我正在尝试将我的视频文件从我的应用程序上传到服务器，我在uploadfilewitherror的代码中遇到异常。

提供的代码没有任何与FTP服务器相关的代码库。
当您从选择器控制器中使用/完成视频选择时， didFinishPickingMediaWithInfo委托将触发。如果您想在没有任何按钮操作的情况下同时将视频上传到FTP，请使用以下代码。
- (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);
}
}
如果您想在按钮上执行其他操作，将视频发送到ftp服务器，请保存资产URL并使用ALAsset Url检索视频文件，将其转换为strems并上传到FTP。
