i want to play a mp3 using a http url,so i found Qt5 MediaPlayer. But i get a issue,when i set player->setMedia(QUrl('http://xxx'));.
2016-01-02 01:46:02.544 myPlayer[82519:5587404] 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.
i found this, but i don't know how to add NSAllowsArbitraryLoads to info.plist.
