Creating a Drawer - (iOS)

Question

I am making an iPad application, and basically, I want to make a tray that pulls out from the bottom of my application, and I would like to have a small tab at the bottom of the screen, which, if you pull it, it displays the image and the image height corresponds to the height that you clicked on the button. This is a bit like the notification center works, except that the tab is always visible.

So my question is, how should I make the image following the tab when it moves vertically across the screen? I would suggest that using the UIButton tab for the tab and UIImage for the tray makes sense, and I have code to move the buttons, but how can you make one object after another?

Thanks for your help, Carl

Answer 1

I would not use the button for the tab - just the usual old look.

To make your image behind a tab (no matter how you implement them), just animate them together. That is, if you create an animation that moves the center of the button to the Y-coordinate of the user touch, you can at the same time move the image vertically by the same amount. Then the two objects will be glued together because they move together.
