UITableView custom cells always change there content - must stop it - iphone

Question

i have a UITableView with custom cells (code below) that load the data from NSDictionary (the NSDictionary loads there data from NSArray objectatIndexPath:indexpath.row.
Now, i have a DidSelectRow functions that works in the same way (NSArray -> NSDictionary -> Cell data).
the problem is that when im scrolling my table its change my cells contant.
i must have my cells always reload that same order. and i must stop this reloading data when scrolling.
This is the code im using to load my table view and load data to table view cells and my didSelectRow: Please help, i dont have time for this problem...

Answer 1

I am not sure I understand your problem completely but I do see an error in the way you build the cells. After dequeueing the cell, you should only init the cell if it's nil NOT init and build the cell.
static NSString *SimpleTableIdentifier = #"SimpleTableIdentifier";
UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier];
if(cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:SimpleTableIdentifier];
}
// Now build the cell.
If you don't rebuild the cell every time, it will just reuse the cell that was originally built.

Answer 2

your problem is that everything is with in this:
if(cell == nil) {
//Your Code
}
What is happening is the tableview reuses cells. You are only changing the content if(cell == nil).
What you need is to only create a new cell in side if(cell == nil)
and move the rest of your code out of that if statement
