Dynamic Table view data source - iphone

Question

Hi I am doing a app in which i use a Dynamic view table, Bit i have a problem with NSManged Objects, can any one find out whats going wrong.
find the code below for your reference.
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return ([self.controlSelections count]);
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"plainCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
id controlOption = [self.controlSelections objectAtIndex:indexPath.row];
NSString *option = nil;
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
if ([controlOption isKindOfClass:[NSString class]])
{
option = (NSString *)controlOption;
cell.textLabel.text = option;
}
else if ([controlOption isKindOfClass:[NSDictionary class]])
{
NSDictionary *optionDict = (NSDictionary *)controlOption;
option = [optionDict valueForKey:self.listKey];
cell.textLabel.text = option;
}
else if ([controlOption isKindOfClass:[NSManagedObject class]])
{
NSManagedObject *context=[self NSManagedObject];
NSManagedObject *optionData = (NSManagedObject *)controlOption;
option = [optionData valueForKey:self.listKey];
cell.textLabel.text = option;
}
return cell;
}
the problem is in the following code it is not taking NSMangedObject:
else if ([controlOption isKindOfClass:[NSManagedObject class]])
{
NSManagedObject *context=[self NSManagedObject];
NSManagedObject *optionData = (NSManagedObject *)controlOption;
option = [optionData valueForKey:self.listKey];
cell.textLabel.text = option;
}
any help will be appreciated. thanks in advance.

Try something on these lines -
else if ([controlOption isKindOfClass:[NSManagedObject class]])
{
NSManagedObjectContext *context=[self managedObjectContext]; //I guess you have MOC somewhere.
NSEntityDescription *entityDesc = [NSEntityDescription entityForName:[optionData valueForKey:self.listKey] inManagedObjectContext: context];
NSFetchRequest *request = [[NSFetchRequest alloc] init];
[request setEntity:entityDesc];
NSError *error;
NSArray *objects = [context executeFetchRequest:request error:&error];
cell.textLabel.text = [objects objectAtIndex:0]; //for eg
}
