ios - Dismiss keyboard of UISearchBar with gesture recogniser after returning from modal views -

i have implemented uisearchbar application. have created programatically , using in view controller (not tableview). works fine, problem having using gesture recogniser dismiss keyboard. want keyboard dismissed when user taps screen outside of keyboard.

i know there lot of solutions out there solve problem, have rather unique problem can't figure out @ moment. have used next code implement this.

i placed line within viewdidload method of viewcontroller:

[self.view addgesturerecognizer:[[uitapgesturerecognizer alloc] initwithtarget:search action:@selector(resignfirstresponder)]];

this method works fine normally, view controller presents views modally, has next structure:

viewcontroller - modally -> view2 -modally -> view3

when view 2 , 3 dismissed , viewcontroller, gesture recogniser no longer works. have same problem when trying solution found:

uigesturerecognizer* cancelgesture; - (void) backgroundtouched:(id)sender { [self.view endediting:yes]; } #pragma mark - uisearchbardelegate -(void)searchbartextdidbeginediting:(uisearchbar *)search { cancelgesture = [uitapgesturerecognizer new]; [cancelgesture addtarget:self action:@selector(backgroundtouched:)]; [self.view addgesturerecognizer:cancelgesture]; } -(void)searchbartextdidendediting:(uisearchbar *)search { if (cancelgesture) { [self.view removegesturerecognizer:cancelgesture]; } }

i added these main viewcontroller , 1 time again worked fine start with, after returning modal views gesture no longer worked.

any help appreciated please!

edit 1:

so while testing found similar effect beingness had when pressing search button on keyboard. utilize next code dismiss keyboard 1 time search has been pressed:

- (void) searchbarsearchbuttonclicked:(uisearchbar *)search { [search resignfirstresponder]; }

same effect here, works fine when first start app , searching, after coming screen modally presented view controllers pressing come in no longer dismisses keyboard.

edit 2:

i tried adding piece of code in searchbarsearchbuttonclicked delegate method:

- (void) searchbarsearchbuttonclicked:(uisearchbar *)search { if ([search isfirstresponder]) { [search resignfirstresponder]; nslog(@"text field first responder"); } else { [search becomefirstresponder]; [search resignfirstresponder]; nslog(@"text field not first responder"); } }

and both times prints text field first responder. after returning modal views , clicking search bar 1 time again still says first responder not dismiss odd. insight helpful, thanks.

instead of adding , removing gestures in -(void)searchbartextdidbeginediting:(uisearchbar *)search { , -(void)searchbartextdidendediting:(uisearchbar *)search { in viewwillappear' (add here) andviewdiddisappear' (remove here).

and assuming cancelgesture property retain attribute. while adding gesture instead

uitapgesturerecognizer *gesture = [uitapgesturerecognizer new]; [gesture addtarget:self action:@selector(backgroundtouched:)]; self.cancelgesture = gesture; [self.view addgesturerecognizer:self.cancelgesture];

and remember release cancelgesture in dealloc.
