iOS - Curved Rounded UITextfield

I need to have a textfield in my app that is curved, I am able to pre-define the path.

I have an textfield in my storyboard, and when a button is tapped, a text field needs to appear in, but curved.

How Do I achieve the curved part, making the textfield round and the text curve as it is entered?

thanks, Ari

You will need to write a hefty chunk of Core Text code + code to calculate curve geometry which essentially navigates your writing along a path.

Here are some good on/offline resources:
