how to update tableview cells using array from nsobject class - ios

Question

When I try to receive data from detail view controller, the master view controller is not added a new cell. I want to update the table view in master view controller based on the array in the detail view-controller. Also cancel button is not work more than one time
This is the master view controller code for save and cancel button.
(void)detailControllerSaved:(DetailViewController *)controller {
if ([self.presentedViewController isEqual:controller]) {
[self.moviesToDisplay addObject:controller.detailItem];
[self dismissViewControllerAnimated:YES
completion:nil];
// it's a modal view
} else {
// it's a navigation view
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
self.moviesToDisplay[indexPath.row] = controller.detailItem;
[self.navigationController popViewControllerAnimated:YES];
}
[self.tableView reloadData];
}
(void)detailControllerCanceled:(DetailViewController *)controller {
if ([self.presentedViewController isEqual:controller]) {
// it's a modal view
[self dismissViewControllerAnimated:YES
completion:nil];
} else {
// it's a navigation view
[self.navigationController popViewControllerAnimated:YES];
}
}
This is my array list
(void) loadSampleContent {
NSArray *movies = #[
[Films movieWithGenre:#"Comedy" title:#"LittleMan " date:#"2006" rate:#"7.5"],
self.moviesToDisplay = [[NSMutableArray alloc] initWithArray:movies];
}
and this is the code in the detail view controller
(void)viewWillAppear:(BOOL)animated {
if(self.detailItem) {
self.movieTitle.text = self.detailItem.movieTitle;
self.genreField.text = self.detailItem.movieGenre;
self.movieRate.text = self.detailItem.movieRate;
self.yearOfMovie.text = self.detailItem.movieDate;
}
}
(void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
(IBAction)Save:(id)sender {
self.detailItem =
[Films movieWithGenre:self.genreField.text title:self.movieTitle.text date:self.yearOfMovie.text rate:self.movieRate.text];
[self.delegate detailControllerSaved:self];
}
(IBAction)cancel:(id)sender {
[self.delegate detailControllerCanceled:self];
}

I think you missed reload table after received data from Detail viewcontroller. Try add reload tableview in mastercontroller in this code:
if ([self.presentedViewController isEqual:controller]) {
[self.moviesToDisplay addObject:controller.detailItem];
[self dismissViewControllerAnimated:YES
completion:nil];
// it's a modal view
}
Hope this help!
