nsmutable array not saving values - objective-c

Question

My array is not saving the values I put in it...
I am defining my nsmutablearray *arrayClientList in .h file
#interface StartupTableViewController : UIViewController<UITableViewDataSource, UITableViewDelegate>
#property (strong, nonatomic) IBOutlet UITableView *tableView;
#property NSMutableArray *arrayClientList;
#property BOOL boolAddToClient;
//#property (strong, nonatomic) NSMutableArray *arrayAddClient;
#end
in .m file I am initializing like so
- (void)viewDidLoad {
[super viewDidLoad];
//initialize variables
self.arrayClientList = [[NSMutableArray alloc] init];
arraySelectedInformation = [[NSMutableArray alloc] init];
self.boolAddToClient = NO;
NSString *tstring = #"hello";
[self.arrayClientList addObject:tstring];
but then once I get to another method in this same class... the array is nil again. I must be doing something stupid for the array not to hold the values
-(void)viewDidAppear:(BOOL)animated{
//NSLog(#"appeared");
if (self.boolAddToClient) {
NSLog(#"add client to list");
self.boolAddToClient = NO;
[self.tableView reloadData];
}
else{
NSLog(#"startup");
}
}
I am trying to use it in another class
- (IBAction)buttonSubmit:(id)sender {
NSString *userDescription = [[NSString alloc] init];
NSString *userUsername = [[NSString alloc] init];
NSString *userPassword = [[NSString alloc] init];
userDescription = self.textfieldDescription.text;
userUsername = self.textfieldUserID.text;
userPassword = self.textfieldPW.text;
//check to make sure user filled out all fields
if (![userDescription isEqual:#""] && ![userUsername isEqual:#""] && ![userPassword isEqual: #""]){
NSLog(#"correct");
NSArray *arrayVC = self.navigationController.viewControllers;
StartupTableViewController *parentViewController = [arrayVC objectAtIndex:0];
parentViewController.boolAddToClient = YES;
NSMutableArray *arrayNewObjects = [[NSMutableArray alloc] initWithObjects:userDescription, userUsername, userPassword, nil];
NSMutableArray *tarray = parentViewController.arrayClientList;
[tarray addObject:arrayNewObjects];
[parentViewController.arrayClientList addObject:arrayNewObjects];
[self.navigationController popViewControllerAnimated:YES];
}
else{
NSLog(#"something missing");
}
}

Since I can't comment without rep, I must try with answer.
Try this:
In ViewDidLoad do alloc init with Strings you create in implementation and also change if block to this:
#implementation
{
NSString *userDescription;
NSString *userUsername;
NSString *userPassword;
}
-(void)viewDidLoad {
[super viewDidLoad];
NSString *userDescription = [[NSString alloc] init];
NSString *userUsername = [[NSString alloc] init];
NSString *userPassword = [[NSString alloc] init];
}
- (IBAction)buttonSubmit:(id)sender {
if (self.textfieldDescription.text.lenght != 0 && self.textfieldUserID.text.lenght != 0 && self.textfieldPW.text.lenght != 0) {
userDescription = self.textfieldDescription.text;
userUsername = self.textfieldUserID.text;
userPassword = self.textfieldPW.text;
....... and the rest
}
Please comment if it's not working, and I also think that you're not passing the informations right. Try searching an answer on how to pass arrays between TableViewControllers. Good Luck!
