title: How to create a translucent layer on click of button, which would slide up for iphone
body: <p>Hi I want to create a layer of the type in the image below.</p>
  
  <p><img src="https://i.stack.imgur.com/q54e9.png" alt="enter image description here"></p>
  
  <p>The layer (with Capture mode and Shutter speed) slides up when I click on the setting button. </p>
  
  <p>I am unable to figure out what should I do do create something like this. Also want to have the similar translucency in the layer as well as in the buttons on it also. </p>
  
  <p>On click on the same button again, the layer(with Capture mode and Shutter speed) disappears, leaving what was there on the screen before (the camera view and the lower bar with the camera capture button, and the two setting buttons)  </p>
  
  <p>Please any suggestions are much appreciated. </p>
  
  <p>Thanks </p>
