Dismissing the keyboard in the iPhone 101 Tutorial

Question

Is anyone able to dismiss the keyboard in creating the app in the iPhone 101 tutorial? I have literally copied and pasted the code from the View Controller implementation and interface files, and the keyboard still doesn't go away when I click "Done." In fact, if I place a breakpoint in the textFieldShouldReturn method, the app doesn't stop and the debugger never breaks. It's like the UITextField never fires off textFieldShouldReturn. I've even tried to set the view as the delegate, as other threads have suggested:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
textField.delegate = self;
changeGreeting, though, works just fine. This is in the simulator using Beta 5, by the way. I haven't tried it on a device just yet.
Here's my controller's interface code:
#import <UIKit/UIKit.h>
@interface MyViewController : UIViewController <UITextFieldDelegate> {
IBOutlet UITextField *textField;
IBOutlet UILabel *label;
NSString *string;
@property (nonatomic, retain) UITextField *textField;
@property (nonatomic, retain) UILabel *label;
@property (nonatomic, copy) NSString *string;
- (IBAction)changeGreeting:(id)sender;
@end
And here's my controller's implementation code:
#import "MyViewController.h"
@implementation MyViewController
@synthesize textField;
@synthesize label;
@synthesize string;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
textField.delegate = self;
if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {
// Initialization code
return self;
- (IBAction)changeGreeting:(id)sender {
self.string = textField.text;
NSString *nameString = string;
if ([nameString length] == 0) {
nameString = @"World";
NSString *greeting = [[NSString alloc] initWithFormat:@"Hello, %@!",
nameString];
label.text = greeting;
[greeting release];
- (BOOL)textFieldShouldReturn:(UITextField *)theTextField {
if (theTextField == textField) {
[textField resignFirstResponder];
return YES;
Any help would be appreciated.

Thank you akollegger! I found that I needed to make sure you have all the appropriate connections. In the "Configuring the View" page (http://developer.apple.com/iphone/library/documentation/iPhone/Conceptual/iPhone 101/Articles/05_ConfiguringView.html), I found that I had missed the following line in the "Making Connections" section:
Connect the label and textField outlets. Control click File’s Owner to display a translucent panel that shows all the available outlets and actions, then drag from the circle to the right of the list to the destination to make the connection.
The picture shows you how to connect the label, but the text tells you that you need to connect both the label and the textField outlets.
When I went back and looked at the outlets for MyViewController (double click on MyViewController.xib, Ctr-click on "File's Owner"), I noticed that I had an outlook connection from "label" to a Label and mousing over it highlighted the label in the View. It took a while to realize that I was missing the connection between "textField" and the UITextField in the View. Without that connection, there is no routing of the textFieldShouldReturn event from the keyboard.
To fix the problem, drag from the open circle next to "textField" to the UITextField in the View. Voila!
Hope this helps!
