Like this:

//header

@interface MyView : UIView
{
IBOutlet UITextField *name;
}

- (IBAction)doneButtonOnKeyboardPressed: (id)sender;

//m-file

@implementation MyView

- (IBAction)doneButtonOnKeyboardPressed: (id)sender
{}

@end

It seems like there is a lot of confusion surrounding this topic, so here is a code example showing how to programatically create a functional UITextField

/*
MyTextFieldView.h
The important notes here are that we have...
1. A new class of superclass UIView
2. The class contains a UITextField class member
3. The class implements the UITextFieldDelegate interface
*/
#import <UIKit/UIKit.h>

@interface MyTextFieldView : UIView <UITextFieldDelegate>{
	UITextField *my_text_field;
}

@end

/*
MyTextFieldView.m
*/


#import "MyTextFieldView.h"

@implementation MyTextFieldView

- (id)initWithFrame:(CGRect) myframe {
        self = [super initWithFrame:myframe];

        //Setup the location of the text field (top, full width)
	int w = [[UIScreen mainScreen] applicationFrame].size.width;
        CGRect text_field_rect = CGRectMake(0,0,w,30);

        //initialize the text field
	my_text_field = [[UITextField alloc] initWithFrame:text_field_rect];
	
       //tell the text field that MyTextFieldView will handle its events
       [my_text_field setDelegate:self];

        //A little visual formatting to make things pretty
	my_text_field.borderStyle = UITextBorderStyleBezel;
        my_text_field.textColor = [UIColor blackColor];
	my_text_field.font = [UIFont systemFontOfSize:17.0];
        my_text_field.placeholder = @"<enter text>";
        my_text_field.backgroundColor = [UIColor whiteColor];	

       //add the text field to the view
       [self addSubview:my_text_field];

       return self;
}

//UITextFieldDelegateMethods
//When the keyboard return button is pressed...
//The UITextField "my_text_field" tells its delegate (ie this
//instance of MyTextFieldView) to call the method "textFieldShouldReturn"
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
        //We resign the first responder
        //This closes the keyboard
	[textField resignFirstResponder];

        //Do what ever other fanciness you want
        //TODO: fanciness

        //Return YES to confirm the UITextField is returning
	return YES;
}

- (void)dealloc {
    [super dealloc];
}


@end

hope that helps

Dismisses the keyboard just fine.

code in the viewcontroller.m

-(IBAction)fakeid)sender
{
[passkey resignFirstResponder];
[upc resignFirstResponder];
[registrantId resignFirstResponder];
}

code in the viewcontroller.h

-(IBAction)fake: (id) sender;

in IB pointed my text fields to fileowner fake


PUURFECT thanks for the post

The key piece of code being:

@interface MyTextFieldView : UIView <UITextFieldDelegate>{

That's what allows you to delegate the UITextField to MyTextFieldView and use the textFieldShouldReturn method.

Hey i had the same problem. Call the UITextFieldDelegate protocol. and then try mytextfield.delegate=self;
if this doesnt work load ur textfield programtically n not using IB.
Dont forget to add the -(BOOL) textFieldShouldreturn method from textfieldDelegate.

If you want values from Picker to be loaded. Load the pickerview in textfieldShouldBeginEditing method...

ignore if this you already know...

Since I am so tired of you guys asking all of these dumb questions, I will give a good response in the hopes that you guys will stop asking them:

Before we begin, make sure you have added UITextFieldDelegate (or UITextViewDelegate) delegate in the <> in the header file's interface.

In order to dismiss a keyboard, you must first have a UITextField or UITextView. Those two classes are exactly the same, except UITextView is a UITextField with a UIScrollView in it. This means that everything that works with UITextField will work with UITextView (minus a few things).

To dismiss a keyboard, we want to call [textField resignFirstResponder];
(where textField is any UTextField or UITextView)

However, Just dismissing it anywhere is probably against apple's guidelines.

This is why we use the delegate, in order to dismiss the keyboard, create an IBAction and call the aforementioned thingy (or use a delegate method)

If you used the delegate method, make sure that you used the one that starts with textFieldDidEndOnExit.

Otherwise, connect the IBAction to the UITextField (or UITextView) for the event: DidEndOnExit.

you now have a UITextField (or UITextView) that dismisses when the return button is pressed.

One more thing: make sure to set the textField's delegate to self in the viewDidLoad method!!!!
