SWRevealViewController dismiss keyboard on swipe
Problem is the same but this answers does not help me.
There are some solutions in the given link.For example I don't have any #if macros to delete and I get an error when I write revealController.delegate = self; in AppDelegate.m
And the delegate method below never get called.
- (void)revealController:(SWRevealViewController *)revealController didMoveToPosition:(FrontViewPosition)position
{
//Never get called
}
I searched the Internet and did everything mentioned in the given link.
I am using SWRevealViewController V 1.1.3 https://github.com/John-Lluch/SWRevealViewController/releases
The problem is: I have a UITextField inside a ViewController which behaves as a Front View.When I click on UITextField, keyboard shows up, then I swipe to see my ViewController which behaves as Rear View but keyboard is still there and I can't hide it.
How can I make it possible?
I tried using willMove to position.........However it displays the keyboard when the Rear View controller pops up soon after the keyboard gets hidden..........
For me this worked perfectly....
func revealControllerPanGestureShouldBegin(revealController: SWRevealViewController!) -> Bool {
self.view.endEditing(true)
return true
}

I'm having a weird reaction in 1 of my view when swipe to back.
It did not go back to my previous page but other pages does not have this issue. Also, it perform the previous page viewWillAppear code after the swipe.
I did not set any custom back buttons for the views but it is having different effect.
--Edit--
In my previous page that call the affecting page
ViewControllerA *view = [[ViewControllerA alloc] initWithNibName:#"ViewControllerA" bundle:nil];
[self.navigationController pushViewController:view animated:YES];
In my affecting page I only declare viewDidLoad function.
All my navigation for other classes is using the above calling.
By normal clicking the back action at the navigation bar, it will go back to the previous page normally.
--Edit 2--
My current setup is ViewA > ViewB > ViewC where ViewC is where the bug is happening.
At ViewB when I swipe at the edge, it can go back to ViewA.
At ViewC when I swipe at the edge, viewWillAppear in ViewB called but ViewB is not shown.
Tried putting #kaushal answer
if ([self respondsToSelector:#selector(interactivePopGestureRecognizer)]) {
self.navigationController.interactivePopGestureRecognizer.enabled = YES;
self.navigationController.interactivePopGestureRecognizer.delegate; //check UIGestureRecognizerDelegate delegate set properly.
}
in both ViewB and ViewC but it did not trigger.
--Edit 3--
I tested my other features flow and it seems that some have this same problem upon entering the third view and some is on the forth view.
In ViewDidAppear: use this code :
if ([self respondsToSelector:#selector(interactivePopGestureRecognizer)]) {
self.navigationController.interactivePopGestureRecognizer.enabled = YES;
self.navigationController.interactivePopGestureRecognizer.delegate; //check UIGestureRecognizerDelegate delegate set properly.
}
And check UIGestureRecognizerDelegate is not nil.
I have a problem with a GLKViewController (subclass) used in a Storyboard: it refuses to handle tap events.
I added a Tap Gesture Recognizer to the GLKViewController (subclass) in the Storyboard and linked it to a 'tapDetected' method:
- (IBAction) tapDetected:(id)sender {
NSLog(#"tap\n");
[self.navigationController setNavigationBarHidden: ![self.navigationController isNavigationBarHidden]];
} // tapDetected
This exactly how I manage - successfully - the taps in other view controllers in the same Storyboard. Only the GLKViewController does not receive the event: neither the log nor the navigation bar are affected by the tap.
I searched for any specific need of GLKViewControllers but could not find any. Do you have any idea and/or suggestion?
It looks like if I add a touchesBegan method everything works ok. So the question is: what's the point of the gesture recognizer in the Storyboard?
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 !)
Hi there, Now I'm trying to create a Pop-OverView using an Xcode
storyboard. Firstly, I have
rootViewController, UIViewController, and UITableViewController
I want the UIView to act as a page flip and the UITableView will show popOver under the navigationBar item controller.
For the UITableView, I want to make a Pop-Over under NavigationBar controller. The problem is, when I touch the Navigation item to show the UITableViewController, it shows correctly, but when I try to close the Pop-Over View, it won't close. And then, the navigation item doesn't work well. It shows multiple instances of popOverView when I touch it multiple times.
This doesn't seem to make sense to me. Can anyone help me out or tell me where to find documentation / tutorials on this?
UPDATE:
For the UIPopOverController, it seems to work well now, but it is still bugging me when I touch a Navigation Item multiple times. It will show multiple instances of PopOver. How can I handle it, so it will show only one instance?
I had the same problem and mostly found the solution here. Basically you change the action of the button each time it's pressed to either display or dismiss the popover. Here's the code I ended up with:
#interface FilterTableViewController : UITableViewController {
UIPopoverController *editPopover;
id saveEditSender;
id saveEditTarget;
SEL saveEditAction;
}
-(void)prepareForSegue:(UIStoryboardPopoverSegue *)segue sender:(id)sender{
if([[segue identifier] isEqualToString:#"EditFilterSegue"]){
// Save the edit button's info so we can restore it
saveEditAction = [sender action];
saveEditTarget = [sender target];
saveEditSender = sender;
// Change the edit button's target to us, and its action to dismiss the popover
[sender setAction:#selector(dismissPopover:)];
[sender setTarget:self];
// Save the popover controller and set ourselves as the its delegate so we can
// restore the button action when this popover is dismissed (this happens when the popover
// is dismissed by tapping outside the view, not by tapping the edit button again)
editPopover = [(UIStoryboardPopoverSegue *)segue popoverController];
editPopover.delegate = (id <UIPopoverControllerDelegate>)self;
}
}
-(void)dismissPopover:(id)sender
{
// Restore the buttons actions before we dismiss the popover
[saveEditSender setAction:saveEditAction];
[saveEditSender setTarget:saveEditTarget];
[editPopover dismissPopoverAnimated:YES];
}
-(BOOL)popoverControllerShouldDismissPopover:(UIPopoverController *)popoverController
{
// A tap occurred outside of the popover.
// Restore the button actions before its dismissed.
[saveEditSender setAction:saveEditAction];
[saveEditSender setTarget:saveEditTarget];
return YES;
}
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
// Before we navigate away from this view (the back button was pressed)
// remove the edit popover (if it exists).
[self dismissPopover:saveEditSender];
}
