The full-on way to do this in iOS 7 is with an interactive custom transition. You will use a UIScreenEdgePanGestureRecognizer and respond to the drag gesture from the edge of the screen by performing part of the transition animation to match the distance the user's finger has travelled. Look into the UIPercentDrivenInteractiveTransition class to help you do that.

Here's a complete example you can download and run: it happens that I'm doing it from the left or right, not the top or bottom, but it is the same basic idea.

https://github.com/mattneub/Programming-iOS-Book-Examples/blob/master/bk2ch06p296customAnimation2/ch19p620customAnimation1/AppDelegate.m

But beware: if you try to do it from the top or the bottom you will get interference from the notification center (top) and the control center (bottom). It can be tricky to prevent that interference.

Hi you can use it.

- (void)showShareView {

    [self.view bringSubviewToFront:self.view_Email];

    [UIView beginAnimations:@"Show"
                    context:nil];
    [UIView setAnimationDuration:0.3F];

    CGRect frame = self.view_Email.frame;

    if (IS_IPHONE5) {
        if(txtFieldActiveFlag==1){
            frame.origin.y = 568-420;
        }else{
            frame.origin.y = 568-220;
        }
    } else {
        frame.origin.y = 480 - 275 - 88;
    }

    self.view_Email.frame = frame;
    [UIView commitAnimations];
}

- (void)hideShareView {

    [UIView beginAnimations:@"Show"
                    context:nil];
    [UIView setAnimationDuration:0.3F];

    CGRect frame = self.view_Email.frame;

    if (IS_IPHONE5) {

        if(txtFieldActiveFlag==2){
            frame.origin.y = 568-220;
        }else{
            frame.origin.y = 568;
        }
    } else {
        frame.origin.y = 480;
    }
    self.view_Email.frame = frame;
    [UIView commitAnimations];
}


//call method from any button action.

 [self showShareView]; //show the view up

 [self hideShareView]; //show the view down

Thanks
