我的应用程序启动时出现 SIGABRT 错误。上面写着:
2011-07-19 14:01:51.321 App[364:707] -[AppViewController handle_VolumeChanged:]: unrecognized selector sent to instance 0x25d400
2011-07-19 14:01:51.386 App[364:707] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[AppViewController handle_VolumeChanged:]: unrecognized selector sent to instance 0x25d400'
我不知道它为什么会崩溃。我的代码中没有handle_VolumeChanged
任何地方。因为我的应用程序,我不想拥有它。是必需的吗?
