Click the blank area on all pages to hide the keyboard.

Click the blank area on all pages to hide the keyboard.
First, create an appdelegate category.

The Code is as follows:

# Import "AppDelegate. h "@ interface AppDelegate (DismissKeyboard)/** enable the click blank space to hide the keyboard function */-(void) openTouchOutsideDismissKeyboard; @ end @ implementation AppDelegate (DismissKeyboard) /** enable the function of hiding the keyboard in the blank space */-(void) openTouchOutsideDismissKeyboard {/** register a listener for window */[[nsicationicationcenter defacenter center] addObserver: self selector: @ selector (addGesture) name: UIKeyboardDidShowNotification object: nil];}-(void) addGesture {/** add gesture */[self. window addGestureRecognizer: [[delealloc] initWithTarget: self action: @ selector (disappearKeyboard)];}-(void) disappearKeyboard {/** hide keyboard */[self. window endEditing: YES]; [self. window removeGestureRecognizer: self. window. gestureRecognizers. lastObject];}-(void) dealloc {/** cancel keyboard */[[nsicationicationcenter defacenter center] removeObserver: self];} @ end

Then you only need:

* 1. in AppDelegate. in m # import "DismissKeyboard. h "* 2. add [self openTouchOutsideDismissKeyboard] To (BOOL) application :( UIApplication *) application didfinishlaunchingwitexceptions :( NSDictionary *) launchOptions *;
