测试环境：ipad2 系统版本：6.1 其中当页面滑动的时候，未显示的图片我已经设为nil了，view我也remove掉了，但是滚动到20也左右就出现闪退了，求帮忙分析分析，采用ARC开发的。 1. 在Organizer中的Console文件最后提示如下（在标准输出里面未输出）： Dec 5 10:31:38 Administratorteki-iPad UserEventAgent[24]: jetsam: kernel termination snapshot being created Dec 5 10:31:38 Administratorteki-iPad com.apple.launchd[1] (com.apple.mobile.assertion_agent[9576]) : (com.apple.mobile.assertion_agent) Idle-exit job was jettisoned.

不是的，我就遇到和你一样的问题，是因为图片太多，堆积在内存中没释放到时内存不足系统直接杀掉程序。我已经做了一个可以支持大量大尺寸图片显示的scrollview。需要的话可以联系我。

其实实现的远离也很简单，做一个缓冲区，比方说你当前界面需要同时展示1张大图，那么你的缓冲区就可以缓冲3张（前一张，正在显示的一张，和后一张），这样子你始终在内存中只有三张，当滚动时，根据滚动的方向，卸掉一张，加载一张即可。
