title: How to create a round button?
body: <p>I want to create a round circular button. This button should look like  a circle.</p>
  
  <p>This code gives round rectangular button.</p>
  
  <pre><code>UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
  button.frame     = CGRectMake(100, 100, 100, 30);
  UIImage  *image  = [UIImage imageNamed:@"01.png"];
  [button setImage:image forState:UIControlStateNormal];
  [image release];
  </code></pre>
  
  <p>I figured out how to create a rounded rectangular button but I want to create a round circle button. What do I need to change?</p>
