Answer 1

I believe what you want here is a collapsible UITableView, apple has a great example here:

Table view updates

Otherwise all you need to do is modify the frame inside the method in this block like this:

 [UIView animateWithDuration:1.0 animations:^{
                    myView.frame = newFrame
                }];

Hope that helps.

Answer 2

You can do something like this:

when the down button is pressed for profile view, then do something like this:

[UIView animateWithDuration:1 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
        [profileView setFrame:CGRectMake(profileView.frame.origin.x, profileView.frame.origin.y, profile.frame.size.width, finalHeight)];
        [settingsView setFrame:CGRectOffset(settingsView.frame, 0, final_Y_Coordinate)];

    }completion:^(BOOL finished){
    }];

So what this basically, do is, it increases the height of profile view and simultaneously change Y-Coordinate of Settings View.

You can do same thing for settingsView where only height of settingsView changes.

Hope it helps!
