title: Convert first Letter of each word of a sentence to capital in iPhone
body: <p>I have the string:</p>
  
  <blockquote>
    <p>i am a bad boy.</p>
  </blockquote>
  
  <p>I want to convert that string into:</p>
  
  <blockquote>
    <p>I Am A Bad Boy.</p>
  </blockquote>
  
  <p>What I have tried only has worked for the first character of a word.</p>
