在“照片”应用中存储CGImage？（iPhone）

Question

可以说我有一个CGImage并想将其存储在每台iPod Touch / iPhone附带的Photos应用程序中，我该怎么做？

Answer 1

First convert the CGImage to a UIImage :

UIImage *_myImage = [UIImage imageWithCGImage:cgImage];

And then use the UIImageWriteToSavedPhotosAlbum() function:

UIImageWriteToSavedPhotosAlbum(UIImage *image, id completionTarget, SEL completionSelector, void *contextInfo);

to write the UIImage to the Photo Album.
