title: uiWebview call javascript function syntax
body: <p>I am migrating my app from android to iOS and for following line, compiler returns me an error on iOS,</p>
  
  <p><code>webviewA.loadUrl("javascript:setVars(\"" + var1 + "\",\""  + var2 +  "\")");</code> //properly executed on Android</p>
  
  <p>for iOS I am trying,</p>
  
  <pre><code>[webViewA stringByEvaluatingJavaScriptFromString:@"javascript:setVars(\"" + var1 + "\",\""  + var2 +  "\")"];
  </code></pre>
  
  <p>which would be correct syntax for iOS? Thank you.</p>
