iPhone Keyboard

[lexy0202]

Hi Guys - newbie iPhone developer here:

I know how to remove a keyboard from a UITextField in code, but how do you make an action happen when you press the return or 'done' key... I have tried lots of the events in IB, and they don't seem to do the job.

Add the UITextFieldDelegate in your class. Here some quote from the documents:

textFieldShouldReturn:
Asks the delegate if the text field should process the pressing of the return button. This method is optional.

- (BOOL)textFieldShouldReturnUITextField *)textField

Parameters
textField
The text field whose return button was pressed.

Return Value
YES if the text field should implement its default behavior for the return button; otherwise, NO.

Discussion
The text field calls this method whenever the user taps the return button. You can use this method to implement any custom behavior when the button is tapped.

Sorry, could you explain SLOWLY how to do this in code, as in... I press the return key on my keyboard, it runs my method for me!

First you need to add the delegate to your viewController or class. So in your header file:

From this:
@interface FirstViewController : UIViewController {

To this:
@interface FirstViewController : UIViewController <UITextFieldDelegate> {

Than, in your .m file, create this method:

- (BOOL)textFieldShouldReturnUITextField *)textField
{
    [self myMethodToRun];
    return YES;
}

That's just from the top of my head, but I think it'll work

Hi Alex, could you please tell me the code to remove the keyboard in Iphone simulator once I am done with adding text in the text field.

[dragon_tenvel]

- (BOOL)textFieldShouldReturnUITextField *)aTextField {

if (aTextField == yourTextField)
[yourTextField resignFirstResponder];

return YES;
}

Hiii

in UITextView theres a metod for that:

- (BOOL)endEditing: (BOOL)force

giving TRUE by parameter the keybord goes down.
