I'm trying to hide the iPad keyboard on a modal view, which has the FormSheet style. I tried to resignFirstResponder, but nothing happens. Is this a bug or doesn't this work at all?
best regards
EDIT
-(void)hideKeyboards
{
[emailField resignFirstResponder];
[passwordField resignFirstResponder];
[confirmPasswordField resignFirstResponder];
}
-(IBAction)emailFieldDone:(id)sender
{
[self hideKeyboards];
}
-(IBAction)passwordFieldDone:(id)sender
{
[self hideKeyboards];
}
-(IBAction)confirmPasswordFieldDone:(id)sender
{
[self hideKeyboards];
}
Overriding disablesAutomaticKeyboardDismissal to return NO as below fixed the same problem of mine. You need to override disablesAutomaticKeyboardDismissal of UINavigationController, not the own view controller, to fix this issue. Maybe use a category is a good idea:
- (BOOL)disablesAutomaticKeyboardDismissal {
return NO;
}
Also, check this iPad keyboard will not dismiss if modal view controller presentation style is UIModalPresentationFormSheet question if you want to get a detailed explanation.
try this if you are using textview
Textviewobjectname.editable = NO;
Set delegates to all text field
textField.delegate=self;

i have a screen having navigation controller and text field. when i move next and come back i want the keyboard should be hidden in first screen. I am hiding keyboard like on textfield event.
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
return NO;
}
But how to do that in View related events so that whenever my view appears keyboard is hidden..
Pls guide/Help.
thanks in adv.
I think this is also a good way to remove keyboard with in iOS App if your UITextView or UITextField not connected through the IBOutlet.
If you want to Hide Keyboard with UIViewController LifeCycle Events like with viewWillAppear or etc. Follow this
-(void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[[self view] endEditing:YES];
}
Otherwise if you object connected using IBOutLet this code will work fine as you describe too.
[yourTextField resignFirstResponder];
Add this code to your ViewWillAppear :
for(id obj in self.view.subviews)
{
if([obj isKindOfClass:[UITextField class]])
{
[obj resignFirstResponder];
}
}
This would take in all the textfields in that particular view here it is the whole view and add the code you had written previously for removing the keyboard.
A good habit is to write this code in your screen's -viewWillDisappear. So, when you navigate from one screen to another at that time it will remove the keyboard from that screen.
- (void)viewWillDisappear:(BOOL)animated
{
[self.view endEditing:YES];
[super viewWillDisappear:animated];
}
For multiple textFields, it is better to use -endEditing for that particular view instead of -resignFirstResponder for any single textField. Take a look at my Answer.
//This is for Swift
override func viewWillAppear(animated: Bool)
{
self.view.endEditing(true)
}
The thing that you are doing wrong is , when you are moving back previous controller to the current controller , the keyboard is up due to the selected textfield of previous controller .
And in the current controller the code:
-(void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[[self view] endEditing:YES];
}
It will not work as no textfield is selected at this controller. So what you need to do is write the same code in the previous controller viewWillDisappear Method it will surely resolve your Problem .
- (void)viewWillDisappear:(BOOL)animated
{
[self.view endEditing:YES];
[super viewWillDisappear:animated];
}
I'm using a UITextView and want to keep the normal usage of Return key, i.e. to insert a new line. But how do I dismiss the keyboard when I can't use the Return key for that?
A lot of people add a UIToolbar with a Done button on it above the keyboard. This is how the Safari app does it as well and in my opinion it is the best way to handle this situation. See a pic here.
To dismiss the keyboard, you just have to do [textField resignFirstResponder];.
Here is an okay example of how to add the UIToolbar when the keyboard shows/hides.
How the user triggers it is a design decision: another button, a swipe gesture?
When it's triggered, call:
[self.textView resignFirstResponder];
You could just use a background tap to hide the keyboard.
A good way to Dismiss keyboard.
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView
{
//NSLog(#"ShouldBeginEditing");
if(textView == indexOneTW)
{
here use uibutton and set its target to a method which contains
[urTextView resignFirstResponder]
}
return TRUE;
}
Make sure you declare support for the UITextViewDelegate protocol.
-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText: (NSString *)text
{
if([text isEqualToString:#"\n"])
{
[textView resignFirstResponder];
return NO;
}
return YES;
}
Enjoy Buddy with this code....
I'm using UISearchBar in my application and it serves as both an edit field as well as a search. So when I want to disappear the keyboard I have to use cancel button in UISearchBar but I can't have that cancel button on screen, so how could T make keyboard disappear when not used without using cancel button. Please help me as i'm new to iPhone application development.
Thanks in advance!
Use this:
[UISearchBar resignFirstResponder];
Just replace the word UISearchBar with the name of the object you have created.
Are you looking for ways you can dismiss the keyboard or how to actually do that programmatically? If programmatically, then [UISearchBar resignFirstResponder]. If you are looking for a possible way for the user to achieve that you can either make the return button on the keyboard resign its first responder status when pressed, or attach a UIGestureRecognizer to your view and set it up so that when the user clicks outside the keyboard, this keyboard goes away.
simply all you need to do is to get UITextfield control from the UISearchbar and then set UITextfield's delegate to whatever delegate that will perform -(void) textFieldShouldReturn:(UITextField *)textField
-(void)viewDidLoad{
UIView * subView;
NSArray * subViews = [searchbar subviews];
for(subView in subViews)
{
if( [subView isKindOfClass:[UITextField class]] )
{
((UITextField*)subView).delegate=self;
((UITextField*)subView).returnKeyType=UIReturnKeyDone;
break;
}
}
}
-(BOOL) textFieldShouldReturn:(UITextField *)textField{
[textField resignFirstResponder];
return TRUE;
}
I have one view name:myplay.h and myplay.m
my view contain one textfield name txtplay..
It contain one button name btnplay.
In button event i want to check that if uikeyboard is open then close it.
I know below code
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return TRUE;
}
and in button click event
-(IBAction)btnplayclick:(id)sender
{
[self.txtplay resignFirstResponder];
....
....
}
I want a global code to resign.
Try this:
[self.view endEditing:YES];
From the doc:
endEditing:
Causes the view (or one of its embedded text fields) to resign the first responder status.
(BOOL)endEditing:(BOOL)force
This method looks at the current view and its subview hierarchy for the text field that is currently the first responder. If it finds one, it asks that text field to resign as first responder. If the force parameter is set to YES, the text field is never even asked; it is forced to resign.
Available in iOS 2.0 and later.
The best way i think to be generic and reuse your code anywhere is to create a category for the UIView :
#implementation UIView (FindFirstResponder)
- (UIView *)findFirstResonder
{
if (self.isFirstResponder) {
return self;
}
for (UIView *subView in self.subviews) {
UIView *firstResponder = [subView findFirstResonder];
if (firstResponder != nil) {
return firstResponder;
}
}
return nil;
}
#end
And then to call the method like that :
-(IBAction)btnplayclick:(id)sender
{
UIView *firstResponder = [self.view findFirstResonder];
[firstResponder resignFirstResponder];
}
It does the tricks perfectly for me.
or just write
[self.view findAndResignFirstResponder];
Calling resignFirstResponder on a UITextField that ISN'T first responder is a harmless no-op.
So go:
for (UIView *candidate in self.subview) {
if ([candidate isKindOfClass:[UITextView class]]) {
[(UITextView *)candidate resignFirstResponder];
}
}
I'm wondering if there is a way to have the UITextField clear button 'always visible'
textfield.clearButtonMode = UITextFieldViewModeAlways;
doesn't seem to work
.. and if it is possible to dismiss the keyboard using the button?
Thanks in advance.
Like mentioned before it seems apple is setting the textfield focus after you clear the field.
The solution is quite simple. Just clear the field yourself, resignFirstResponder and return NO
-(BOOL)textFieldShouldClear:(UITextField *)textField
{
textField.text = #"";
[textField resignFirstResponder];
return NO;
}
In your delegate, the function
- (BOOL)textFieldShouldClear:(UITextField *)textField
is called when the users wants to clear the textfield. If you return YES and call
[textField resignFirstResponder];
the keyboard should go away. I don't know about the clearButtonMode, other than that you may want to set it early, preferably before adding the view to its superview.
edit To make sure you really resign the responder, try doing it just a little later:
[textField performSelector:#selector(resignFirstResponder) withObject:nil afterDelay:0.1];
The delay didn't work well for me. Instead I added an instance variable to the delegate:
BOOL cancelEdit;
Then in the delegate implementation:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
if (cancelEdit) {
cancelEdit = NO;
return NO;
} else {
return YES;
}
}
- (BOOL)textFieldShouldClear:(UITextField *)textField
{
cancelEdit = YES;
return YES;
}
UITextFieldDelegate textFieldShouldClear
- (BOOL)textFieldShouldClear:(UITextField *)textField {
[textField] resignFirstResponder];
return YES;
http://developer.apple.com/iphone/library/documentation/uikit/reference/UITextFieldDelegate_Protocol/UITextFieldDelegate/UITextFieldDelegate.html#//apple_ref/occ/intfm/UITextFieldDelegate/textFieldShouldClear:
I discovered this odd behavior was caused by a competing gesture recognizer that resigned the first responder before the keyboard before textFieldShouldClear: was called. It seemed to be corrupting the first responder.
If you've set it up this way, ensure that cancelsTouchesInView on your gesture recognizer is set to YES. This way you shouldn't need to do anything special in the textFieldShouldClear: or textFieldShouldBeginEditing: delegate methods.
