xocde 8.0 出來后，有很多的改變，需要一點(diǎn)一點(diǎn)的去探索與學(xué)習(xí)唇牧。
Xcode 8.0 未修改配置直接編譯會出現(xiàn)下面的警告：（我這人有點(diǎn)毛病，就是不喜歡警告打印出來）
運(yùn)行xcode8遇到這個(gè)警告：
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
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
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
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
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
去除這些警告的方法：
product -> scheme -> edict scheme -> run -> environment variables?
輸入：
name:OS_ACTIVITY_MODE ??
value:disable
最后：close
重新編譯就去除了這些警告了聚唐。
