title: Loop through text fields array and check if ALL are empty
body: <p>Im looping through an array of <code>UITextFields</code> and checking if any of them are empty</p>
  
  <pre><code>NSArray*textFields = ...;
  
  
  textFieldHasData = YES;
  [textFields enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
      if ([obj isEqualToString:@""]) {
          textFieldHasData = NO;
          *stop = YES;
      }
  }];
  if (!textFieldHasData) {
      //Empty text fields found
  }
  </code></pre>
  
  <p>I also want to check if <strong>ALL</strong> the <code>textfields</code> are empty in the array,  rather than individually.</p>
