I have a text field setup like so:

```
textField.borderStyle = UITextBorderStyleLine;
textField.layer.borderColor = [[UIColor greenColor] CGColor];
textField.layer.borderWidth= 10.0f;'

```

But is it possible to just have a larger border on the left side and it be a different color?
Or do I have to position a drawRect there with the color I want and position?
