body: <p>How can I set the background color of a particular button in iPhone?</p>
  
  <p>I used:</p>
  
  <pre><code>btnName1 = [ColorfulButton buttonWithType:UIButtonTypeRoundedRect];
  btnName1.frame=CGRectMake(45,146,220,40);
  [btnName1 setTitle:@"Continue" forState:UIControlStateNormal]; 
  [btnName1 setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; 
  [btnName1 setImage:[UIImage imageNamed:@"green.png"] forState:UIControlStateNormal];
  UIImage *img =[UIImage imageWithContentsOfFile:[[NSBundle mainBundle]pathForResource:@"greenish" ofType:@"png"]];
  UIImage *strechableImage = [img stretchableImageWithLeftCapWidth:12 topCapHeight:0];
  [btnName1 setBackgroundImage:strechableImage forState:UIControlStateNormal];
  [btnName1 setNeedsDisplay];
  [InfoView addSubview:btnName1];
  </code></pre>
  
  <p>It's correctly working on iPhone simulator but not on iPod (color not shown in iPod).</p>
