아이폰 SDK : 이미지 배열에서 대각선 스크롤링이 불가능합니까?

Question

큰 이미지가 있습니다. 나는 한 번에 전체 그림을로드하지 않도록 메모리를 저장, 그래서는 3X3 배열처럼 (9 개) 사진에 이미지를 분할하려면

가 나는 하나 개의 이미지에서 작은 이미지 조각을 스크롤 할 수 있습니다 (1,1) ~ (1,2) (1,3) 또는 (1,1) ~ (2,1) (3,1)과 같이 인접한 이미지를 스크롤 할 수는 없습니다. 1,1) ~ (2,2) 또는 (3,3).

사진을 좌우로 또는 위아래로 스크롤 할 수 있지만 대각선으로는 스크롤 할 수없는 것처럼 보입니다. 내가 대각선 스크롤하면

, 모든 이미지는이처럼 엉망이 보인다 :

어떻게 대각선 스크롤 및/또는 스크롤하는 동안 섹션을 건너 뛸 수 있습니다?

UIScrollView를 살펴 보았습니까?

특히, 더 큰 이미지를 타일로 다지기위한 방법을 보여주는 샘플 코드 (ImageSuite, 나는 믿습니다)가 있으며, 원하는 방향으로 만 원하는 방향으로 스크롤 할 수 있습니다.

이것은 MKMapView (Maps.app)가 작동하는 방식과 매우 흡사합니다.
