title: android.graphics.Bitmap on iOS
body: <p>I'm migrating an Android application to iOS.</p>
  
  <p>On Android I have an <code>android.graphics.Bitmap</code> object and I don't know which object can I use on iOS.</p>
  
  <p>I thought I can use <code>CGBitmapContext</code> or <code>UIImage</code>. And on the book Learn Objective-C for Java Developers, I haven't found anything useful.</p>
  
  <p>On Android, first I have to created with a <code>size</code>, that I can use this <code>Bitmap</code> to get a JPEG version of it or I can draw some pixels on it.</p>
  
  <p><strong>What do you recommend me?</strong></p>
