I have developed a sample iPad application in which I open the one file of type ppt in UIWebView. When I run this application on iPad having O.S version 5.0(iPad2) & 4.3.1(iPad1) the application gets crash with following error(Memory Warning):

But when I run same application on iPad having O.S version 4.3.3(iPad2) it runs perfectly. What is the reason behind this strange behavior & any solution to solve this. Thanks in advance.

your app is crashing because it ran out of memory. Try using PDF format or PPS (power point slide show) format. That may take some lesser space.

Ya I know its memory problem. But But same file gets open in the application which is present in the App store, which is specially designed for opening the ppt files. It works perfectly in that. – Samyag Shah Apr 11 '12 at 9:12
when a PDF file is loaded, whole file is not loaded into memory, only required pages are loaded. May be they are handling the PPTs in same way to reduce memory foot print. As you said its a dedicated app, may be they are processing the file manually instead of loading it into webview. – Tejesh Alimilli Apr 12 '12 at 7:47
