I have such a problem: I have a UITextField in my UITableViewCell. When I tap on that text field -> keyboard appears, but when I press Enter button keyboard don't disappear. I need such a behavior for my text field and keyboard:
When I pressed Enter, Esc - keyboard must disappear.
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
Where textField is UITextField in UITableViewCell
Implement textFieldShouldReturn: method in textField's delegate and call [textField resignFirstResponder] there - that will hide keyboard when return key is pressed.
I'm not sure if that will work for 'Esc' as well, but there's no such key on real device anyway so it must not be a problem
Try this
[txtField setReturnKeyType:UIReturnKeyDone];
txtField.enablesReturnKeyAutomatically=YES;
This may be an old post but I found it searching for the answer so chances are someone else might so don't shoot me for posting.
Just wanted to add
don't forget to make the delegate connection in IB for the UITextField
#interface Untitled2ViewController : UIViewController <UITextFieldDelegate>
{
IBOutlet UITextField *text;
}
#property (nonatomic, retain) IBOutlet UITextField *text;
#end
//m file
#import "Untitled2ViewController.h"
#implementation Untitled2ViewController
#synthesize text;
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
In xib file I set: Return Key: Done, Auto-anabling return key. I also tried without it, and still no reaction. Keyboard don't hides.
Write this code to create UITextLabel
UITextField *username = [[UITextField alloc]initWithFrame:CGRectMake(10.0f, 10.0f, 110.0f, 30.0f)]
[username setReturnKeyType:UIReturnKeyNext];
[username setDelegate:self];
[self.view addSubview:username];
Now to resign write this code.
-(void)resignKeyboard
{
if([username isEditing])
{
[username resignFirstResponder];
}
}
I hope it works for you.
try this
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
or this is for anywhere in the view
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
[self.view endEditing:YES];
}

i'm working on an app which has a tableView with a textField in the right side of its each cell(there are more than 20 cells).
i've created custom cell's for each row except for the last one.
In the last row there is only a button.
Now i want to call resignFirstResponder on the button's click.
What should i do Please help?
You will have to keep track of which textfield in which cell has the first responder and resign it like this.
[myCellTextField resignFirstResponder];
You probably want to keep track of the text field with the keyboard. Implement the <UITextFieldDelegate> protocol in your controller, and set the controller as each of the text fields' delegates. Write the textFieldDidBeginEditing: method like so, setting an instance variable called currentTextField:
- (void)textFieldDidBeginEditing:(UITextField *)textField {
currentTextField = [textField retain];
}
Then, in your action for the button run [currentTextField resignFirstResponder].
Aopsfan's answer is probably the best solution so far. However, to add to it (as I cannot post comments), do remember to deallocate the object:
- (void)textFieldDidBeginEditing:(UITextField *)textField {
if (currentTextField != nil) {
[currentTextField release];
}
currentTextField = [textField retain];
}
Better still use #property's and #synthesize so the runtime can do the memory management for you.
[ViewController].h
#property (nonatomic, retain) UITextField* currentTextField;
[ViewController].m
#synthesize currentTextField = _currentTextField;
- (void)viewDidLoad|Appear {
self.currentTextField = nil;
}
- (void) dealloc {
[_currentTextField release], _currentTextField = nil;
...
[super dealloc];
}
- (void)textFieldDidBeginEditing:(UITextField *)textField {
self.currentTextField = textField;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if (self.currentTextField) {
[self.currentTextField resignFirstResponder];
}
}
I think this link will help you:
Objective C: ResignFirstResponder with a button
Provide some code so that, it will be easier to help u.
Hope this helps you. :)
I am using a UITEXTVIEW. I am trying to send a resignFirstResponder when the done button is pressed. I am not sure how to trigger the method containing the resignFirstResponder line.
I have set the UITextView's delegate to the File's Owner in Interface Builder. This is my viewcontroller's header and implementation file:
#import <Foundation/Foundation.h>
#import "Question.h"
#interface CommentQuestionViewController : UIViewController {
Question *question;
IBOutlet UILabel *questionTitle;
IBOutlet UITextView *inputAnswer; //this is the textview
}
#property (nonatomic, retain) UILabel *questionTitle;
#property (nonatomic, retain) Question *question;
#property (nonatomic, retain) UITextView *inputAnswer;
- (void) addButton:(id)sender isLast:(BOOL)last;
- (void) setQuestionId:(NSString*)quId withTitle:(NSString*)quTitle number:(NSString*)quNum section:(NSString*)sId questionType:(NSString*)qt;
#end
#import "CommentQuestionViewController.h"
#implementation CommentQuestionViewController
#synthesize questionTitle, question, inputAnswer;
- (void) addButton:(id)delegate isLast:(BOOL)last{
UIBarButtonItem *anotherButton;
anotherButton = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStylePlain target:delegate action:#selector(finishQuestionnaire:)];
self.navigationItem.rightBarButtonItem = anotherButton;
[anotherButton release];
}
-(void)viewDidLoad{
//self.questionTitle.text = question.qTitle;
[[self questionTitle] setText:[question qTitle]];
[super viewDidLoad];
NSString *str = [NSString stringWithFormat:#"Question %#", [question qNumber]];
//self.title = str;
[self setTitle:str];
[str release];
}
-(void) setQuestionId:(NSString*)quId withTitle:(NSString*)quTitle number:(NSString*)quNum section:(NSString*)sId questionType:(NSString*)qt{
question = [[Question alloc]init];
[question setQId:quId];
[question setQTitle:quTitle];
[question setQNumber:quNum];
[question setSectionId:sId];
[question setQType:qt];
}
- (void) viewWillAppear:(BOOL)animated{
self.navigationItem.hidesBackButton = YES;
}
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
- (void) textViewDidEndEditing:(UITextView*)textView{
[textView resignFirstResponder];
}
- (void)viewDidUnload {
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[inputAnswer release];
[questionTitle release];
[question release];
[super dealloc];
}
You can try this:
–(BOOL)textView:(UITextView*)textView shouldChangeCharactersInRange:(NSRange)range replacementText:(NSString*)text {
if ([text isEqualToString:#"\n"]) {
[textView resignFirstResponder];
return NO;
}
else
return YES;
}
Of course, you won't be able to type actual carriage returns if you do this.
After looking at your source code, the link that I had posted is pointless. I thought you were talking about the done key on the keyboard. But now I see that you were talking about an instance UIButton on the navigation bar, right?
Your addButton:isLast: method is looking great so far, but I'd change it a bit so it adheres to the Apple HIG:
- (void)addButton:(id)delegate isLast:(BOOL)last
{
UIBarButtonItem *anotherButton;
anotherButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone
target:delegate
action:#selector(finishQuestionnaire:)];
self.navigationItem.rightBarButtonItem = anotherButton;
[anotherButton release];
}
It's pretty much the same, except this one creates a button with the appropriate style.
Anyway, I don't see how the button is being added since addButton:isLast: is not being called in viewDidLoad:. Add the following line in your viewDidLoad:.
[self addButton:self isLast:NO];
last is redundant in your addButton:isLast: since it's not even being use so I just pass whatever (NO).
You're almost done, but if you press that button, your application would crash since finishQuestionnaire: is not implemented on self (CommentQuestionViewController). And since you want to dismiss the keyboard when the user presses your done button, that's where we will also resign your text view as first responder. Just add the following method:
- (void)finishQuestionnaire:(id)sender
{
[inputAnswer resignFirstResponder];
}
It's BOOL that's it..
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
if([text isEqualToString:#"\n"]) {
[textView resignFirstResponder];
return NO;
}
return YES;
}
If that doesn't work please check the following things..
Whether your textView is connected to the textView property defined in your class.. (You can see this in your xib, with an arrow icon).
2.Check whether the textView delegate is written in your .h file.
#interface YourViewController : UIViewController <UITextViewDelegate>
3.Check whether the textView's delegate is assigned.
//set this in the viewDidLoad method
self.textView.delegate = self;
Check for new line character by this method.
-(NSRange)rangeOfCharacterFromSet:(NSCharacterSet *)aSet
Then check the length of the text, if it is one character length, then new line character is entered, not pasted.
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
BOOL hasNewLineCharacterTyped = (text.length == 1) && [text rangeOfCharacterFromSet:[NSCharacterSet newlineCharacterSet]].location != NSNotFound;
if (hasNewLineCharacterTyped) {
[textView resignFirstResponder];
return NO;
}
return YES;
}
Is there a way to make a UITextField non-editable by the user and provide only a copy menu without subclassing? I.e when the text field is touched it automatically selects all the text and only shows the copy menu.
If possible to do this without subclassing what are the interface builder options that need to be selected?
Thanks in advance.
simply do:
(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string{
return NO;
}
and also:
yourTextField.inputView = [[UIView alloc] init];
You can disable editing by setting the enabled property of UITextField to NO.
textField.enabled = NO;
Note that doing this will also disable the copy/paste options.
What you are asking for has been discussed before in this solution: Enable copy and paste on UITextField without making it editable
Without subclassing, but also without auto-selection, i.e the user can select, keyboard shows up, but the user cannot input data:
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string{
return NO;
}
Items required to make a UITextField (in this case, outputTextField)
able to accept touch and allow Select, Select All, Copy, Paste, but
NOT edit the area and also DISABLE popup keyboard:
Put "UITextFieldDelegate" in angle brackets after ViewController declaration in #interface
In the -(void)viewDidLoad{} method add the following two lines:
self.outputTextField.delegate = self;
self.outputTextField.inputView = [[UIView alloc] init];
Add delegate method (see actual method below):
textField: shouldChangeCharactersInRange:replacementString: { }
// ViewController.h
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController
#end
// ViewController.m
#import "ViewController.h"
#interface ViewController () <UITextFieldDelegate>
#property (weak, nonatomic) IBOutlet UITextField *inputTextField;
#property (weak, nonatomic) IBOutlet UITextField *outputTextField;
- (IBAction)copyButton:(UIButton *)sender;
#end
#implementation ViewController
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range
replacementString:(NSString *)string
{
NSLog(#"inside shouldChangeCharactersInRange");
if (textField == _outputTextField)
{
[_outputTextField resignFirstResponder];
}
return NO;
}
- (void)viewDidLoad {
[super viewDidLoad];
self.outputTextField.delegate = self; // delegate methods won't be called without this
self.outputTextField.inputView = [[UIView alloc] init]; // UIView replaces keyboard
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}
- (IBAction)copyButton:(UIButton *)sender {
self.outputTextField.text = self.inputTextField.text;
[_inputTextField resignFirstResponder];
[_outputTextField resignFirstResponder];
}
#end
This worked for me to have UITextField non Editable and only allow copy. Just change your UITextField Class to CopyAbleTF from XIB and you are set.
#implementation CopyAbleTF
- (void)awakeFromNib{
self.inputView= [[UIView alloc] init];
}
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
if (action == #selector(copy:))
{
return true;
}
return false;
}
- (void)copy:(id)sender {
UIPasteboard *board = [UIPasteboard generalPasteboard];
[board setString:self.text];
self.highlighted = NO;
[self resignFirstResponder];
}
#end
I am new to iPhone development.
I have a UITextField, in that when I press enter I need to hide the keyboard.
Any way to accomplish this?
Implement the UITextFieldDelegate protocol's textFieldShouldReturn: method, and return YES based on the object that is passed in.
- (BOOL) textFieldShouldReturn:(UITextField *) textField {
[textField resignFirstResponder];
return (textField == someTextField);
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
(BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
First if the textfield global object is myTextField then <br>
In .h file <br>
#interface MyScreen : UIViewController <**UITextFieldDelegate**>
{
UITextField *myTextField;
}
#property (nonatomic,retain) IBOutlet UITextField ***myTextField**;<br>
In .xib <br>
Attach myTextField to the control.<br>
In .m File <br>
- (void) viewDidLoad<br>
{
[super viewDidLoad];
myTextField.delegate = self;
}
If you want to return the keyboard on particular return button of keyboard press: <br>
#pragma mark UITextFieldDelegate
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
If you want to return on your particular button <br>
- (IBAction) myButtonPressed:(id)sender
{
[self.myTextField resignFirstResponder];
}
Apologise for my bad english.

Is possible to know when the user touch the keyboard iphone? When the user touch some button from keyboard... :/
The easiest way is to use a TextField. Even is your UI Does not call for one, you can set it's frame to zero so it doesnt show up onscreen. Then you can get access to the keys pressed by using the text field's delegate callback methods.
- (void)viewDidLoad {
[super viewDidLoad];
//CGRectZero because we don't want the textfield to be shown onscreen
UITextField *f = [[UITextField alloc] initWithFrame:CGRectZero];
//We set the delegate so we can grab keypressed
f.delegate = self;
[self.view addSubview:f];
[f becomeFirstResponder]; //Show the keyboard
}
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range
replacementString:(NSString *)string {
if (string.length >0) {
NSLog(#"%# Pressed",string);
}
else {
NSLog(#"Backspcae pressed");
}
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
NSLog(#"return pressed");
return YES;
}
Note: to avoid a compiler warning, make sure in your .h file the class explicitly says it implements the UITextFieldDelegate protocal. ie:
#interface MyViewController : UIViewController <UITextFieldDelegate>
