在MacOS 10.9(Mavericks)应用程序中禁用App Nap [英] Disable App Nap in MacOS 10.9 (Mavericks) application

问题描述

我正在编写一个接收OSC消息的应用程序.但是，由于10.9的App-Nap技术，应用程序在离开前台后停止对这些消息作出反应. 我想为在10.9上运行的应用程序禁用AppNap，但仍然能够在10.8上运行，因此我尝试了这段代码，但未显示任何效果.

I am writing an application that receives OSC messages. However, due to 10.9's App-Nap-technology the application stops reacting on these messages after leaving foreground. I want to disable AppNap for my application running on 10.9, but still be able to run on 10.8, so I tried this piece of code, but it does not show any effect.

if ([[NSProcessInfo processInfo] respondsToSelector:@selector(beginActivityWithOptions:reason:)]) {
    [[NSProcessInfo processInfo] beginActivityWithOptions:0x00FFFFFF reason:@"receiving OSC messages"];
}

在 github 上查看完整代码.

if条件似乎按预期工作，并在10.9台计算机上执行.但是，尽管如此，该应用仍被发送到睡眠状态. (活动监视器在我的应用程序中显示"App Nap:Yes").

The if-condition seems to work as expected and is executed on 10.9-machines. But nevertheless the app is sent to sleep. (Activity Monitor shows "App Nap: Yes" for my application).

感谢您的帮助！

推荐答案

活动需要存储在属性中.所以我将其添加到了头文件中:

the activity need to be stored in a property. So I added this in the header-file:

@property (strong) id activity;

然后使用此实现.

if ([[NSProcessInfo processInfo] respondsToSelector:@selector(beginActivityWithOptions:reason:)]) {
    self.activity = [[NSProcessInfo processInfo] beginActivityWithOptions:0x00FFFFFF reason:@"receiving OSC messages"];
}
