I just can't make the "Done" button to quit the keyboard.
I used this in my controller.h file
- (IBAction)textFieldDoneEditing:(id)sender;
and this for my controller.m file
- (IBAction)textFieldDoneEditing:(id)sender {
[sender resignFirstResponer];
}
and I'm mixed up in wiring the .xib part.
Make the controller a delegate of the UITextField/UITextView in IB or from code like textField.delegate = self;
Editted:
For this you need to declare the controller a delegate of UITextFieldDelegate/UITextViewDelegate as
#interface Controller : <UITextFieldDelegate> { ...
, then override the method:
-(BOOL)textFieldShouldReturn:(UITextField *)textField{
[textField resignFirstResponder];
return YES;
}
for UITextField and
-(BOOL)textViewShouldEndEditing:(UITextView *)textView{
[textView resignFirstResponder];
return YES;
}
for UITextView
In your .xib, right click on your text view, drag to "File's Owner", and click "delegate". Should work now?
Edit: Whoops, sorry I'm an idiot, do what that other guy says. If you don't know how to set the delegate in code though, you can do it my way in IB.
Let me make my first contribution:
If you have multiple text fields, group them in a #property (strong, nonatomic)
*.h
#property (strong, nonatomic) IBOutletCollection(UITextField) NSArray *collectingData;
*.m
-(BOOL)textFieldShouldReturn:(UITextField *)boxes
{
for (UITextField *boxes in collectingData) {
[boxes resignFirstResponder];
}
return YES;
}

I have set the image to textFiled using rightmodeview on clicking button,
now what I want is, I want to hide the image on tapping the textField without touching button?
Help me out
Do something like:
-(void)textFieldDidBeginEditing:(UITextField *)textField {
textfield.rightView=nil;
//Do other stuff,if you want to do
}
I created sample one and I tried it works fine.
ViewController.h
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController<UITextFieldDelegate>
#property (strong, nonatomic) IBOutlet UITextField *txtFldImage;
#end
ViewController.m
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
txtFldImage.rightViewMode = UITextFieldViewModeAlways;
txtFldImage.rightView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"boss-icon.png"]];
}
-(void)textFieldDidBeginEditing:(UITextField *)textField{
txtFldImage.rightView = nil;
}
When run the app
When I enter or touch the textField
this code is working for me
-(void)textFieldDidBeginEditing:(UITextField *)textField {
//set right view nil
}
and make sure you set delegate of UITextField for your textfield
Add below code in viewDidLoad
yourTextField.delegate = self;
I'd like to thanks you in advance for your answers. I read all stuff about this but I couldn't solve it.
I know how to hide keyboard on UITextField, just like this:
- (BOOL)textFieldShouldReturn:(UITextField *)textField{
[placename resignFirstResponder];
[address resignFirstResponder];
return YES;
}
But I also have an UITextView and I don't know how to hide it. I don't want to hide it with a button I want to hide it with a "Done" in the return.
I read something like this:
[textField setReturnKeyType: UIReturnKeyDone];
But... how and where to implement it? I'm new on this so I need to know it step by step,please.
Thanks so much.
(Sorry I'm not able to send an image...new user ;) )
Its easy. Have textview delegate in your controller and add following method.
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
if([text isEqualToString:#"\n"]) {
[textView resignFirstResponder];
return NO;
}
return YES;
}
There is one disadvantage using this, user can not write multi line statements. To solve this you can have a create view over keyboard and have button over there and add action to resign your textview.

Additional to #JanakNirmal Answers, the code for the .h and .m. Works fine for me.
.h
#interface ViewController : UIViewController <UITextViewDelegate>
#property (weak, nonatomic) IBOutlet UITextView *textField; // connected with IB
#end
.m
#interface ViewController ()
- (void)viewDidLoad
{
[super viewDidLoad];
// Done key and hide keyboard
[self.textField setDelegate:self];
[self.textField setReturnKeyType:UIReturnKeyDone];
}
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
if ([text isEqualToString:#"\n"])
{
[textView resignFirstResponder];
}
return YES;
}
#end
I have a DetailViewController, which implementation file contains this code:
#import <UIKit/UIKit.h>
#interface DetailViewController : UIViewController <UITextFieldDelegate>
{
__weak IBOutlet UITextField *nameField;
__weak IBOutlet UITextField *numberField;
}
#end
In my storyboard, I have set the ViewController's to DetailViewController and connected the delegate of both of my UITextFields to my DetailViewController. The implementation file of my DetailViewController contains this method to dismiss the keyboard when tapping somewhere other than the text field:
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
This method is not called though, I have tested this using a breakpoint. What could be going wrong?
rdelmar is correct, the code you have only gets triggered when the user hits the "return" key on the keyboard, not when they click outside of the keyboard.
To get the behavior you are looking for, I'd add a Tap Gesture Recognizer to the view behind your text field, then put [nameField resignFirstResponder]; and [numberField resignFirstResponder]; in the tap gesture recognizer's code.
I created a sample project
added to the viewcontroller
added a textfield and connected its delegate
write the code in viewcontroller
(BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
it worked fine.Tried weak it also worked both as instance variable and property
So check if that you are reallocating it anywhere and also check its memory is same there using breakpoint
Why do you use _weak? Remove it.
In your .m file do (in viewDidLoad):
[nameField setDelegate:self];
Same for the other textfield(s).
I have UITextField and I have
#property (nonatomic, assign) id <UITextFieldDelegate> delegate;
After pressing a done button on keybord, it should dismiss. Can someone tell how I can do it using this property?
The dismissing of the keyboard does not happen merely by being a delegate of the UITextField. Your delegate must dismiss it.
In the viewDidLoad in your controller you must assign the delegate, or set it up in Interface Builder:
- (void)viewDidLoad {
self.textField.delegate = self;
}
Then in your controller, implement the following delegate method.
#pragma mark - UITextFieldDelegate
// This method gets called when you hit the enter key on the keyboard,
// or in this case 'DONE'. The textfield is asking if it should put
// a carriage return in the field. This is our opportunity to dismiss
// the keyboard.
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder]; // This is what hides the keyboard
return NO;
}

Hi I find some questions like that but they talk about textView, I have ViewController, with scrollView where are 6 textfield and one textView I want a function which makes the keyboard disappear on on done/return button click.I implemented functions resign to first responder, which hide my keyboard when i click outside of scrollView, but that is not exactly i want, because i like to make it disappear on button click too.
THanks for any help
Set up a class that conforms to the UITextFieldDelegate protocol and make the delegate of your text fields an instance of this class. Implement the method:
- (BOOL)textFieldShouldReturn:(UITextField *)textField
As follows:
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
Hi i found it out so the point with textfields is to add this lines at viewdidload:
textFieldOne.returnKeyType = UIReturnKeyDone;
textFieldCislo.delegate = self;
textFieldTwo.returnKeyType = UIReturnKeyDone;
textFieldCislo.delegate = self;
...
And this implement method :
-(BOOL)textFieldShouldReturn:(UITextField *)theTextField {
if (theTextField == textFieldOne) {
[textFieldOne resignFirstResponder];
}
...
}
U can use this method to hide the keyboard by clicking any where in the view
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
[self.view endEditing:YES];
}
After quite a bit of time hunting down something that makes sense, this is what I put together and it worked like a charm.
