我的应用需要访问设备上的日历数据库。对于 ios6，我在应用程序首次运行时请求许可，如果允许，一切正常。但是，如果应用程序在后台并且用户关闭应用程序的权限，我的代码会崩溃并跳转到主循环并在以下位置停止：

return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));

任何想法如何解决这个问题。

感谢

礼萨

进一步补充：

这是崩溃的堆栈跟踪

如果我在更改相应设置时处于调试过程中，我也会遇到同样的问题。

虽然我认为因为我们收到 SIGKILL(not SIGABRT) 这意味着这是预期的行为。

基本上操作系统中的某些内容发生了变化，并且所有依赖于更改的应用程序都应该重新启动。至少我是这么看的。
