我的应用有某种僵尸问题。 (不是NSZombie问题。就像,一个从死里复出的问题。)
我首先注意到在调试会话之后,当我要去运行时,我的iPhone上的音乐会每隔约7分钟暂停一次,当我解锁设备时,应用程序名称将在状态栏中闪烁红色好像它刚刚崩溃了有时甚至会有来自应用程序的幻影声音,就像它仍在某种程度上在后台运行一样。
手动退出应用,继续。即使应用程序不再出现在我正在运行的应用程序列表中,仍会获得间歇性的音频工件。
当我重新插入时,每次应用程序僵尸化并重新启动时,这都在控制台中。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重新启动?

解决方案说明:结果很简单 - 1.我在dealloc
关闭了我的音频会话,但没有关注applicationDidEnterBackground
。因为我正在使用kaudiosessioncategory_playandrecord
,如果它在后台崩溃,似乎会告诉iOS重启应用程序。
现在,为什么它会在后台崩溃? ......好吧,这是我的下一个任务。

该应用可能设置了背景voip标志。如果是,则操作系统将在异常退出时(或设备重新启动时)重新启动应用程序。

我们可能还需要代码片段,因为日志不告诉我们执行了什么代码
