Question

Alright, I’ll try and make this as simple as possible (I was seeming to get the run around on chat.stackoveflow.com when I tried asking this question). I want to pass the text from a textfield in one viewcontroller to another viewcontroller.

Should I use a Model class and store the the textfield.text in a Model.[h/m] files and then have the second view controller access the data stored in the model?

Basically this is what I have,

ViewControllerWelcome.h

@interface ViewControllerWelcome : UIViewController { }

@property (weak, nonatomic) IBOutlet UITextField *textFieldUsername;

ViewControllerWelcome.m

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
                ViewControllerHome *home = (ViewControllerHome *)[storyboard instantiateViewControllerWithIdentifier:@"Home"];
                NSString *username = _textFieldUsername.text;
                home.lblUSERNAME.text=username;
                [self presentModalViewController:home animated:YES];

ViewControllerHome.h

@interface ViewControllerHome : UIViewController {
NSString *username;
UILabel *lblUSERNAME;
}

@property (weak, nonatomic) IBOutlet UILabel *lblUSERNAME;

ViewControllerHome.m

- (void)changeUSERNAME {

 // get username from welcome tf
ViewControllerWelcome *welcome = [[ViewControllerWelcome alloc] init];
 welcome.username = [self lblUSERNAME.text];
 // _lblUSERNAME.text = welcome._textFieldUsername.text;
 //welcome.textFieldUsername.text = _username;
 // username = welcome.textFieldUsername.text;
 NSLog(@"username = %@",username);
// welcome.textFieldUsername.text = _lblUSERNAME.text;
// NSLog(@"username = %@",welcome.textFieldUsername.text);
}    

As you can see I tried several different things, but couldn’t come up with a working solution :-l

I refined this question with another question on SO that can be found here Basically, I created a singleton to pass the data between the view controllers. I haven’t had any problems with it so far (knocks on wood).
