Set Image Name in iOS Camera Roll

Save-iOS-image-name.md

Although the file name for the image is set automatically by iOS to IMG_nnnn, we can use metadata to set the title that will be shown in Photos app.

ViewController.m

- (void) imagePickerController: (UIImagePickerController *)picker didFinishPickingMediaWithInfo: (NSDictionary *)info
{
    [self dismissViewControllerAnimated:YES completion:nil];
    UIImage *image = info[UIImagePickerControllerOriginalImage];
    NSMutableDictionary *metadata = info[UIImagePickerControllerMediaMetadata];
 
    // set image name and keywords in IPTC metadata
    NSString *iptcKey = (NSString *)kCGImagePropertyIPTCDictionary;
    NSMutableDictionary *iptcMetadata = metadata[iptcKey];
    iptcMetadata[(NSString *)kCGImagePropertyIPTCObjectName] = @"Image Title";
    iptcMetadata[(NSString *)kCGImagePropertyIPTCKeywords] = @"some keywords";
    metadata[iptcKey] = iptcMetadata;
 
    // set image description in TIFF metadata
    NSString *tiffKey = (NSString *)kCGImagePropertyTIFFDictionary;
    NSMutableDictionary *tiffMetadata = metadata[tiffKey];
    tiffMetadata[(NSString *)kCGImagePropertyTIFFImageDescription] = @"Description for image"; // only visible in iPhoto when IPTCObjectName is set
    metadata[tiffKey] = tiffMetadata;
 
    // save image to camera roll
    ALAssetsLibrary library = [[ALAssetsLibrary alloc] init];
    [library writeImageToSavedPhotosAlbum:image.CGImage metadata:metadata completionBlock:nil];
}
