Answer 1

Have you allocated your cell with an instance of UITableViewCell ?

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:reusableCell];

or

cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reusableCell] autorelease];

Answer 2

Try by changing

NSString *cellValue =[NSString stringWithFormat:@"%@",[arrTrimmedTblData objectAtIndex:indexPath.row]];

Answer 3

replaceOccurrencesOfString method return NSString object. So, you have to store return string in another string variable.

Answer 4

 NSString *cellValue = [[arrTrimmedTblData objectAtIndex:indexPath.row] retain];
 crashing Due To That Object is Not Available.
 I Hope It Will Work...

Cheers
