CGDisplayIOServicePort在OS X> = 10.9中已弃用，该如何替换?

本文介绍了CGDisplayIOServicePort在OS X> = 10.9中已弃用，该如何替换?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我做了一个小型应用程序，以便快速更改多台显示器的屏幕分辨率.我想将产品名称显示为监视器的标题，使用此代码可以很容易地找到它:

I did small app to allow quickly change screen resolutions on multiple monitors. I want to show product name as title of the monitor, and it's very simple to find using this code:

NSDictionary *deviceInfo = (__bridge NSDictionary *)IODisplayCreateInfoDictionary(CGDisplayIOServicePort(dispID), kIODisplayOnlyPreferredName);

NSDictionary *localizedNames = [deviceInfo objectForKey:[NSString stringWithUTF8String:kDisplayProductName]];

if([localizedNames count] > 0) {
    _title = [localizedNames objectForKey:[[localizedNames allKeys] objectAtIndex:0]];
} else {
    _title = @"Unknown display";
}

但是在OS X> = 10.9中不推荐使用 CGDisplayIOServicePort ，Apple的文档说没有替代品.不使用此方法如何查找服务端口或产品名称?

But CGDisplayIOServicePort is deprecated in OS X >= 10.9 and Apple's documentation says there is no replacement. How to find service port or product name without using this method?

我尝试遍历IO注册表，并尝试使用 IOServiceGetMatchingServices 方法来查找显示服务，但是我对IO注册表不是很熟悉，因此找不到解决方案.

I tried to iterate through IO-registry and tried to use IOServiceGetMatchingServices method to find display services but I'm not very familiar with IO-registry so I couldn't find solution.

感谢帮助！
