我们也看到了这一点，目前，我们已经确保已配置打开上一个活动".

We're seeing that too, for the moment we've made sure 'opens last activity' is configured.

当用户界面处于活动状态时，我们启动dispatch_timer，以每隔1秒的间隔请求和处理数据.

When the UI is active we start a dispatch_timer to request and process data in 1 second intervals.

但是请确保使用NSUserProcessInfo方法进行任何重要的处理，并在不再活动时暂停一下dispatch_timers.否则，您将崩溃.

Make sure you do any significant processing using the NSUserProcessInfo method though and pause the dispatch_timers whenever you are no longer active. You'll get crashes otherwise.
