Multiple Cef Instance in mac

[rahulchavan10]

I want to run browser on click. Below mentioned "runBrowser" function is called on each click. But once any one browser is closed that cause CEF ShutDown and next time if I click on button ""runBrowser" function throws exception. I am working with CEF3 latest version on mac. Please help. Attahed Log for the same.
Any input will be greatly appreciated.



bool initialize = false;

CefRefPtr<CefClient> client = NULL;
CefRefPtr<ClientApp> app = NULL;

void runBrowser(){
if(! initialize){
CefMainArgs main_args;

// [ClientApplication sharedApplication];

app = new ClientApp(new ScriptingPbj());


int exit_code = CefExecuteProcess( main_args, app.get(), NULL );
if ( exit_code >= 0 ) {
exit(exit_code);
}

char cwd[1024];
getcwd( cwd, sizeof(cwd) );

CefSettings settings;

CefInitialize( main_args, settings, app.get(), NULL );

client = new ClientHandler();
}
initialize = true;
CefWindowInfo info;
CefBrowserSettings b_settings;

std::string path;
path = "https://www.google.com";



info.SetAsChild(NULL, 0, 0, 512, 270);
CefBrowserHost::CreateBrowser(info, client.get(), path, b_settings, NULL);

CefRunMessageLoop();
CefShutdown();
}


@implementation HandleEvents


- (IBAction)runBrowser:(id)sender
{
runBrowser();
}

@end

Look at what your ClientHandler does in the OnBeforeClose callback.

It only sets browser to NULL, nothing else is there.
Are you expecting some more things to be done there?

On each click you execute "runBrowser" function and that function is calling CefShutdown each time along with message loop. Message loop and shutdown should be called only once during app lifetime.
