ScreneDelegate 下 customWindow 会无效

[huanglins]

- (UIWindow *)customWindow {
    if (!_customWindow) {
        if (@available(iOS 13.0, *)) {
            UIWindowScene *windowScene = nil;
            for (UIScene *scene in [UIApplication sharedApplication].connectedScenes) {
                if(scene.activationState == UISceneActivationStateForegroundActive) {
                    windowScene = (UIWindowScene *)scene;
                }
                if(!windowScene && [UIApplication sharedApplication].connectedScenes.count == 1) { 
                    windowScene = (UIWindowScene *)scene;
                }
            }
            if (windowScene) {
                _customWindow = [[UIWindow alloc] initWithWindowScene:windowScene];
            }
        } else {
            _customWindow = [[UIWindow alloc] initWithFrame:CGRectZero];
        }
    }
    return _customWindow;
}

这样可以进行兼容
