    copied!<p>I'm creating a simple app that stores data into a sqlite database and retrieves data from it. I'm able to store data and I'm also able to populate a UITableView with all the data, showing a field (name) in the prototype cell. What I'm trying to do now is to open a view on tap to show ALL the details. So I did set up a viewController with 3 fields to be filled in, but I don't know how to transfer data between that cell to the new view. </p> <p>Here's my code:</p> <pre><code>#import "RootViewController.h" #import "AppDelegate.h" #import "Inserimento_Esame.h" #import "Dettagli_Esame.h" @interface RootViewController () @end @implementation RootViewController @synthesize nome,crediti,voto; - (id)initWithStyle:(UITableViewStyle)style { self = [super initWithStyle:style]; if (self) { // Custom initialization } return self; } - (void)viewDidLoad { [super viewDidLoad]; NSString *docsDir; NSArray *dirPaths; dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); docsDir = [dirPaths objectAtIndex:0]; databasePath = [[NSString alloc] initWithString: [docsDir stringByAppendingPathComponent: @"Esami.sqlite"]]; dataList = [[Data alloc] init:databasePath]; } - (void)viewDidUnload { [super viewDidUnload]; // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation {return YES;} #pragma mark - Table view data source - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { // Return the number of sections. return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { // Return the number of rows in the section. return [dataList getSize]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; } NSDictionary *itemAtIndex = (NSDictionary *)[dataList objectAtIndex:indexPath.row]; cell.textLabel.textColor = [UIColor whiteColor]; cell.textLabel.text = [itemAtIndex objectForKey:@"nome"]; cell.detailTextLabel.textColor = [UIColor whiteColor]; cell.detailTextLabel.text = [itemAtIndex objectForKey:@"voto"]; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [self performSegueWithIdentifier:@"DETTAGLI" sender:indexPath]; } - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { if ([[segue identifier] isEqualToString:@"DETTAGLI"]) { NSLog(@"Dettagli"); Dettagli_Esame *destination = [segue destinationViewController]; NSIndexPath * myIndexPath = [self.tableView indexPathForSelectedRow]; NSDictionary *itemAtIndex = (NSDictionary *)[dataList objectAtIndex:myIndexPath.row]; destination.Dett = itemAtIndex; // I THINK I MUST PUT HERE MY MISSING CODE } } @end EDIT3 #import "Dettagli_Esame.h" @interface Dettagli_Esame () @end @implementation Dettagli_Esame @synthesize nome; @synthesize crediti; @synthesize voto; @synthesize Dett; - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization } return self; } - (void)viewDidLoad {[super viewDidLoad];} EDIT5-6: -(void)viewDidAppear:(BOOL)animated{ NSString *docsDir; NSArray *dirPaths; NSLog(@"Dettagli Esame"); dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); docsDir = [dirPaths objectAtIndex:0]; databasePath = [[NSString alloc] initWithString: [docsDir stringByAppendingPathComponent: @"Esami.sqlite"]]; dataList = [[Data alloc] init:databasePath]; nome.text = [Dett objectForKey:@"nome"]; crediti.text = [Dett objectForKey:@"crediti"]; voto.text = [Dett objectForKey:@"voto"]; NSLog(@"Dettagli Esame: %@", self.Dett); } </code></pre>
