title: iOS increase UIWebView font size
body: <p>I looked for solution on Stack Overflow but I didn't find one. My code is:</p>
  
  <pre><code>CGRect  rect = _postContentView.bounds;
  _postContentUIWV = [[UIWebView alloc] initWithFrame:rect];
  [_postContentUIWV loadHTMLString:selectedPostCD.content baseURL:nil];
  
  int fontSize = 30;
  NSString *jsString = [[NSString alloc] initWithFormat:
      @"document.getElementsByTagName('span')[0].style.webkitTextSizeAdjust='%d%%'",
      fontSize];
  [_postContentUIWV stringByEvaluatingJavaScriptFromString:jsString];
  
  [_postContentView addSubview:_postContentUIWV];
  </code></pre>
  
  <p>And the part of HTML inside <code>UIWebView</code>:</p>
  
  <pre><code>&lt;p style="text-align: justify;"&gt;
      &lt;span style="line-height: 1.5em;"&gt;blablablablablabla&lt;/span&gt;
  &lt;/p&gt;
  </code></pre>
  
  <p>My code doesn't increase the font size inside <code>UIWebView</code>. How can I solve it?</p>
