Answer 1

Instead of setting hidden property of your loginview, set its alpha to 0.0 and you can use this animation
-(IBAction)Regbtn_click:(id)sender {
//[self.view addSubview:self.loginView]; if your loginview is not added to view, if it is, ignore this line
[UIView animateWithDuration:0.5 animations:^{
self.loginView.alpha = 1.0; //to display loginview
} completion:^(BOOL finished) {
}];
}

Answer 2

You can animate the view with two animations:
1) scaling
2) fading
View Controller
->Button (Viewcontroller Child)
->LoginWrapperView (Viewcontroller Child)
->black-transparent View (LoginWrapperView Child)
->login View (LoginWrapperView Child)
Add black semi-transparent view (with opacity of 0.2 i think) on screen and above that place your loginView and set its opacity to 0.
[LoginWrapperView SetHidden:YES];
[loginView SetAlpha:0];
[loginView SetFrame:CGRectMake(0,0,0,0)];
Now when you click on the button,
[LoginWrapperView SetHidden:NO];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.2];
[UIView setAnimationDelegate:self];
//position on screen
[loginView SetAlpha:1];
[loginView SetFrame:<your CGRect goes here>];
[UIView setAnimationDidStopSelector:#selector(finishAnimation:finished:context:)];
//animate off screen
[UIView commitAnimations];
Then handle Tap Getsture on semi-transparent view to close or hide the same by reversing the same animation with different values.

You can push your view modally or use a nice library like MZFormSheetController that do just that.
Here's how it looks like
It is simple just present your view. You could also make the background transparent and many other customization.
YourPopupViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:#"PopupView"];
-(IBAction)buttonClick{
// present form sheet with view controller
[self mz_presentFormSheetController:vc animated:YES completionHandler:^(MZFormSheetController *formSheetController) {
//do your login stuff
}];
}
