我正在尝试在Mac应用程序上运行本机对象c代码。
我的代码如下:
MainWindow.h:
#ifdef Q_OS_MAC
#include <Carbon/Carbon.h>
#include <ctype.h>
#include <stdlib.h>
#include <stdio.h>
#include <mach/mach_port.h>
#include <mach/mach_interface.h>
#include <mach/mach_init.h>
#include <IOKit/pwr_mgt/IOPMLib.h>
#include <IOKit/IOMessage.h>
#endif

MainWindow.cpp:
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
#ifdef Q_OS_MAC
[[[NSWorkspace sharedWorkspace] notificationCenter] addObserver: self
selector: @selector(receiveSleepNote:)
name: NSWorkspaceWillSleepNotification object: NULL];
#endif
}
#ifdef Q_OS_MAC
- (void) receiveSleepNote: (NSNotification*) note
{
NSLog(@"receiveSleepNote: %@", [note name]);
}
#endif

但是正在收到似乎QT无法理解代码结构的错误:
application.cpp:错误:预期的外部声明-(void)receiveSleepNote:(NSNotification *)注意^
