ios保存录制好的视频到相簿的方法

注：使用 UIImageWriteToSavedPhotosAlbum 保存图像, UISaveVideoAtPathToSavedPhotosAlbum 保存视频. 4.0后使用 writeImageToSavedPhotosAlbum:metadata:completionBlock: 保存元数据.

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {       

    NSString* path = [[info objectForKey:UIImagePickerControllerMediaURL] path];

    // 保存视频

    UISaveVideoAtPathToSavedPhotosAlbum(path, self, @selector(video:didFinishSavingWithError:contextInfo:), nil);

    [self dismissModalViewControllerAnimated:YES];

 }

 

// 视频保存回调

- (void)video:(NSString *)videoPath didFinishSavingWithError:(NSError *)error contextInfo: (void *)contextInfo {

    NSLog(@"%@",videoPath);    

    NSLog(@"%@",error);

}
