I got a simple detail view with a textfield.
In detail's viewController I wrote this code:
- (void) viewDidAppear:(BOOL)animated{
[self.textField becomeFirstResponder];
NSLog(#"is textField 1st responder %d", [self.textField isFirstResponder]);
}
When I push the detail into a navigation controller, I see "is textField 1st responder 0" in my log.
The keyboard doesn't appear.
But the textfield has blinking cursor.
What happens in this moment? Why the keyboard doesn't appears? I did try to catch a notification "KeyboardDidShown" in my AppDelegate but didn't catch anything:
Here is my master view design :
Does calling reloadInputViews help?

There are multiple textfields in a viewcontroller in which some of them are customised (one tapping those textfield will launch a popover controller, from that user can select the option which will get displayed in tapped textfield).
I have a tap gesture on the view controller for dismissing the keyboard (if it's on the screen).
Keypad gets locked(if it's visible) when I open the popover controller on taping the customised textfield. The keyboard is not getting dismissed even if I tap on the parent view or else on the dismiss button in the keypad.
I have tried this 2 snippets to hide the keyboard, but it's not working
[self.scrollView endEditing:YES];
[[[UIApplication sharedApplication] keyWindow] endEditing:YES];
You can use textfields delegate to prevent it from presenting a keyboard and instead present popover yourself by implementing this textFieldShouldBeginEditing method
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
if(textField == myCustomTextField) {
[self openCustomPopover];
return NO;
}
return YES;
}
more on its delegate methods here https://developer.apple.com/library/ios/documentation/UIKit/Reference/UITextFieldDelegate_Protocol/index.html#//apple_ref/occ/intfm/UITextFieldDelegate/textFieldShouldBeginEditing:
The following code used to work in iOS6 to hide the keyboard when a view controller was popped off of the navigation stack:
- (void)viewWillDisappear:(BOOL)animated {
[self.view endEditing:YES];
[super viewWillDisappear:animated];
}
However, in iOS7, the [self.view endEditing:YES] line seems to get ignored. I tried the command in other view events (viewDidDisappear, viewWillAppear, and viewDidAppear), and the only one it worked in is viewDidAppear. It seems that once a "pop" is initiated, we lose the ability to hide the keyboard until the view controller is "pushed" back on the stack.
While placing the code in viewDidAppear does work to hide the keyboard, the bad thing is that the keyboard is displayed briefly when the viewController is pushed back on to the navigation stack...pretty unacceptable from a UI perspective.
Has anyone else had success in working around this issue? I would prefer not to have to write my own CANCEL button, but right now, that is the only thing I can think of that will work.
If it's a UITextView set the editable property to NO. I tried this and it hides the keyboard as soon as it's set. I haven't tried it with a UITextField but I'm guessing you'd get the same result with setting the enabled property to NO. If that doesn't work, create a UITextField with userInteractionEnabled set to NO as a background for a transparent UITextView and use the editable property as stated above.
There was a change in iOS 7 where view controllers that are presented as modal forms cannot dismiss the keyboard by default. To fix this, you need to override your view controller's disablesAutomaticKeyboardDismissal method and return NO.
The problem is that somewhere between the time I press the "BACK" button and the time that viewWillDisappear fires, the current text field's canResignFirstResponder is getting set to FALSE, which is preventing the keyboard from hiding. I have not been able to discover anything in my code which could cause this, and I strongly suspect that it could be some kind of iOS 7 bug, as the same code worked for me under iOS 6.
As a workaround, I implemented the following solution. I subclassed UINavigationController and overrode the following method:
- (UIViewController *)popViewControllerAnimated:(BOOL)animated {
[self.topViewController.view endEditing:YES];
return [super popViewControllerAnimated:animated];
}
This caused the keyboard to appropriately disappear when I tapped the Back button to pop the current view controller. Nice sigh of relief that I didn't have to write a bunch of custom Back buttons.
To hide the keyboard when the text field lost focus
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
if ([textField isFirstResponder])
[textField resignFirstResponder];
return YES;
}
I tried a workaround. It may not be what you guys are expecting.
If you are using storyboard, You can resign the keyboard in "prepareForSeuge" method.
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
[self.view endEditing:YES];
}
It worked fine for me.
Approach given in the below will definitely hide the status bar in iOS7.
- (BOOL)prefersStatusBarHidden
{
return YES;
}
Add this to your .plist file (go to 'info' in your application settings)
View controller-based status bar appearance --- NO
Then you can call this line to hide the status bar:
[[UIApplication sharedApplication] setStatusBarHidden:YES];
In case your app is developed to support iPhone only, status bar won't hide when you run your app in iPad.
Put your UItextfield or UItextview for global declaration.
UITextfield textfield = your textfield object;
-(void)viewWillDisappear:(BOOL)animated
{
[self.view endEditing:YES];
[textfield resignFirstResponder];
[super viewWillDisappear:animated];
}
So i am making an app and am having some problems with dismissing the keyboard from UISearchBar and UITextFields. Here is the structure of my app:
NavigationController -> ViewC1 - (Modally)-> ViewC2 -(Modally) -> ViewC3
I have a search box in ViewC1, and when the "Search" button on the keyboard is pressed the keyboard is dismissed, this works fine. However if i return to ViewC1 after being in ViewC3 the keyboard no longer dismisses when the "Search" button is pressed. In the search bar delegate method i have put as follows:
- (void) searchBarSearchButtonClicked:(UISearchBar *)search
{
if ([search isFirstResponder]) {
[search resignFirstResponder];
} else {
[search becomeFirstResponder];
[search resignFirstResponder];
}
}
This does not solve the problem and i am not sure why the keyboard is not dismissing. For reference, when returning to the original ViewC1, ViewC3 is dismissed as follows:
UIViewController *parent = self.presentingViewController;
[parent.presentingViewController dismissViewControllerAnimated:YES completion:nil];
Any help is appreciated, thanks.
Okay i figured out what the problem was. They first responder was being resigned but the keyboard was not disappearing because of a focus issue. There is a default behaviour on modal views to not dismiss the keyboard (which is not a bug apparently). So after returning from the modal view it was still having this behaviour (resigning first responder but not dismissing keyboard). The way i solved this was by placing the following code in both the modal views .m files:
- (BOOL)disablesAutomaticKeyboardDismissal {
return NO;
}
This solved it for me. Then by either using:
[search resignFirstResponder];
or
[self.view endEditing: YES];
The keyboard will dismiss fine!
You'll need to do some debugging with break points to figure out why that conditional statement is not being hit. You could also use the endEditing method in UIView to simply resign the responder whenever search is clicked:
- (void) searchBarSearchButtonClicked:(UISearchBar *)search
[search endEditing:YES];
}
http://developer.apple.com/library/ios/#documentation/UIKit/Reference/UIView_Class/UIView/UIView.html
Try it....
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
[mySearchBar resignFirstResponder];
}
Please declare IBOutlet UISearchBar *mySearchBar; in your .h file
Set delegate in your .xib file.
Hope this helped

I've just had the same problem with my iPad app.
I had a"Please register" UIView containing a few UITextFields which I would pop onto the screen. When the user tapped on a Close button, it'd disappear, and I'd use removeFromParentViewController to get rid of it.
[self.pleaseRegisterDlg removeFromParentViewController];
Now, when I ran this code on a real device in debugging mode from XCode, the story ended there. It all worked fine. But when I built an In-House app with this code, it behaved differently.
I would find that sometimes, no matter how many resignFirstResponders or disablesAutomaticKeyboardDismissals I put into the code, there would be times when the onscreen keyboard would suddenly appear, and refuse to go away programatically.
It made no sense, as the rest of my app didn't have any UITextFields... there was no reason for the app to display a keyboard.
My solution was to set the "Please Register" UIView to nil after removing it from the parent view.
[self.pleaseRegisterDlg removeFromParentViewController];
pleaseRegisterDlg = nil;
Apparently, having a UIView which isn't actually attached to any other UIViews but which contains UITextFields is sometimes enough to confuse iOS, and make the onscreen keyboard appear.
(Sigh. This one line of code wasted a few hours of my afternoon.. lesson learned !)
I want to resign first responder from the currently edited textfield when a row is selected in the UITableView and a push segue is triggered inside a navigation controller. This is happening within a popover.
I've tried two things:
(1) I can see that the textfield is resigning the first responder while animating, but then when I go back to the view controller it takes first responder again and shows the keyboard.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self.view endEditing:YES];
}
(2) This will prevent the restoring of the editing when going back to the view controller, but this method breaks the animation. In the end of the animation, the first view controller gets black and it jumps a little bit.
EDIT: Just realized that this is only visible in landscape mode as it has something to do with that the keyboard animates faster than the push animation, and it gets black as soon as the keyboard is gone and the popover starts to animate to a higher height when the keyboard leaves room for it. The animation can't handle expanding the popover while animating the push animation in the navigation controller. When removing the code below and pushing and letting iOS remove the keyboard, the keyboard and push animation is taken exactly the same time and avoiding this issue. I wonder how I can make that happen myself while forcing the resignation.
- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self.view endEditing:YES];
return indexPath;
}
How can I resign first responder when changing view controller without it restoring the first responder on the text field again when navigating back?
Hold on a minute. So the issue is that when you perform the segue (and dismiss the view) when the view restores it has a sort of shadow of the keyboard showing. Is that it? In that case. You could try the following. when you click the tableviewcell. Do a check. like the following.
if(firstResponder != nil){
//register for keyboard hide notification
[[NSSnotificationCenter defaultCenter] addObserver:self selector:#selector(keyboardDidHide:) name:#"UIKeyboardDidHideNotification" object:nil];.
[firstResponder resignFirstResponder];
} else {
[self performSegue:#"yoursegueidentifier" withSender:nil];
}
That will only launch the segue if there is not a responder (and hence, not a keyboard). If there is a keyboard, it registers for the keyboard hide notification, and then resigns the responder. Then, in the method that responde to the keyboard hiding
- (void)keyboardDidHide:(NSNotification *)notification {
[self performSegue:#"yoursegueidentifier" withSender:nil];
}
This should only perform the segue when the keyboard has hidden, so it should resolve the animation issue. You may need to modify your storyboard to have the segue launch from the view controller and not from the cell's button, I'm not sure about how your architecture is. let me know if this works or not.
I have UIView with few UITextFields. On load I call [textfield becomeFirstResponder] to bring keyboard on the screen. I don't want to dismiss this keyboard until I done with view.
Keyboard dissapear after I "touch" outside any textfield.
I tried to set
- (BOOL)textFieldShouldEndEditing:(UITextField *)textField
{
return NO;
}
however then I can't dismiss keyboard even after is unloaded.
Any hints how to keep keyboard all the time and dissmiss it just before uiview remove?
When viewWillDisappear (or viewDidDisappear) is called, then call resignFirstResponder on your UITextField.
- (void) viewWillDisappear:(BOOL) animated {
[self.textField resignFirstResponder];
}
call this line before dismiss.
view.endEditing(true)
