将.cpp改为.mm

修改代码

#if __APPLE__
#include <unistd.h>
#include <mach-o/dyld.h>
#include <Cocoa/Cocoa.h>
#endif

void init_ui()
{
 #if !__APPLE__
	setWindowFlag(Qt::FramelessWindowHint);
#else
	NSView* view = (NSView*)this->winId();
	NSWindow* wndd = [view window];
	wndd.titlebarAppearsTransparent = YES;
	wndd.titleVisibility = NSWindowTitleHidden;
	wndd.styleMask |= NSFullSizeContentViewWindowMask;
	[[wndd standardWindowButton : NSWindowZoomButton] setHidden:YES];
	[[wndd standardWindowButton : NSWindowMiniaturizeButton] setHidden:YES];
	[[wndd standardWindowButton : NSWindowCloseButton] setHidden:YES];
#endif // !__APPLE__
