The provided code doesn't have any code base related to the FTP server.
didFinishPickingMediaWithInfo delegate will trigger when you use/done a video selection from your picker controller. If you want to uploads the video to FTP at the same time without any button action, just use the below code.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSURL *mediaURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSData *videoData = [NSData dataWithContentsOfURL:videoURL];
//search for FTP code samples and upload this NSData to the FTP.
//save this video
NSString *moviePath = [mediaURL path];
if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum (moviePath)) {
UISaveVideoAtPathToSavedPhotosAlbum (moviePath, nil, nil, nil);
}
}
If you want an other action on the button which sends the video to the ftp server, save the Asset URL and retrieve the video files using ALAsset Url, convert this to strems and upload to FTP.
