`

it's better create container view controller manages view controllers. example, in viewdidload: of container controller add current controller:

[self addchildviewcontroller:self.currentviewcontroller]; [self.currentviewcontroller didmovetoparentviewcontroller:self]; [self.view addsubview:self.currentviewcontroller.view]; //here set currentviewcontroller view's frame or constraints if needed 

when need open login controller, this:

[self addchildviewcontroller:loginviewcontroller]; [self.loginviewcontroller didmovetoparentviewcontroller:self]; [self.view addsubview:loginviewcontroller.view]; //here set loginviewcontroller view's frame or constraints if needed  //then remove current view controller [self.currentviewcontroller willmovetoparentviewcontroller:nil]; [self.currentviewcontroller removefromparentviewcontroller]; [self.currentviewcontroller.view removefromsuperview];
