【中文标题】MyApp“有超出允许时间的活动断言”崩溃 - CoreLocationRegistration 和 CoreLocationBackgroundClient【英文标题】：MyApp "has active assertions beyond permitted time" crash - CoreLocationRegistration and CoreLocationBackgroundClient 【发布时间】：2011-07-08 04:16:20 【问题描述】：

有人知道为什么会发生此崩溃日志吗？该应用程序记录了用户去的位置。所以它在 Info.plist 中设置了 UIBackgroundModes 的 Location 以继续在后台获取位置更新。根据日志，10 分钟后似乎发生了崩溃。
