objective c - UIViewController Animation ios? -

trying create below in objective-c, available in swift. tried using bridging etc, use code objective c project it's having import issues.

in objective-c tried below things , partially works uiview, guess need add transitions complete uiviewcontroller.

what tried

- (ibaction)menubuttonpressed:(id)sender {     if ([self.delegate respondstoselector:@selector(menubuttonpressed)]) {         [self.delegate menubuttonpressed];     }     if (!isvertical) {         [uiview animatewithduration: 0.6                               delay: 0.0              usingspringwithdamping: 0.3               initialspringvelocity: .8                             options: 0                          animations: ^          {              self.transform = cgaffinetransformtranslate(self.transform, -240, 0);              self.transform = cgaffinetransformrotate(self.transform, 90 * m_pi / 180);              self.transform = cgaffinetransformtranslate(self.transform, 240, 0);          }                          completion:^(bool finished) {                              isvertical = yes;                           }          ];      }else{         [uiview animatewithduration: 0.45                               delay: 0.0              usingspringwithdamping: 0.44               initialspringvelocity: .8                             options: 0                          animations: ^          {              self.transform = cgaffinetransformtranslate(self.transform, -240, 0);              self.transform = cgaffinetransformrotate(self.transform, -90 * m_pi / 180);              self.transform = cgaffinetransformtranslate(self.transform, 240, 0);           }                          completion:^(bool finished) {                              isvertical = no;                           }          ];     } } 

any inputs helpful.

here simple implementation can use animate transitions between view controllers. use same animation gist if want use uiviews.
