title: iOS: Is there a way to check if an NSArray object contains a certain character?
body: <p>I need a way to know if an array has the character "@" in one of its string objects. The following code obviously doesn't work because it checks if an object just has the @ sign instead of checking if an object contains the @ sign. For example, if the user has test@test.com my if statement won't detect it. I need to see if a user has an email or not. I tried researching on how to accomplish this on stackoverflow, but no luck. Any tips or suggestions will be appreciated.</p>
  
  <pre><code>if([answer containsObject:@"@"]){
    /// do function.                 
  }
  </code></pre>
