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 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 am using this code to set the parameters of an uitextview i have on my view.
_textview=[[UITextView alloc]init];
[_textview setUserInteractionEnabled:FALSE];
_textview.text=#"Write your message";
_textview.textColor=[UIColor lightGrayColor];
_textview.layer.cornerRadius=6;
_textview.contentInset = UIEdgeInsetsZero;
_textview.delegate=self;
I have in the .h this code
IBOutlet UITextView *_textview;
#property(nonatomic,retain) IBOutlet UITextView *_textview;
I have connected the outlet to the uitextview by using the interface.
What happens is the following:
- (void)textViewDidChange:(UITextView *)inTextView
the above delegate is called but not the following one:
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementString:(NSString *)string
Why is this happening? Am i doing something wrong?
Any help appreciated...
In addition to removing the _textview = [[UITextView alloc]init]; so as to not overwrite your nib loaded textview.
The <UITextViewDelegate> method is:
-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text{}
The correct method signature is:
textView:shouldChangeTextInRange:replacementText:
not:
textView:shouldChangeTextInRange:replacementString:
Because you are typing the method name wrong.
There is no
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementString:(NSString *)string
but only
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
careful with the different between replacementString and replacementText.
Also, as the others said, if you've created the UITextView in IB, you should NOT init it again in your code (but this is not the reason why your delegate never invoked).
I have a viewController with this:
#interface RootViewController : UIViewController <UITextFieldDelegate>{
Then I have a textfield added programmatically like this in viewController.m:
UITextField*textFieldRounded=[[UITextField alloc] initWithFrame:frame];
textFieldRounded.delegate = self;
In the same .m i have tried all of these:
- (void)textFieldDidEndEditing:(UITextField *)textField{
[textField resignFirstResponder];
NSLog(#"returned?");
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
NSLog(#"returned?");
return YES;
}
-(BOOL)textFieldShouldEndEditing:(UITextField *)textField{
[textField resignFirstResponder];
NSLog(#"returned?");
return YES;
}
The keyboard appears fine when I click the text field, which is in a subview of the viewController. but pressing Done does nothing. The NSLog statements never appear, so these methods are never getting called. Any ideas?
I just barely had this question, maybe, but what I did was attached a tap gesture recognizer object to the view, made a instance method called clear keyboard:, and inside the function I put [whateverItIsThatOpenedTheKeyboard resignFirstResponder]; and that's it. Maybe you asking something totally different, but I thought I would try and help :)
Declare the UITextField in .h file as an IBOutlet with property and synthesize it in .m file.
Use this delegate method
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string;
Add this delegate method to your code and run your app once again..
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.

I've been searching the web for a really long time, and I can't get this to work. On my text field I have, when I click on it and then press done or return it won't go away. I've done all the steps for every single tutorial but I still can't get it to work. I'm on firmware 3.1.2, but anyway here is the code in my ViewController.m:
- (void)viewDidLoad {
[super viewDidLoad];
blah.delegate = self;
blah.returnKeyType = UIReturnKeyDone;
}
- (BOOL)blahShouldReturn:(UITextField *)blah{
[blah resignFirstResponder];
return YES;
}
viewcontroller.h:
#interface BlahViewController : UIViewController <UITextFieldDelegate> {
IBOutlet UITextField *blah;
}
These are just cut outs from the files. Anyway can anyone help me? I can't get rid of the keyboard when I click on it...
Thanks,
Kevin
I'm confused. Are you actually expecting a method called blahShouldReturn: to get called when you press the Return button? If you want to use the textFieldShouldReturn: delegate method, it has to be called textFieldShouldReturn:. You can use the UITextField parameter supplied with that method to determine which text field is sending the message. For example:
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
if (textField == blah) {
[textField resignFirstResponder];
} else if (textField == someOtherTextField) {
// Do something else
}
return YES;
}
.m file:
- (void)viewDidLoad {
[super viewDidLoad];
blah.delegate = self;
blah.returnKeyType = UIReturnKeyDone;
//Call hideKeyboard action when done button is clicked
[blah addTarget:self action:#selector(hideKeyboard) forControlEvents:UIControlEventEditingDidEndOnExit];
}
//Custom hide keyboard action
- (void)hideKeyboard {
[blah resignFirstResponder];
}
.h file:
//Dont need delegate for this method of hiding keyboard!
#interface BlahViewController : UIViewController {
IBOutlet UITextField *blah;
}
- (void)hideKeyboard;
#end
