting:

Fill your UITableViewCell content in tableView:willDisplayCell:forRowAtIndexPath: method. And to compare 2 NSString use isEqualToString: method.

EDIT:

- (void)tableView:(UITableView*)tableView willDisplayCell:(UITableViewCell*)cell forRowAtIndexPath:(NSIndexPath*)indexPath
{
    cell.textLabel.font = [UIFont boldSystemFontOfSize:14]; 
    cell.textLabel.numberOfLines = 2;
    if (self.pickerSelectedRow == [self.datePickerArray objectAtIndex:1])
    {
        for (int i=0; i<[appDelegate.serverResponseArray count]; i++)
        {
            NSString* session_type = [[appDelegate.serverResponseArray objectAtIndex:i]valueForKey:@"session_type"];
        if([seesion_type isEqualToString: @"workshop"])
            cell.imageView.image = [UIImage imageNamed:@"workshops.png"];
        else if([session_type isEqualToString: @"keynote"])
            cell.imageView.image = [UIImage imageNamed:@"keynote.png"];
        else if([session_type isEqualToString: @"panel"]|| [[[appDelegate.serverResponseArray objectAtIndex:i]valueForKey:@"session_topic" ] isEqualToString: @"WISNET"])
            cell.imageView.image = [UIImage imageNamed:@"pannel.png"];
        else if([session_type isEqualToString: @"social"] || [[[appDelegate.serverResponseArray objectAtIndex:i]valueForKey:@"session_topic" ] isEqual: @"RWW"])
            cell.imageView.image = [UIImage imageNamed:@"social.png"];
    }
    cell.textLabel.text =  [[self.globalSessionArray objectAtIndex:indexPath.section] objectAtIndex:indexPath.row];
}

Are you sure if (self.pickerSelectedRow == [self.datePickerArray objectAtIndex:1]) is satisfied every time?

Also why are you comparing value [self.datePickerArray objectAtIndex:1] with self.pickerSelectedRow value?

replace isEqual: by isEqualToString:

in your code it will always return i = 0;

maybe you can try something like:

       if([[[appDelegate.serverResponseArray objectAtIndex:indexPath.row]valueForKey:@"session_type" ] isEqualToString: @"workshop"])
        {
            cell.imageView.image = [UIImage imageNamed:@"workshops.png"];
        }
        if([[[appDelegate.serverResponseArray objectAtIndex:indexPath.row]valueForKey:@"session_type" ] isEqualToString: @"keynote"])
        {
            cell.imageView.image = [UIImage imageNamed:@"keynote.png"];
        }
        if([[[appDelegate.serverResponseArray objectAtIndex:indexPath.row]valueForKey:@"session_type" ] isEqualToString: @"panel"]|| [[[appDelegate.serverResponseArray objectAtIndex:indexPath.row]valueForKey:@"session_topic" ] isEqualToString: @"WISNET"])
        {
            cell.imageView.image = [UIImage imageNamed:@"pannel.png"];
        }
        if([[[appDelegate.serverResponseArray objectAtIndex:indexPath.row]valueForKey:@"session_type" ] isEqualToString: @"social"] || [[[appDelegate.serverResponseArray objectAtIndex:indexPath.row]valueForKey:@"session_topic" ] isEqualToString: @"RWW"])
        {
            cell.imageView.image = [UIImage imageNamed:@"social.png"];
        }

Use isEqualToString: for string comparison
