UITableViewCell and resignFirstResponder

Question

I have a UITableView containing in each cell a UITextField. When the user clicks on the UITextField, as expected, the keyboard will popup.

I have implemented in my delegate tableView: didSelectRowAtIndexPath: method to dismiss the keyboard with resignFirstResponder sent to the last UITextField used.

Everything works ok if the cell with the last UITextField used is displayed.

Now, if I scroll down to bottom of the tableview and press on a row, then the resignFirstResponder is sent to a hidden UITextField and will not hide the keyboard. It doesn't throw an error also.

How can I hide the keyboard in such cases?

why don't you use the return key ? – Legolas Jul 27 '11 at 00:16 — Legolas, Jul 27 '11 at 00:16

Have a look at UITextFieldDelegate and put the

[textField resignFirstResponder];

method in one of the callback functions. I particulary prefer:

- (BOOL)textFieldShouldReturn:(UITextField *)textField;

- (BOOL)textFieldShouldReturn:(UITextField *)textField; is not called at all in my case. – CristiC Jul 27 '11 at 15:29
This method is called when the return/done button is clicked. If this does not suit you exactly you should choose a callback for another action. – Teodor Kostov Jul 27 '11 at 20:03

My keyboard type is Number Pad, so I don't have return/done button. And I don't need it for anything else, so I think the method will not work... – CristiC Jul 28 '11 at 07:09
Have you read my last comment? My keyboard type is Number Pad. There is no return, done, go and so on... button on the bottom right side. Only delete button. – CristiC Jul 28 '11 at 14:52
For example there is `-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string`. This is called whenever a new character is typed. Or checkout [this post](http://stackoverflow.com/questions/1823317/how-do-i-legally-get-the-current-first-responder-on-the-screen-on-an-iphone). Or you should consider using `UIKeyboardTypeNumbersAndPunctuation`. However, if you are not able to close your keyboard through delegation, maybe you should change your code design a bit. – Teodor Kostov Jul 29 '11 at 02:59

Thanks. That post solved it. I just had to add [self.view endEditing:YES]; – CristiC Jul 30 '11 at 09:13

Did you try calling endEditing:YES method of the UITextField?

This should make the first responder to resign. It doesn't matter keyboard type. Not sure this will work, but you can try :) – Manlio Jul 26 '11 at 22:34
Nope, doesn't work. Not with endEditing or setEditing (like you initially mentioned). – CristiC Jul 26 '11 at 22:39
setEditing was wrong because editing property is read-only, just made a bit of confusion... – Manlio Jul 26 '11 at 22:43

-(IBAction)hidekey:(id) sender{

[textField resignFirstResponder];
}

if you using Interface builder then checked outlet of text field and in .m file use above function and define for that text field. It will work.

Please explain better... What do you mean by "if you using Interface builder then checked outlet of text field"? Especially "then checked outlet of text field"? – CristiC Jul 27 '11 at 13:38
