Michael Tsai - Blog - Xcode 11.2 and XIBs With UITextView
Как сделать UIScrollView, который будет увеличиваться до размеров контента?
Создадим пустой проект с шаблоном “Single View Application”.
Добавим ScrollView и зададим отступы ко всем краям экрана.
Внутрь ScrollView кладем просто View и зададим отступы со всех сторон к родительскому элементу,
после это InterfaceBuilder подсветит только что добавленную View красным цветом и выдаст ошибку:
(Need constraints for: X position or width, Need constraints for: Y position or height).
Зажимаем Ctrl и мышью тянем от contentView к ScrollView, добавляем два constraint’a: Equal Heights и Equal Widths.
Выделяем constraint Equal Heights и устанавливаем ему приоритет Low (250).
Авто-расширяющийся ScrollView готов!
Необходимым условием является то что лежащие в нем элементы все должны иметь вертикальные constraint’ы, отталкивая друг от друга по вертикали они в случае необходимости расширят View лежащую в ScrollView.
Проверим работоспособность:
Добавим во contentView три UILabel,
Answer UILabel установим свойство Lines = 0 и Line Breaks = Word Wrap, для того чтобы UILabel сам разбил длинный текст на строки и делал переносы только целыми словами.
А вот теперь важный момент: от Answer UILabel протягиваем constraint к самому нижнему UILabel:
устанавливаем Constant = 8 и Relation = Greater Than or Equal.
Результат.
Если контента будет мало то:
а если контента будет много:
