ios - Source ViewController flashing after custom segue -

i trying make custom segue between 2 view controllers. works fine, except @ end of animation can see source viewcontroller flashing brief moment (very short). doesn't happen every time.

.h file:

#import <uikit/uikit.h>  @interface horizontalsegue : uistoryboardsegue  @property cgpoint originatingpoint;  @end 

.m file:

#import "horizontalsegue.h"  @implementation horizontalsegue  - (void)perform {     uiviewcontroller *sourceviewcontroller = self.sourceviewcontroller;     uiviewcontroller *destinationviewcontroller = self.destinationviewcontroller;      // add destination view subview, temporarily     [sourceviewcontroller.view addsubview:destinationviewcontroller.view];      // store original centre point of destination view     cgpoint originalcenter = destinationviewcontroller.view.center;      // set center start point of button     destinationviewcontroller.view.center = cgpointmake(self.originatingpoint.x*3, self.originatingpoint.y);      [uiview animatewithduration:0.5                           delay:0.0                         options:uiviewanimationoptioncurveeaseinout                      animations:^{                          destinationviewcontroller.view.center = originalcenter;                      }                      completion:^(bool finished){                          [destinationviewcontroller.view removefromsuperview]; // remove temp super view                          [sourceviewcontroller presentviewcontroller:destinationviewcontroller animated:no completion:null]; // present vc                      }]; }  @end 

is there way rid of flash? have tried of solutions presented similar problems, nothing works.

you not suppose show viewcontroller that, adding subviews of destination current 1 , making animatinos them. there lot of logic involved when transitioning 1 controller sdk needs do, important follow apple guides.

since ios7.0 there complete new way show controller animations via uiviewcontrollertransitioningdelegate (which @property of uiviewcontrollers) lets kind of animations.

there plenty of tutorials

if however, want keep old way of embedding controllers manually, should check "add , removing child" here: https://developer.apple.com/library/ios/featuredarticles/viewcontrollerpgforiphoneos/creatingcustomcontainerviewcontrollers/creatingcustomcontainerviewcontrollers.html
