前言
之前尝试过用原生的上传代码，但是比较麻烦，利用afnetworking进行上传还是很方便的。
文件上传后台服务器必须要有相应的代码支持，我们后台使用java做的，首先ios客户端要把上传的图片或者视频转换成标准的文件流，然后传给后台，才能顺利实现上传功能。

图片多选
如果想要一次上传多张图片的话，可能会用到
AssetsPickerController
这个第三方库
我在代码中用法如下:
-(void)takeVedios:(UIButton *)btn{
[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status){
dispatch_async(dispatch_get_main_queue(), ^{
// init picker
CTAssetsPickerController *picker = [[CTAssetsPickerController alloc] init];
// set delegate
picker.delegate = self;
// Optionally present picker as a form sheet on iPad
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
picker.modalPresentationStyle = UIModalPresentationFormSheet;
// present picker
[self presentViewController:picker animated:YES completion:nil];
});
}];
}
补充
上传的时候最好有进度条进行提示，这是比较好的用户体验，AFNetworking官方也给出了上传下载的进度条实例，我这块之前没有做出很好的效果，以后有时间了再研究一下。
我用的AF的版本号是2.6的可能和最新版本的AF上传的代码有点区别，进度条的展示可能也有点区别，AFNetworking中的进度条用了NSProcess来显示，NSProcess可以用 KVO来监控实现，

经过检验，进度条显示有点问题，可能不是实时显示，进度条显示的不太准确。需要后期优化。
