ios - UITextField customization for how text is selected or inserted -

-

i'm planning work on small customization of uitextfield change ui/ux design features.

i know uitextfield has inbuilt methods change border style, color, etc. if wish make lot of customization, can guide me how should begin?

do need refer uitextfield parent class modify it? or have make custom ui object right scratch?

edit:

the customization plan on working how select/de-select or choose insertion point text in uitextfield.

it sounds you're going want take advantage of fact uitextfield adopts uitextinput protocol. can subclassing uitextfield. alternatively, might sufficient needs set other class delegate of uitextfield - depends on whether uitextfielddelegate notifies sufficiently fine grain user in text field.
