How to save and load the added player name - ios

Question

I have searched and searched for how to save and load the added player name to a tableview after apps starts, or leaving the view, but I found out nothing.
Hope someone can help me with this issue.
Below is my code :
#interface PlayersViewController ()
#end
#implementation PlayersViewController
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.players = [NSMutableArray arrayWithCapacity:20];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return [self.players count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
PlayerCell *cell = (PlayerCell *)[tableView
dequeueReusableCellWithIdentifier:#"PlayerCell"];
Player *player = [self.players objectAtIndex:indexPath.row];
cell.nameLabel.text = player.name;
return cell;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
[self.players removeObjectAtIndex:indexPath.row];
[tableView deleteRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationLeft];
[self.tableView reloadData];
}
}
- (void)playerDetailsViewControllerDidCancel:
(PlayerDetailsViewController *)controller
{
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)playerDetailsViewControllerDidSave:
(PlayerDetailsViewController *)controller
{
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:#"AddPlayer"])
{
UINavigationController *navigationController =
segue.destinationViewController;
PlayerDetailsViewController
*playerDetailsViewController =
[[navigationController viewControllers]
objectAtIndex:0];
playerDetailsViewController.delegate = self;
}
}
- (void)playerDetailsViewController:
(PlayerDetailsViewController *)controller
didAddPlayer:(Player *)player
{
[self.players addObject:player];
NSIndexPath *indexPath =
[NSIndexPath indexPathForRow:[self.players count] - 1
inSection:0];
[self.tableView insertRowsAtIndexPaths:#[indexPath]
withRowAnimation:UITableViewRowAnimationAutomatic];
[self dismissViewControllerAnimated:YES completion:nil];
}
#interface PlayerDetailsViewController ()
#end
#implementation PlayerDetailsViewController
{
NSString *game;
}
- (IBAction)cancel:(id)sender
{
[self.delegate playerDetailsViewControllerDidCancel:self];
}
- (IBAction)done:(id)sender
{
Player *player = [[Player alloc] init];
player.name = self.nameTextField.text;
[self.delegate playerDetailsViewController:self
didAddPlayer:player];
}
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.section == 0)
[self.nameTextField becomeFirstResponder];
}
- (void)dealloc
{
NSLog(#"dealloc PlayerDetailsViewController");
}

Well, to save your data between application launches, you can rely on this topics: CoreData NSUserDefaults Realm other stuff, like your own server, custom sqlite, etc...
I recommend you start with CoreData guide, that allows you to easy save data between launches.
Hope this may help you.
