什么是UpdateSystemActivity的Cocoa等价物？ [英] What is the Cocoa equivalent of UpdateSystemActivity?

问题描述

我将Carbon应用程式转换为Cocoa应用程式，但找不到Cocoa等效项：

I'm converting a Carbon app to a Cocoa app and I can't find the Cocoa equivalent for:

UpdateSystemActivity(UsrActivity);

任何Mac人都在指望我朝正确的方向？感谢。

Any Mac people out there care to point me in the right direction? Thanks.

UPDATE ：我正在建设64位。建立32bit工作正常，但我得到的符号未声明在此范围错误UpdateSystemActivity（和其他人）时，我建立64位。

UPDATE: I'm building 64bit. Building 32bit works fine, but I get symbol not declared in this scope errors for UpdateSystemActivity (and others) when I build for 64bit.

UPDATE2 ：我要导入以下内容：

UPDATE2: I'm importing the following:

#import <Cocoa/Cocoa.h>
#import <Carbon/Carbon.h>
#import <OpenGL/CGLMacro.h>

在构建64位时需要导入其他东西吗？

Is there some other thing I need to import when building 64bit?

UPDATE3 ：添加 #import< CoreServices / CoreServices.h> 没有帮助。我仍然得到编译器错误，告诉我UpdateSystemActivity和UsrActivity没有在这个范围内声明。

UPDATE3: Adding #import <CoreServices/CoreServices.h> did not help. I still get compiler errors telling me UpdateSystemActivity and UsrActivity was not declared in this scope.

UPDATE4 ：好的，文件在OSServices / 。H。我正在构建针对10.5 SDK，并快速搜索显示：

UPDATE4: Okay, file not found on OSServices/Power.h. I'm building against the 10.5 SDK and a quick search shows:

$ pwd
/Developer/SDKs
$ find . -name Power.h
./MacOSX10.3.9.sdk/Developer/Headers/CFMCarbon/OSServices/Power.h
./MacOSX10.3.9.sdk/Developer/Headers/CFMCarbon/Power.h
./MacOSX10.3.9.sdk/Developer/Headers/FlatCarbon/Power.h
./MacOSX10.3.9.sdk/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/OSServices.framework/Versions/A/Headers/Power.h

./MacOSX10.4u.sdk/Developer/Headers/CFMCarbon/OSServices/Power.h
./MacOSX10.4u.sdk/Developer/Headers/CFMCarbon/Power.h
./MacOSX10.4u.sdk/Developer/Headers/FlatCarbon/Power.h
./MacOSX10.4u.sdk/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/OSServices.framework/Versions/A/Headers/Power.h

./MacOSX10.5.sdk/Developer/Headers/FlatCarbon/Power.h
./MacOSX10.5.sdk/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/OSServices.framework/Versions/A/Headers/Power.h

但我得到：

Mac.mm:6:29: error: OSServices/Power.h: No such file or directory
Mac.mm:6:29: error: OSServices/Power.h: No such file or directory

推荐答案

您仍然可以调用 UpdateSystemActivity

API的文档指定导入 CoreServices / CoreServices.h 获取API - 但是通过标题（特别是在 OSServices / OSServices.h 中）搜索显示在64位环境中省略了该文件。然而，有一些 Power.h （其中 UpdateSystemActivity 被定义）被关闭64位， code> UpdateSystemActivity 不是其中之一。

The documentation for the API specifies importing CoreServices/CoreServices.h to get the API -- however hunting through the headers (notably in OSServices/OSServices.h) shows that the file is omitted in a 64bit environment. Nevertheless, there are sections of Power.h (where UpdateSystemActivity is defined) that are turned off for 64bits, and UpdateSystemActivity is not one of them.

鉴于此，请尝试 #import< ; OSServices / Power.h> ，看看是否能正常工作。 （您必须在项目中包含CoreServices框架，以便找到标题。）

In light of that, try to #import <OSServices/Power.h> directly and see if that works. (You'll have to include the CoreServices framework in your project for the header to be found as well.)
