[self.countryList reloadRowsAtIndexPaths:[NSArray arrayWithObjects:[NSIndexPath indexPathForRow:6 inSection:0], nil] withRowAnimation:UITableViewRowAnimationNone]; // or NO ;)
My problem is that I have a tableview with 10+ items with only 6 cells in view, but when the data is loaded and the table is scrolled cell 7 has no data in it. How can I reload the data in that 1 cell?
The code above is what I am using and it doesn't work!
---EDIT---
if (cell == nil) {
cell =[[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:identifier]autorelease];
//[cell setBackgroundColor: [UIColor clearColor]];
mainLabel = [[[UILabel alloc] initWithFrame:CGRectMake(52.0, 0.0, 200.0, 20.0)] autorelease];
mainLabel.tag = 1;
mainLabel.font = [UIFont systemFontOfSize:14.0];
mainLabel.textAlignment = UITextAlignmentLeft;
mainLabel.textColor = [UIColor blackColor];
mainLabel.opaque = YES;
mainLabel.backgroundColor=[UIColor clearColor];
[cell.contentView addSubview:mainLabel];
revenue = [[[UILabel alloc] initWithFrame:CGRectMake(52.0, 20.0, 150.0, 20.0)] autorelease];
revenue.tag = 3;
revenue.font = [UIFont systemFontOfSize:14.0];
revenue.textAlignment = UITextAlignmentLeft;
revenue.textColor = [UIColor blackColor];
revenue.opaque = YES;
revenue.backgroundColor=[UIColor clearColor];
[cell.contentView addSubview:revenue];
promos = [[[UILabel alloc] initWithFrame:CGRectMake(252.0, 20.0, 150.0, 20.0)] autorelease];

promos.textColor = [UIColor blackColor];

promos.backgroundColor=[UIColor clearColor];
[cell.contentView addSubview:promos];

updates.tag = 5;

[self performSelectorInBackground:@selector(loadImageInBackground:) withObject:arr];
[arr release];

This is typically a misuse in the recycle/reuse mechanism of cellForRowAtIndexPath:
.
Cells are reused when you scroll to avoid allocating too much UITableViewCells. So you need to set the content of the cell in cellForRowAtIndexPath:
in both case, either if the cell just have been allocated (cell==nil) or if the cell has been reused (cell!=nil).
