在后台运行应用程序时未触发OS X Cocoa计时器 [英] OS X Cocoa timer not fired when application on background

问题描述

第三方库提供了我需要每100毫秒调用一次的功能.只要我的应用程序处于前台状态，设置一个计时器就可以很好地工作.当我的应用程序在后台运行时，计时器会工作一会儿，但是大约一分钟后，只有在延迟10秒后才调用计时器.当我使用usleep-function创建一个单独的线程时，也会发生同样的情况.有什么方法可以让我的应用程序在后台运行时保持计时器运行?

A third-party library provides a function I need to call every 100ms. Setting up a timer to do that works very well as long as my app is on foreground. When my app is on background timer works for a while but after a about a minute timer is called only after 10 second delay. The same happened when I created a separate thread with usleep-function. Is there any way I can keep timer running while my app is on background?
