Best way to pass variables between views

Question

I am very new to xcode & Objective-C (having come from PHP) i have started to play around and am finding it very hard to pass variables between views this is what i have

Answer 1

Take this in .h file in SecondViewController

NSString *strABC;

Make below function in SecondViewController.m

-(void)setString:(NSString *)strEntered{
    strABC=strEntered;
}

Now In First view controller do like this:

SecondViewController.m *objSecond = [[SecondViewController.m] initwithNibName:@"secondView.xib" bundle:nil];

[objSecond setString:@"Comment Controller"];
[self.navigationController pushViewController:objSecond animated:YES];
[objSecond release];

Now, In secondViewController viewWillAppear Method write this.

-(void)viewWillAppear:(BOOL)animated{
      lblUserInput.text = strABC;
}

Please check spelling mistakes as I hand written this. Hope this help.

If you are not using navigationContoller then you can do something like this.

SecondViewControler *objSecond = [[SecondViewController] initwithNibName:@"secondview.xib" bundle:nil];
[objSecond setUserInput:txtUserInput.text];
[objSecond viewWillAppear:YES];
[self.view addSubview:objSecond];
[objSecond release];
