Save In-App Video To Camera Roll?

camera, iphone, video

Solution

You could try this code assuming you already know how to save an image:

-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
    if([mediaType isEqualToString:(NSString *)kUTTypeMovie]) {
       //Save the video
       NSURL *movieUrl = [info objectForKey:UIImagePickerControllerMediaURL];
       UISaveVideoAtPathToSavedPhotosAlbum([movieUrl relativePath], self,@selector(movie:didFinishSavingWithError:contextInfo:), nil);
    }
}

Or you could try:

-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
  if([mediaType isEqualToString:(NSString *)kUTTypeMovie]) {
    NSURL *movieUrl = [info objectForKey:UIImagePickerControllerMediaURL];
    ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
    [library writeVideoAtPathToSavedPhotosAlbum:movieUrl completionBlock:^(NSURL *assetURL, NSError *error){
        if(error) {
            NSLog(@"CameraViewController: Error on saving movie : %@ {imagePickerController}", error);
        }
        else {
            NSLog(@"URL: %@", assetURL);
        }
    }];
  }
}

Problem

Is it possible to take a video that is embedded within the app and save it to the camera roll? If so, how? Is it the same UIWriteImage thing?
