CABasicAnimation, вращение, значительное замедление

Question

Я создал анимированное цветовое колесо, в котором пользователь перемещается по различным видам и каждый раз, когда колесо поворачивается к следующему цвету. Каждый вид загружается кнопками навигации, звуковыми кнопками, картинками и т. Д.

Все работает отлично, за исключением того, что каждый раз, когда вызывается анимация, изображение остается на заднем плане и в конечном итоге приводит к значительному замедлению анимации.

Анимация длится около 1,8 секунд каждый раз, а используемое изображение имеет размер 800x800, при этом в любое время отображается около 320x400.

Из того, что я могу понять, после того, как анимация закончена, она не выпускается. Я пытался удалить removeFromSuperview, но это означает, что в следующий раз, когда я перейду к следующему представлению, оно исчезнет.

Вот код, у меня 8 экранов, на каждом из которых есть кнопки «Назад» и «Далее» для навигации. Первый вид отображает полностью вращающееся цветовое колесо, которое отлично работает, и кнопку запуска.

Это весь мой .m, и мне жаль, если много повторяющегося кода, но я оставил его, чтобы дать лучшее представление о том, что я делаю.

Все это происходит, когда пользователь выбирает один из четырех вариантов на начальном экране.

Спасибо.

Answer 1

Ваше выделение imgView в каждом методе, не выпуская его снова, это создаст утечку. Вы можете сделать:

UIImageView *imgView =[[[UIImageView alloc] initWithImage:image] autorelease];

или отпустите его как

[self addSubview:imgView];
[imgView release];

Вы можете проверить наличие утечек, перейдя к Build -> Build and Analyse в строке меню
