Я приложил свой код для вашей справки. Я могу отображать данные в Pickerview при изменении строки, в которой данные изменяются соответствующим образом, но данные, выбранные из средства выбора, не отображаются в UITextfield
. если я выберу какую-либо опцию в Pickerview, я не смогу видеть текст внутри uitextfield
, если я выбрал его, все еще показывая пустое текстовое поле.
