什么是“用于发展”？ Xcode Organizer中的按钮是否适用于iOS设备？ [英] What does the "Use for Development" button in Xcode Organizer do to an iOS device?

问题描述

选择iOS设备并点击Xcode管理器中的用于开发按钮时，设备（iPhone或iPad）上有什么变化？

When selecting an iOS device and clicking the "Use for Development" button in Xcode organizer, what does it change on the device (iPhone or iPad)?

是是否安装了调试符号或某种分析器或记录器？

Are there any debugging symbols installed or some sort of profilers or loggers?

此模式在用于开发时会影响设备性能或电池寿命吗？

Does this mode affect device performance or battery life while being "used for development"?

推荐答案

根据我的经验，打开设备进行开发的实际后果是记录数据的级别和对这些日志的访问。 （我不确定是否为所有应用程序激活了日志，或者只是为自己开发的应用程序激活了日志。）

From my experience, the practical consequences of turning on a device for development are an increase of levels of logged data and access to these logs. (I'm not sure if logs are activated for all apps or just those you develop yourself.)

这种额外的日志记录活动可能会对存储产生影响并对能源产生影响当你测试你开发的应用程序时，你大部分时间都插在运行XCode的机器上，当我切换回我的设备的常规用户时，我从未看到对电池寿命的任何影响（相反，开发者用户）。

This extra logging activity might have a storage impact and an impact on energy consumed too but as you're most of the time plugged in a machine running XCode when you test the applications you develop, I never saw any impact on the battery life when I switched back to be a regular user of my device (as opposed to a developer user).
