Cocos2d и новый формат iPhone 5
Я только что видел анонс iPhone 5, в котором говорится, что разрешение в пикселях изменилось до 1136*640, что влияет на АСПЕКТНОЕ ОТНОШЕНИЕ приложения.
Как мне справиться с этим в моей игре Cocos2d? Я получил всю графику для "старого" экрана дисплея сетчатки 960*640, и я думаю, что она будет искажена на экране iPhone 5.
Я прав? Или будут отображаться изображения со "старым разрешением" без изменения соотношения сторон и сохранения черного экрана?
РЕДАКТИРОВАТЬ: Есть ли способ заставить Cocos2d определить, является ли это iPhone 5, и в этом случае нарисовать фоновые файлы в верхней части экрана (верхние 960 пикселей) и получить некоторые другие пользовательские фоновые файлы для рисования в оставшихся пикселях (например, это могут быть некоторые рекламные баннеры или дополнительные кнопки, доступные в нашей игре только для iPhone 5).

Решение
Я только что добавил 4-дюймовую поддержку в мое приложение этим утром. Cocos2d работает нормально (в симуляторе) без изменений. Все мои сцены были изменены правильно, мне просто пришлось внести несколько изменений в некоторые позиции, так как они были фиксированными координатами, а не относительными.
В настоящее время нет возможности легко загружать разные изображения, я подозреваю, что в ближайшие несколько дней будет принято новое соглашение об именах, аналогичное -hd.
Что касается вашего вопроса редактирования, вы, вероятно, обнаружите, что после включения 4-дюймового режима у вашего макета уже будет большое черное пространство вверху. Конечно, вы можете положить туда, что вы хотите.
Вы можете обнаружить, если это высокий экран, используя
[[UIScreen mainScreen] bounds].size.height
iOS автоматически поместит тонкие черные полосы с обеих сторон приложения, чтобы оно оставалось в соответствии с тем, как приложения были изначально разработаны для предыдущих версий iPhone
Несколько источников сообщают об этом, это отсюда.
Пока нет ни устройств, ни iOS 6, мы даже не знаем, нужно ли или какие модификации необходимо внести в cocos2d для поддержки iPhone 5. Перестаньте беспокоиться. Не думай Ждать и смотреть.
Как и во всех других устройствах, будут способы определения точного типа устройства. Опять же, это должно было бы подождать, пока мы не получим хотя бы iOS 6. Вы можете присоединиться к бета-программе в надежде узнать, но пока она находится в бета-версии, такая информация находится под NDA, и вы можете узнать ее, возможно, только через частную компанию Apple. форумы разработчиков.
COCOS2d - v2.x
замените CCFileUtils.h и.m следующими кодами и добавьте строку внутри делегата: [sharedFileUtils setiPhone5DisplaySuffix:@"-568h"]; // >>>>>> iPhone 5 -568h

Все вы предлагали хорошие решения, но для обозначения экрана ratina и изображений запуска iphone 5 будет какое-то соглашение об именах, например @ 2x и h @ 2x соответственно.
Спасибо Мано
