-(ibaction) BTNGOTOREGISTERVC: (UIButton *) Sender {SELF.REGISTERVC =[[registervc alloc]init
    ] ;//Initialize Registration Page view Controller
    [Self.registerVC.view setbackgroundcolor:[uicolor redcolor]];//Set the background color of the view for the registration page
    [Self.view addsubview:self.registervc.view];//The view on the login interface to add the registration interface
    self.registervc.view.center= Self.view.center;
} Adjust the alignment of a view

second, from the registration interface switch back to the landing interface

Switch from the registration interface back to the login interface
-(ibaction) Eventregister: (UIButton *) sender {
    [self.view Removefromsuperview];
    [Self Removefromparentviewcontroller];
}
