UITextField setText has no impact before first draw on screen

Question

I have an interface that looks something like this:
@interface PresentationViewController : UIViewController {
IBOutlet UITextField *titleTextField;
I have another class that is connected to the PresentationViewController and displays its view. The code looks somehing like this;
- (void)showPresentationView {
[self presentModalViewController:presentationViewController animated:YES];
presentationViewController.titleTextField = @"Presentation title";
The view is displayed fine with the textfield, but the textfield is blank. I would have expected it be set to "Presentation title". If I dismiss the view and display it again, the title is set fine!
To me it seems like the titleTextField may not have been initialized when I try to set its value the first time.
The presentationViewController is connected to the PresentationViewController through the IB.
Can somebody please tell me what I am doing wrong.
Thank you.

Answer 1

On reconsideration, you don't actually need to synchronize two variables/fields.
Back to your original posting:
- (void)showPresentationView {
[self presentModalViewController:presentationViewController animated:YES];
In the first viewController, you have the variable that you want to use to control the title.
Make sure that is set before you call "presentModalViewController".
presentationViewTitle = @"Presentation title";
Now, in the viewDidLoad method of the presentationViewController, you can reference the original variable (presumed, it is a field defined in the original view controller)
self.titleTextField = self.parentViewController.presentationViewTitle;
The key here is the use of the view controller field, "parentViewController".
