How to save picture to iPhone photo library?
camera, cocoa-touch, ios, iphone, uiimage
Solution
You can use this function:
UIImageWriteToSavedPhotosAlbum(UIImage *image,
id completionTarget,
SEL completionSelector,
void *contextInfo);
You only need completionTarget, completionSelector and contextInfo if you want to be notified when the `UIImage` is done saving, otherwise you can pass in `nil`.
See the official documentation for `UIImageWriteToSavedPhotosAlbum()`.
Problem
What do I need to do to save an image my program has generated (possibly from the camera, possibly not) to the system photo library on the iPhone?
