我已经添加了这些框架（AVFoundation、QuartzCore、CoreMotion、SystemConfiguration、Security、Social、CoreLocation、GLKit、MapKit）。
对于此类错误，您添加了以下框架：
资产库
地址簿
核心媒体
帐号
媒体播放器
您必须添加以下框架：
- CoreMotion.framework
- CoreMedia.framework
- Accounts.framework
- AssetsLibrary.framework
- AddressBook.framework
- MediaPlayer.framework
希望对您有所帮助。
