is it possible that as a user clicks on the text field(text field becomes the first responder), the placeholder animates upward. there is no need for the user to write text in the text field and then the placeholder animates upward.

研究方向
Examine the JVFloatLabeledTextField implementation to understand how the placeholder is currently displayed and animated. Focus on the method that handles becoming first responder (likely related to UITextField delegate or subclass). Consider implementing an animation that moves the placeholder upward when the text field gains focus, before any text is entered. Review existing comments and any linked discussions for potential solutions or constraints.
