title: How should I slice buttons for ios development
body: <p>I'm going to slice a given image for iPhone developer. Since I'm a front-end developer and know that this button can be created using CSS in front-end development, I don't have any idea about how should I proceed. May I give PSDs directly to the developer or should it be sliced? If it should be sliced then how will it be? Here is the image:</p>
  
  <p><img src="https://i.stack.imgur.com/hLJAO.png" alt="Image to be sliced"></p>
  
  <p>Please note that this button has gradient, rounded corners and a little downward arrow. Forget the text inside for now.</p>
  
  <p>Have iPhone developers the ability to do that type of stuff using their code?</p>
  
  <p>If I should export those buttons (eliminating the text/icon inside), at what resolutions should that be?</p>
