1、升级Xcode8之后，原项目运行时在控制台多出了一些日志信息，如下所示：
1 2 3 4 5 | 2016-09-18 15:38:17.290635 Test[1243:287383] subsystem: com.apple.UIKit, category: HIDEventFiltered, enable_level: 0, persist_level: 0, default_ttl: 0, info_ttl: 0, debug_ttl: 0, generate_symptoms: 0, enable_oversize: 1, privacy_setting: 2, enable_private_data: 0 2016-09-18 15:38:17.293846 Test[1243:287383] subsystem: com.apple.UIKit, category: HIDEventIncoming, enable_level: 0, persist_level: 0, default_ttl: 0, info_ttl: 0, debug_ttl: 0, generate_symptoms: 0, enable_oversize: 1, privacy_setting: 2, enable_private_data: 0 2016-09-18 15:38:17.304381 Test[1243:287378] subsystem: com.apple.BaseBoard, category: MachPort, enable_level: 1, persist_level: 0, default_ttl: 0, info_ttl: 0, debug_ttl: 0, generate_symptoms: 0, enable_oversize: 0, privacy_setting: 0, enable_private_data: 0 2016-09-18 15:38:17.324387 Test[1243:287071] subsystem: com.apple.UIKit, category: StatusBar, enable_level: 0, persist_level: 0, default_ttl: 0, info_ttl: 0, debug_ttl: 0, generate_symptoms: 0, enable_oversize: 1, privacy_setting: 2, enable_private_data: 0 2016-09-18 15:38:17.495029 Test[1243:287071] subsystem: com.apple.BackBoardServices.fence, category: App, enable_level: 1, persist_level: 0, default_ttl: 0, info_ttl: 0, debug_ttl: 0, generate_symptoms: 0, enable_oversize: 0, privacy_setting: 0, enable_private_data: 0 |
2、在网上找了一些资料，目前还没细研究是怎么回事，但有办法取消日志输出，具体操作是Product–>Scheme–>Edit Scheme…
3、在Run的Enviroment Variables中添加Name为OS_ACTIVITY_MODE的键，值为Disable，前面要记得勾选哦。如下图所示
