. We all need to start somewhere.
I can send in some code if it helps
What I need to know before I do this is where the problem is likely to be: in the ViewController that cannot go back, or the original ViewController?
@implementation UserNameViewController
@synthesize detailItem;
@synthesize tableView;
- (id)init
{
if (self = [super init]) {
self.title = @"Accounts";
}
return self;
}

{
tableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain];
tableView.delegate = self;
tableView.dataSource = self;
tableView.separatorStyle = UITableViewCellSeparatorStyleSingleLine;
self.view = tableView;
}
- (void)dealloc
{
tableView.dataSource = nil;
tableView.delegate = nil;
[passwordViewController release];
[tableView release];
[super dealloc];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [[detailItem objectForKey:@"accounts"] count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath withAvailableCell:(UITableViewCell *)availableCell {
UISimpleTableViewCell *cell = nil;
if (availableCell != nil) {
cell = (UISimpleTableViewCell *)availableCell;
} else {
cell = [[[UISimpleTableViewCell alloc] init] autorelease];
}
// Set the value in the cell
NSArray *usernames = (NSArray *)[detailItem objectForKey:@"accounts"];
NSDictionary *account = (NSDictionary *)[usernames objectAtIndex:indexPath.row];
cell.text = [account objectForKey:@"username"];
return cell;
}
- (void)tableView:(UITableView *)tableView selectionDidChangeToIndexPath:(NSIndexPath *)newIndexPath fromIndexPath:(NSIndexPath *)oldIndexPath {
if (passwordViewController == nil) {
passwordViewController = [[PasswordViewController alloc] init];
}
// Set the detail controller's inspected item to the currently-selected item
passwordViewController.detailItem = [[detailItem objectForKey:@"accounts"] objectAtIndex:newIndexPath.row];
[[self navigationController] pushViewController:passwordViewController animated:YES];
