У меня есть вид на карту с несколькими аннотациями. В каждой аннотации есть кнопка, которая позволяет пользователю просмотреть подробный вид этой аннотации. В настоящее время в подробном представлении есть две метки: одна для названия из аннотации, а другая для подзаголовка аннотации и кнопка «Получить направления». Я хочу, чтобы метка заголовка была заполнена заголовком из аннотации и меткой субтитров для заполнения субтитрами из аннотации. Я хочу, чтобы кнопка Get Directions вводила пользователя в приложение «Карты» и давала им указания по адресу из своего текущего местоположения. Я также хотел бы добавить веб-сайт и номер телефона в подробный вид, но я не уверен, как заполнять эти поля. Детальный вид называется AnnotationDetailView, но я ничего не сделал с ним, кроме добавления кнопки и меток в IB. Я просто не знаю, как заполнить ярлыки и заставить кнопку делать то, что я хочу. Любая помощь будет большой.Открыть подробный вид из аннотации

Я имею пара вопросов с это. Во-первых, ярлык не появляется. Во-вторых, у меня есть инструкция NSLog в моем методе showDetails, чтобы показать мне, что такое marketAnnotations. Он показывает название последней добавленной аннотации.
