Cell configuration method - xcode

Question

Am having some trouble configuring table cell in an array. Have commented out the errors returned by the LLVM compiler.
Implementation file:
#import "BIDFirstLevelController.h"
#import "BIDSecondLevelViewController.h"
#implementation BIDFirstLevelController
#synthesize controllers;
- (void) viewDidLoad
{
[super viewDidLoad];
self.title = #"First Level";
NSMutableArray *array = [[NSMutableArray alloc]init];
self.controllers = array;
}
- (void) viewDidUnload
{
[super viewDidUnload];
self.controllers = nil;
}
#pragma mark -
#pragma mark Table Data Source Methods
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self.controllers count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *FirstLevelCell = #"FirstLevelCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:FirstLevelCell];
if (cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault reuseIdentifier:FirstLevelCell];
}
}
// Configure the cell
NSUInteger row = [indexPath row]; // replace with NSUIndexPath
BIDSecondLevelViewController *controller = [controllers objectAtIndex:row]; //replace controllers with controller
cell.textLabel.text = controller.title; // unknown type name 'cell', Expected identifier or '('
cell.imageView.image = controller.rowImage; // Expected identifier or '(
cell.accessoryType = UITableViewAccessoryDisclosureIndicator; // Unknown type name 'cell'
return cell;
}
#pragma mark -
#pragma mark Table View Delegate Methods
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{NSUInteger row = [indexPath row];
BIDSecondLevelViewController *nextController = [self.controllers objectAtIndex:row];
[self.navigationController pushViewController:nextController animated:YES];
#end
Interface file:
#import <UIKit/UIKit.h>
#interface BIDFirstLevelController : UITableViewController
#property (strong, nonatomic) NSArray *controllers;
#end // Unexpected '#' in program

You need to delete a curly brace after your if statement your tableView:cellForRowAtIndexPath: should look like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *FirstLevelCell = #"FirstLevelCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:FirstLevelCell];
if (cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault reuseIdentifier:FirstLevelCell];
}
// DELETE THE } THAT IS HERE
// Configure the cell
NSUInteger row = [indexPath row];
BIDSecondLevelViewController *controller = [controllers objectAtIndex:row];
cell.textLabel.text = controller.title;
cell.imageView.image = controller.rowImage;
cell.accessoryType = UITableViewAccessoryDisclosureIndicator;
return cell;
}
You also need to add a curly brace to close your final function:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSUInteger row = [indexPath row];
BIDSecondLevelViewController *nextController = [self.controllers objectAtIndex:row];
[self.navigationController pushViewController:nextController animated:YES];
} // This curly brace is missing
#end
