SWRevealViewController dismiss keyboard on swipe

问题

I am using SWRevealViewController in my app and I am having a problem. I have a textfield in a scene, if I swipe left when the keyboard is open, the menu appears but it does not dismiss the keyboard. How do I dismiss keyboard on left swipe?

I have tried

UISwipeGestureRecognizer *swipe = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard)];
swipe.direction = UISwipeGestureRecognizerDirectionLeft;
[self.view addGestureRecognizer:swipeRecognizer];

-(void)dismissKeyboard
{
    [self.textField resignFirstResponder];
}

but it does not work, I think because I am already using a panGestureRecognizer for revealViewcontroller i.e. [self.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];

I am also using UITapGestureRecognizer but it only works for tap not for swipe.

回答1:

i think u need to use one of the delegate method in the app delegate there are so may delegate methods are there but u need do somthing like below

dont add any gestures

use this delegate in the appDelegate delete all the macros begins with #if don`t need that

put a break-point in app delegate to this method below delegate method celled each time SWRevealViewController moved or sliced ..

- (void)revealController:(SWRevealViewController *)revealController didMoveToPosition:(FrontViewPosition)position
{
   // NSLog( @"%@: %@", NSStringFromSelector(_cmd), [self stringFromFrontViewPosition:position]);
   if(position == FrontViewPositionRight) //check the where to move 
   {
      UINavigationController *viewController = revealController.frontViewController;

     if([viewController.visibleViewController isKindOfClass:[FrontViewController class]])
       {
         [(FrontViewController *)viewController.visibleViewController dismissKeyboard]; //where this is the method declared in the FrontViewController.h file
      }

   }
}

there is one warning still it works put break point and check hope this helps u ...

in FrontViewController.h

  -(void)dismissKeyboard; //add this

in the FrontViewController.m

 -(void)dismissKeyboard
 {
      if([self.textField isFirstResponder]) //check
         [self.textField resignFirstResponder];
 }

I had the same problem.

I added self.revealController.delegate = self; to my View Controller which I used as Front View.And delegate method get called.

I used - (void)revealController:(SWRevealViewController *)revealController willMoveToPosition:(FrontViewPosition)position{} delegate method and I wrote [textField endEditing:YES]; in this delegate method.

Also added <SWRevealViewControllerDelegate> to my ViewController.h which is my Front View.

回答3:

Try this:

Please add the below code in SWRevealViewContoller.m in the method -(BOOL)_panGestureShouldBegin

[self.view endEditing:YES];

回答4:

First of all you need to replace the revealToggle: method by your custom method like this:

UIBarButtonItem *barBtn = [[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@"reveal-icon.png"] style:UIBarButtonItemStyleBordered target:self action:@selector(myMethod)];

self.navigationItem.leftBarButtonItem = barBtn;

And than in your method:

-(void)myMethod{
[self.view endEditing:YES];
SWRevealViewController *reveal = self.revealViewController;
[reveal revealToggleAnimated:YES];
}

It will surely work.

回答5:

Try This

[[[self revealViewController] view] endEditing:YES]

Add this in

- (void)revealController:(SWRevealViewController *)revealController didMoveToPosition:(FrontViewPosition)position

or any other delegate method based on your requirement.

回答6:

check current position of frontview and write code of hiding keyboard in if condition.

回答7:

Are you sure that self.textField is the current first responder? If you are try to resign the first responder in the UIGestureRecognizer delegate's method – gestureRecognizerShouldBegin:

Obviously return YES in that function.

回答8:

Edit the below method in

SWRevealViewContoller.m

(IBAction)revealToggle:(id)sender {
    [self.view endEditing:YES];
    [self revealToggleAnimated:YES]; 
}
