Whenever I try to save a NSUserDefualts to a NSMutableArray it crashes - ios

Question

I've been using NSUserDefualts. Whenever I try to save to a NSMutableArray it crashes the app. How would I fix this?
I tried to figure it out online, but it's been bringing up either swift or guides that don't support any of what I searched.
#import "scoutViewViewController.h"
#interface scoutViewViewController ()
#property (weak, nonatomic) IBOutlet UITableView *scoutView;
#end
BOOL check = YES;
#implementation scoutViewViewController
*tableData; // u need this for a standalone/ static one
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
tableData =[[NSUserDefaults standardUserDefaults] objectForKey:#"data_0"];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [tableData count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"SimpleTableItem";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
return cell;
}
//segue select
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"show" sender:self];
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:#"show"]) {
}
}
//ediatable tableView
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
// Return NO if you do not want the specified item to be editable.
return YES;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
[tableData removeObjectAtIndex:indexPath.row];
[tableView deleteRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
[self scoutView];
}
}
- (IBAction)addCell:(id)sender {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Team Name Or Number" message: #"" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Ok", nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];
}
-(void) alertView:(UIAlertView *) alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
//only accept if the user hit ok
// need to implement "UIAlertController" becuase UIAlert is no longer used.
if(buttonIndex == 1){
NSString *temptxtfield = [alertView textFieldAtIndex:0].text;
if(!tableData){
tableData = [[NSMutableArray alloc]init];
}
if([temptxtfield isEqual: #""] || [temptxtfield isEqual: #" "]){
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Team Name Or Number" message: #"" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Ok", nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
check = NO; //check, nothing to do wiht the implemtaiont
}else{
check = YES;//check, nothing to do wiht the implemtaiont
}
if(check == YES){//check, nothing to do wiht the implemtaiont
[tableData insertObject:temptxtfield atIndex:0];
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[self.scoutView insertRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
check= NO;//check, nothing to do wiht the implemtaiont
}//check, nothing to do wiht the implemtaiont
//check is to prevent nothing to be placed into the tabel, nothing to do with how the data is inserted into the table
}
}
- (IBAction)saveTable:(id)sender {
[[NSUserDefaults standardUserDefaults] setObject: tableData forKey:#"data_0"];
}
-(void)save2{
}
#end
It gives me a SIGBART error when it crashes, I tried figuring out with break points but it's being a pain.

Answer 1

ended up figuring it out, pretty simple now that I think of it and I feel pretty dumb not knowing it beofore lol...
tableData = [NSMutableArray arrayWithArray:[[NSUserDefaults standardUserDefaults] objectForKey:#"tabelSave"]];
