Question

I tried this but getting an exception error at cellforrowatindexpath

Below is the exception I got.

Assertion failure in -[UITableView _createPreparedCellForGlobalRow:withIndexPath:], /SourceCache/UIKit_Sim/UIKit-1914.84

if(aTableView==specTable)
{
    static NSString *CellIdentifier = @"cell";
    UITableViewCell *cell = [specTable dequeueReusableCellWithIdentifier:CellIdentifier];
    if(cell==nil)
    {
        cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2
                                    reuseIdentifier:CellIdentifier];

    }

    return cell;

} 
else 
{    
    static NSString *CellIdentifier2 = @"cell2";
    UITableViewCell *cell= [table2     dequeueReusableCellWithIdentifier:ReviewCellIdentifier2];
}

return cell;

Answer 1

Two problems:

1. You never return cell2. At the end of this method, you always return cell, regardless of whether the sender table view was equal to the first or second one.
2. You don’t create the cell as you do in the first part if in the second part (the else branch) the dequeueReusableCellWithIdentifier: message returns nil.

All in all:

if (aTableView == specTable)
{
    static NSString *cellIdentifier = @"cell";
    UITableViewCell *cell = [specTable dequeueReusableCellWithIdentifier:cellIdentifier];
    if (cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2
                                    reuseIdentifier:CellIdentifier] autorelease]; // you were also leaking memory here

    }

    return cell;

} 
else 
{    
    static NSString *cellIdentifier2 = @"cell2";
    UITableViewCell *cell2 = [table2 dequeueReusableCellWithIdentifier:cellIdentifier2];
    if (cell2 == nil)
    {
        cell2 = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2
                                    reuseIdentifier:CellIdentifier] autorelease];

    }
    return cell2;
}

return nil; // just to make the compiler happy
