xcode8 运行项目时自己打印些东西

使用 Xcode 8 运行工程的时候,在打印台会发现如下这些奇怪的日志输出:

2016-09-19 10:43:47.128826 Demo[7100:171568] subsystem: com.apple.UIKit, category: Gesture, enable_level: 0, persist_level: 0, default_ttl: 1, info_ttl: 0, debug_ttl: 0, generate_symptoms: 0, enable_oversize: 1, privacy_setting: 2, enable_private_data: 0 

 

解决方法:
Xcode8里边 Edit Scheme... -> Run -> Arguments, 在Environment Variables里边添加 OS_ACTIVITY_MODE = disable
