iPhone SDK: Can I nab in instance variable from one view and access it in another?

I'm pretty new to OOP in general and just really started working with Obj-c a few months back. So, please be gentle! I appreciate your help in advance. Now to the question!

I have 3 Text Fields where a user inputs name, phone, and email.

I collect and place them in a label using an NSString like this [this is the one for the name]:

- (IBAction)changeGreeting:(id)sender {
self.name = textInput.text;

NSString *nameString = name;
if([nameString length] == 0) {
    nameString = @"I Forgot";
}
NSString *greeting = [[NSSt开发者_StackOverflow中文版ring alloc] 
                      initWithFormat:@"Hello, my name is %@! Really!", nameString];
label.text = greeting;
[greeting release];
} 

With this I have been able to place the text from text.input into my label (as stated in label.text = greeting;)

I have another view where I'd like to have someone review this information (view a label too). I need to have access to name or Textinput.text in that other view.

How can I accomplish this?

If you don't need to communicate changes between the two view controllers, you may want to pass it in using a custom init method. This may be best for a confirmation screen, where the prompt would make no sense without this string.

- (id)initWithFrame:(CGRect)aRect username:(NSString*)aName {
    if((self = [super initWithFrame:aRect])) {
        _myName = [aName retain];
    }
    return self
}

Another option is to implement a method on the first view controller and call it from the second.

- (NSString*)enteredUsername {
    return _myName;
}
