Global array with custom objects is not keeping objects' state - ios

Question

I am creating a bucket list app and I need to be able to save each BucketListGoal from a UITextField in a UITableViewCell. Here is my relevant code below -
#interface BucketListGoalViewController () <UITableViewDataSource, UITableViewDelegate, CreateGoalTableViewCellDelegate, UITextFieldDelegate, UIPopoverPresentationControllerDelegate>
#property (weak, nonatomic) IBOutlet UITableView *tableView;
#property (strong, nonatomic) NSArray *goals;
#property NSInteger path;
#end
#implementation BucketListGoalViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.navigationItem.title = #"Goals";
self.count = 0;
self.goals = [[NSArray alloc] init];
[self createNewGoal];
self.tableView.allowsSelection = NO;;
[self.tableView registerClass:[CreateGoalTableViewCell class]forCellReuseIdentifier:#"Cell"];
[self.tableView registerNib:[UINib nibWithNibName:#"CreateGoalTableViewCell" bundle:nil] forCellReuseIdentifier:#"Cell"];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(handleCoordinatesFromBucketList:)
name:#"Coordinates"
object:nil];
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]
initWithTarget:self
action:#selector(dismissKeyboard)];
[self.view addGestureRecognizer:tap];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"Cell";
CreateGoalTableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];
[cell.textField addTarget:self action:#selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged];
cell.tag = indexPath.row;
cell.delegate = self;
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.textField.tag = indexPath.row;
cell.textField.delegate = self;
BucketListGoal *goal = [self.goals objectAtIndex:indexPath.row];
goal.tag = indexPath.row;
if (goal.address != nil) {
[cell.locationButton setTitle:goal.address forState:UIControlStateNormal];
}
goal.name = cell.detailTextLabel.text;
cell.textField.placeholder = #"Write the description of your goal here.";
cell.numberLabel.text = [NSString stringWithFormat:#"%ld)", (long)indexPath.row + 1];
return cell;
}
-(void)createNewGoal {
BucketListGoal *goal = [BucketListGoal new];
NSMutableArray *copy = [self.goals mutableCopy];
[copy addObject:goal];
self.goals = copy;
[self.tableView reloadData];
}
-(void)textFieldDidChange:(UITextField *)textField{
NSMutableArray *copy = [self.goals mutableCopy];
BucketListGoal *goal = [self.goals objectAtIndex:textField.tag];
goal.name = textField.text;
[copy replaceObjectAtIndex:textField.tag withObject:goal];
self.goals = copy;
}
I create the goal from a bar button item at the top of the view. The issue is that self.goals is only keeping the goal.name of the latest item of the array. All the other previous items from the text fields continue being nil. What am I missing here?
