AVFile 调用save的时候提示没有删除文件权限。

App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file.

Thread 6, name = (null) | +[AVErrorUtils errorFromJSON:] [Line 197] error: Error Domain=AVOS Cloud Error Domain Code=1 "Forbidden to delete by class permissions." UserInfo={error=Forbidden to delete by class permissions., NSLocalizedDescription=Forbidden to delete by class permissions., code=1}

可以将 save 时的 CURL 粘贴出来。

你可以打开网络请求日志。查看 curl 日志的方法如下:
首先,在 AVOSCloud 初始化语句的后面加上 [AVOSCloud setAllLogsEnabled:YES];
然后,重新编译运行应用,控制台就能看到每个请求的 curl 日志了。
