Save image to camera roll with UIImageWriteToSavedPhotosAlbum

Question

I am trying to save a photo with a button to camera roll after user capture a picture with Camera , but I don\'t know why my picture doesn\'t save at photo library !!

Answer 1

First make sure you are calling savePhoto. Then you can add an assertion to check that the image is not nil:

- (IBAction) savePhoto {
    NSParameterAssert(img.image);
    UIImageWriteToSavedPhotosAlbum(img.image, nil, nil, nil);
}
