Scroll View движется горизонтально, а не вертикально

Question

Я создал вид прокрутки и попробовал много разных методов, как вы можете видеть ниже, однако я всегда получаю один и тот же результат, когда вид прокрутки перемещается горизонтально. Я хочу, чтобы он двигался вертикально, но это не так. Кроме того, текстовое представление показывает все сообщение в одной строке и не использует несколько строк, как это было до того, как я добавил представление прокрутки.

Вы должны проверить свои ограничения и убедиться, что ваше представление прокрутки имеет правильный contentSize .

Сделать левый и правый якоря scrollViewView также равными представлению viewController. В шутку c positionView ()
