So can anybody suggest the folder where should i save this image so that the application works perfectly on device also.

Answer 1

You want to save it your applications Documents or Library folder. See the Files and Networking Programming Guide and specifically something like:

"Listing 6-1 Getting a file-system path to the application's Documents/ directory:"

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

Answer 2

看看此代码段http://snipplr.com/view/28080/save-image-example/ ，每个应用程序都有一个“文档”文件夹，您也可以在其中保存图像。

Answer 3

You would save it to the applications document or library folder. If you want the user to have access to it on the iPad, put it in the documents folder. If only code will access it, put it in the library folder.
