i have a UITableView that is being populated by core data , now , when i click on a cell , it pushes me to another view where i can edit the data that is in that particular index , when i return , the system either crashes or else doesnt load the changes onto the labels , any ideas ? code below

-(void)viewWillAppear:(BOOL)animated {    
searchCriteria = [[NSMutableString alloc] initWithString:@"clientName"];
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"clientName" ascending:YES];
NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil];
[fetchRequest setSortDescriptors:sortDescriptors];
NSEntityDescription *entity = [NSEntityDescription entityForName:@"Client" inManagedObjectContext:managedObjectContext];
[fetchRequest setEntity:entity];    
fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:nil cacheName:@"Root"];

[self.clientTableView reloadData];
[super viewWillAppear:animated];    
}

and

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {

    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

}

Client * client = [self.fetchedResultsController objectAtIndexPath:indexPath];
clientNameLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 250.00, 30.0)];
clientNameLabel.tag = 1;
clientNameLabel.backgroundColor = [UIColor clearColor];

The Crash Logs are as follows :

And some other code you might find useful are :

 - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
 {
   return 1;
 }

 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
 {
   return [fetchedObjects count];
 }


 - (float)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
   {
    return 70.0;
   }
