Question

I’m fairly new to iPhone programming, and I’m making a fairly basic app. Anyway, I just want to know how to go about creating a menu that scrolls up from the bottom (beginning at the top of the tab bar) that displays a few options. I’ve attached a picture that better helps portray what I mean. I’m assuming I should create some sort of subview and then add some animation to it, but I’d like to get your advice on the best way to start.
Thanks

The simplest solution would be to use a UIActionSheet, unmodified.

If that’s not what you’re looking for, using a modal view controller is always an option.

If, however, you want something that won’t cover the entire screen, and can have a custom look, the basic idea is this:

1. Create your view with a frame that’s just at the bottom of your main view (e.g. at 0,406).
2. Optionally disable user interaction with the main view
3. Use UIView animations to move it up

The code would look something like this:

UIView *customView = [[UIView alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height, self.view.bounds.size.width, kCustomViewHeight)];
[self.view addSubview:customView];

[UIView animateWithDuration:0.2 animations:^{
  CGRect f = customView.frame;
  f.origin.y -= kCustomViewHeight;
  customView.frame = f;
}];
