iphonesdk:Can'；图像数组中的t对角滚动？
我有一个大尺寸的图像。为了节省内存，我不想一次加载整个图片，所以我将图片分成9张图片，就像一个3X3数组iphonesdk:Can'；图像数组中的t对角滚动？,iphone,objective-c,uiscrollview,scroll,uiimageview,Iphone,Objective C,Uiscrollview,Scroll,Uiimageview,我有一个大尺寸的图像。为了节省内存，我不想一次加载整个图片，所以我将图片分成9张图片，就像一个3X3数组 036 147 258 我可以将较小的图像片段从一个图像滚动到相邻图像，如从（1,1）滚动到（1,2）（1,3），或从（1,1）滚动到（2,1）（3,1），但无法从（1,1）滚动到（2,2）或（3,3） 似乎我只能从一边到另一边或上下滚动图片，但不能对角滚动 如果我沿对角线滚动，则所有图像看起来都很混乱，如下所示： 360 471 582 如何在滚动时沿对角线滚动和/或跳过部分？ 这是我
