ios - Navigate Back to previous view controller -


i have uiview->uicollectionview->uicollectionviewcell. trying navigate programatically none of these works. code did called. using storyboard.

- (void) goback:(nsnotification *) notification {       // [self.navigationcontroller popviewcontrolleranimated:yes];      //  [self dismissviewcontrolleranimated:yes completion:nil];       [self.navigationcontroller poptorootviewcontrolleranimated:yes]; }

you need use:

[self.navigationcontroller poptorootviewcontrolleranimated:yes];

this bring root view controller.

if want navigate previous view controller, should implement: 

[self.navigationcontroller popviewcontrolleranimated:yes];
