When you click on a textfield in your iphone application, you will get the keyboard displayed. On that keyboard you will get a GO, DONE and SEARCH buttons. I need to get the On click event of these buttons.
What are they ?
become the delegate of the text field in question and you get sent
-(BOOL)textFieldShouldReturn:(UITextField *)textField
When the user taps the return button, whatever the label on the button is. (GO, SEARCH or DONE)

How do I create an hidden button? When I press the button, it creates a UIAlert and asks if I want to buy the product. And when I buy the product, the button will be visible?
If a button is hidden, it is not clickable. Instead, you may want to create a "clear" button. When you press the button, popup the UIAlert and make the button not clear.
I currently am trying to dismiss the keyboard from the previous text field when clicking a button. I currently have one method working to dismiss the keyboard, although it only dismisses it when the user taps away.
you can call this method every time you wanted to resign the
self.view.endEditing(true)
and you can dismiss keyboard from every textfield you wanted , you can call this method :
myTextField.resignFirstResponder()
i want to show my keyboard on screen , whenever a view is shown i.e my login screen..
and i also want to change the name of enter button to Login button.
please help
To change the return key value, change the UIReturnKeyType enum (UITextInputTraits).
If you want the keyboard to show on the screen when it loads, you need to hook up your UITextField to the delegate and include UITextFieldDelegate in your header file. (That is assuming you are using a UITextField.)
Then call:
[textField becomeFirstResponder]
in your viewWillAppear method to give focus to the UITextField which then raises the keyboard.
I have a keyboard which edits text in a UITextView and tapping the return key doenst dismiss the keyboard, it only moves down to the next line.
How can I add a done button and make that dismiss the keyboard?
Implement the
textView:shouldChangeTextInRange
method to look for "\n" then call
resignFirstResponder on the textView if it is found.

The scope of this question is IPhone 3.1 sdk (app running in simulator still)
I have a table view that has a cell with a UITextField in that cell. The table view is grouped, and has one section with just a couple fields. Im NOT using IB so backgroundTap is out of the question (as far as i can tell at least). When i click the text field, keyboard shows. Hiding it is still troublesome. Ive pulled the UITextFieldDelegate into the mix to hide the keyboard but the textFieldShouldEndEditing method doesnt seem to fire when the background is tapped (when i mean background, im tapping outside of the grouped table view section). First off, should it?
textFieldShouldReturn fires with no problem and i can resign at this point but shouldnt i be able to resign if focus shifts away from that control?
Any help is much appreciated

Generally you'll only stop editing a field when you:
hit the "Done" or action button on the keyboard
begin editing another field
exit the view
have another button on screen that removes focus
From any of these, you can call -[textField resignFirstResponder] to dismiss the keyboard and call your -textFieldShouldEndEditing: method. There's no reason that just tapping on a non-active part of the screen should dismiss the keyboard.
