UITextField "content size" property

Is there a way to make the right side of a UITextField's content "end sooner" like in this graphic:

I'm using the following to give the content text some left padding, but can't figure out an easy solution to reduce the available content size on the right size: self.textfield.layer.sublayerTransform = CATransform3DMakeTranslation(10, 0, 0);

I'd rather not subclass UITextField but I'm fine doing so if need be.
