Custom UIwindow not display

Question

I'm trying to create a new window for Custom alert on rootViewController.

- (void)viewdidAppear
{
            UIWindow *newWindow = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
            newWindow.windowLevel = UIWindowLevelAlert + 1.0f;
            newWindow.backgroundColor = [UIColor redColor];
            newWindow.hidden = NO;

        UIViewController *vc = [[UIViewController alloc] init];
        vc.view.backgroundColor = [UIColor blueColor];
        newWindow.rootViewController = vc;

        [newWindow makeKeyAndVisible];

But the newWindow not working. I am confused with this strange question. I hope you can help me.

Where is that code, please? Show the context. Explain what you are trying to do. Thanks. — matt, Jan 18 '15 at 02:28

But the correct way to make a custom alert is to use a presented view controller. That is what you should be doing. — matt, Jan 18 '15 at 03:23
