更新：事实证明已经问过similar question，但我很难找到它，因为我的日志与其他问题的日志不同。虽然答案是相同的，但我认为我的问题对于其他人（比如我）很有帮助，他们在使用来自本机应用程序的日志消息搜索问题时很难找到解决方案。

Answer 1

我找到了解决方案：

关闭操作系统活动模式的详细信息

1. 从xcode菜单，Project - ＆gt;方案 - ＆gt;编辑方案。
2. 然后选择左侧的Run，然后选择右侧的Arguments标签。
3. 在Environment Variables中添加名称OS_ACTIVITY_MODE，将值添加为disable。

或者见下图。
