我的应用程序有某种僵尸问题。（不是 NSZombie 问题。就像是死而复生的问题。）
我首先注意到，在调试会话之后，当我去跑步时，我的 iPhone 上的音乐会每 7 分钟暂停一次，当我解锁设备时，应用程序名称会在状态栏中闪烁红色，就好像它刚刚坠毁。有时应用程序甚至会发出幻音，就像它仍在后台运行一样。
手动退出应用程序，继续。即使该应用程序不再出现在我正在运行的应用程序列表中，仍然会出现间歇性音频伪影。
当我重新插入时，每次应用程序僵尸化并重新启动时，它都会出现在控制台中。它看起来就像应用程序的正常启动！什么？什么可能触发我的应用程序自行重启？
安慰：

解决方案说明：结果很简单 - 1. 我正在关闭我的音频会话，dealloc但没有在applicationDidEnterBackground. 而且由于我使用kaudiosessioncategory_playandrecord它似乎告诉iOS如果它在后台崩溃时重新启动应用程序。
现在，为什么它在后台崩溃？……嗯，这是我的下一个任务。
