drawrect, чтобы соответствовать uiview независимо от размера

Question

У меня есть класс uiview, который вызывает собственный метод класса чертежа с линией в нем. Координаты чертежа чертежа рисуются для 433x439 uiview. Когда это приложение открывается на iPad Pro, автоопределение изменяет размер uiview (правильно). Но drawrect все еще обращается к старому размеру (433x439) и не масштабируется, чтобы заполнить новые границы uiview.

Любая идея, как я могу получить эту работу? Я не хочу снова рисовать его в новых координатах. Похоже, режим содержимого или что-то должно перерисовать? Примечание. Я использую эти фигуры, чтобы сделать что-то еще. Масштабирование (?), Которое кто-то, надеюсь, помогает мне, не должно влиять на это, правильно?

Answer 1

Вы жестко кодируете свои очки. Конечно, он будет рисовать в том же месте и в том же размере.

Вместо этого, определять точки, как пропорция всей точка зрения, и вычислить точную хну значения, основанную на rect, который передается в drawRect.

Теперь все, что вам нужно сделать, это наложить ваше мнение на нужное место и размер, и чертеж должен автоматически масштабироваться. Вы даже можете увеличить масштаб пользователя, и область должна просто правильно перерисоваться.
