UINavigationItem.titleView canBecomeFirstResponder?

Question

I have a custom UITextField added to the UINavigationItem.titleView. But it is not becomeFirstResponder. Why so?

- (void) viewDidLoad
{
    [super viewDidLoad];
    UITextField *titleTextField = [[UITextField alloc] initWithFrame:CGRectMake(65.0f, 8.0f, 160.0f, 30.0f)];
    titleTextField.text = @"Untitled";
    titleTextField.textAlignment = UITextAlignmentCenter;
    titleTextField.textColor = [UIColor whiteColor];
    titleTextField.font = [UIFont boldSystemFontOfSize:20.0f];
    //titleTextField.backgroundColor = [UIColor redColor];
    titleTextField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
    titleTextField.delegate = self;
    titleTextField.tag = 2;
    self.navigationItem.titleView = titleTextField;
    [titleTextField becomeFirstResponder]
}

Please advice.

Thanks in Advance, Bharathi.

Your code seems fine... did you try to write above code in `viewWillAppear` ? — Maulik, Jun 12 '12 at 12:45
Do a quick if..statement to see if it can becomeFirstResponder. like if([titleTextField becomeFirstResponder]) — Popeye, Jun 19 '12 at 11:48

Try [self.navigationItem.titleView becomeFirstResponder]; instead of [titleTextField becomeFirstResponder];

You also need to conform the UITextFieldDelegate protocol. I think you do not have conform the protocol.

in .h file (for example)

@interface RootViewController : UITableViewController<UITextFieldDelegate>

@end

Yes.. Have already done that also.. Conformed UITextFieldDelegate in my .h file `@interface ShowListViewController : UIViewController { //code } @end` But still it didn't work.. – Bharathi Jayakumar Jun 12 '12 at 13:17
Great.. Can you share your source code here? I might be doing something wrong somewhere then.. – Bharathi Jayakumar Jun 13 '12 at 10:31

Try this:

[titleTextField becomeFirstResponder];

then:

self.navigationItem.titleView = titleTextField;

Seems like, navigationItem.titleView will not be added to the view hierarchy.. So it won't respond to UIResponderClass... Do correct me If I am wrong... – Bharathi Jayakumar Jun 13 '12 at 06:11
