dyld：找不到符号：_MPMoviePlayerPlaybackStateDidChangeNotification
我正在构建使用 MPMoviePlayerViewController 来播放视频的通用应用程序。观察通知“MPMoviePlayerPlaybackStateDidChangeNotification”。该应用程序在 iPad 模拟器中成功运行，但在 iPhone 中运行时抛出以下错误：-
dyld：未找到符号：_MPMoviePlayerPlaybackStateDidChangeNotification 引用自：/Users/veer/Library/Application Support/iPhone Simulator/3.0/Applications/27BC67AA-72D1-4DD2-9146-0126FCC8E90C/test.app/eReader 预计位于：/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/MediaPlayer.framework/MediaPlayer 在 /Users/veer/Library/Application Support/iPhone Simulator/3.0/Applications/27BC67AA-72D1-4DD2-9146-0126FCC8E90C/test.app/eReader 中
有人遇到同样的问题并得到解决吗？
提前致谢！
