Saving images from web

I am new to IOS development. I am developing an app in which i am viewing some images in my app that are stored on a server. The 开发者_JAVA技巧thing is that, i want an image from the server to store in my photo gallery. anyone know the procedure?

Thanks for every help;

You will have implement web services to access images from server, so that it can be downloaded to your iPhone App.

Look up the documentation for the UIImageWriteToSavedPhotosAlbum function. It will save a UIImage to the camera roll.
