设置NavigationBar为全透明的时候，statusBarStyle无法设定为Light

问题： 设置NavigationBar为全透明的时候，statusBarStyle无法设定为Light
描述:

当我push到将当前视图控制器的navigationBar设定为全透明时,

- (void)viewDidLoad {
    [super viewDidLoad];
//     Do any additional setup after loading the view from its nib.
    //设定字体颜色
    self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
    //设定背景图片为空
    [self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
    //半透明
    //self.navigationController.navigationBar.translucent = YES;
    //
    //self.edgesForExtendedLayout = UIRectEdgeNone;
}

- (UIStatusBarStyle)preferredStatusBarStyle {
    return UIStatusBarStyleLightContent;
}

然而顶部的状态栏是漆黑一片。
我的上一级VC也使用了preferredStatusBarStyle，但是显示没有问题，不同在于上一级VC隐藏了NavigationBar，而push到当前VC的时候是显示NavigationBar的..
求解各位大神！

解决方案1:

终于在stackoverflow找到对应的解答，加上下面这句
self.navigationController.navigationBar.barStyle = UIBarStyleBlack;

I discovered that if your ViewController is inside a
navigationController then the navigationController’s
navigationBar.barStyle determines the statusBarStyle.

Setting your navigationBar’s barStyle to UIBarStyleBlackTranslucent
will give white status bar text (ie. UIStatusBarStyleLightContent),
and UIBarStyleDefault will give black status bar text (ie.
UIStatusBarStyleDefault).

Note that this applies even if you totally change the navigationBar’s
color via its barTintColor.
