How to save picture to iPhone photo library?
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()
.
Deprecated in iOS 9.0.
There`s much more fast then UIImageWriteToSavedPhotosAlbum way to do it using iOS 4.0+ AssetsLibrary framework
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init]; [library writeImageToSavedPhotosAlbum:[image CGImage] orientation:(ALAssetOrientation)[image imageOrientation] completionBlock:^(NSURL *assetURL, NSError *error){ if (error) { // TODO: error handling } else { // TODO: success handling }}];[library release];
The simplest way is:
UIImageWriteToSavedPhotosAlbum(myUIImage, nil, nil, nil);
For Swift
, you can refer to Saving to the iOS photo library using swift
