Objective-C在Qt与小牛 [英] Objective-C in Qt with Mavericks

问题描述

我一直在使用Objective-C混合C ++在Qt没有任何问题;在需要时使用.mm文件。

I've been using Objective-C mixed with C++ in Qt without any issues; using .mm files where required.

将构建机器升级到Mavericks后，我最初注意到框架头文件丢失，因此安装了XCode命令行工具问题。

After upgrading my build machine to Mavericks, I initially noticed that the framework headers were missing, so installed the XCode command line tools, which fixed the issue.

现在，我编译Objective-C文件时遇到错误，抱怨框架中的代码。例如：

Now, I'm getting a problem compiling Objective-C files with errors complaining about code in the frameworks. For example: -

系统/库/ Frameworks / Foundation.framework /版本/ C / Headers / NSUserNotification.h：16：44：错误：在枚举器之间缺少'，'
NSUserNotificationActivationTypeReplied NS_AVAILABLE（10_9，NA）= 3

System/Library/Frameworks/Foundation.framework/Versions/C/Headers/NSUserNotification.h:16:44: error: missing ',' between enumerators NSUserNotificationActivationTypeReplied NS_AVAILABLE(10_9, NA) = 3

b
$ b

And

/System/Library/Frameworks/AppKit.framework/Versions/C/Headers/NSApplication.h:58:34：错误：expected';'after top级别声明者
typedef NSInteger NSModalResponse NS_AVAILABLE_MAC（10_9）;

/System/Library/Frameworks/AppKit.framework/Versions/C/Headers/NSApplication.h:58:34: error: expected ';' after top level declarator typedef NSInteger NSModalResponse NS_AVAILABLE_MAC(10_9);

我升级到Qt 5.2.1，保留，它来自包括标准框架标题;在这种情况下： -

I've upgraded to Qt 5.2.1, but the issues remain and it's coming from including standard framework headers; in this case: -

#import <NSUserNotification.h>
#import <NSApplication.h>

有人可以解释一下Mavericks的变化，以及如何解决这些错误？

Can someone please explain what's changed in Mavericks and how I can fix these errors?

推荐答案

您应该包括框架作为Framework / Header.h 。

以下作品适用于我：

#project.pro
TEMPLATE = app

LIBS += -framework AppKit -framework Foundation

OBJECTIVE_SOURCES = main.mm

//main.mm
#import <Foundation/NSUserNotification.h>
#import <AppKit/NSApplication.h>
#include <QCoreApplication>

int main(int argc, char ** argv)
{
   QCoreApplication a(argc, argv);
   NSApplication * app = [NSApplication sharedApplication];
   return 0;
}
