- (void)viewDidLoad {
    [super viewDidLoad];

    self.navigationBar.barTintColor = [UIColor redColor];
    //返回按钮颜色
    UIImage *backButtonImage = [[UIImage imageNamed:@"navigator_btn_back"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 30, 0, 0)];
    [[UIBarButtonItem appearance] setBackButtonBackgroundImage:backButtonImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

//这句就是在PUSH出界面的时候去掉文字只显示一个返回按钮
[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(NSIntegerMin, NSIntegerMin) forBarMetrics:UIBarMetricsDefault];

//导航栏的文字属性

self.navigationBar.tintColor = [UIColor whiteColor];

self.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],NSForegroundColorAttributeName,[UIFont boldSystemFontOfSize:17.0],NSFontAttributeName ,nil];

}

//如果有标签栏每次推出的时候加上这个方法就会隐藏底部的标签栏

-(void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated{
    if (self.viewControllers.count) {
        viewController.hidesBottomBarWhenPushed = YES;
    }
    [super pushViewController:viewController animated:animated];
}
/**
* 导航控制器统一管理状态栏颜色
* @return 状态栏颜色
*/
-(UIStatusBarStyle)preferredStatusBarStyle{
    return UIStatusBarStyleLightContent;

}

- (void)configureAppearance {
    self.window.backgroundColor = [UIColor whiteColor];

    // 0x2F434F
    [UINavigationBar appearance].barTintColor = [UIColor colorWithRed:(48 - 40) / 215.0 green:(67 - 40) / 215.0 blue:(78 - 40) / 215.0 alpha:1];
    [UINavigationBar appearance].barStyle = UIBarStyleBlack;
    [UINavigationBar appearance].tintColor = [UIColor whiteColor];

    [UISegmentedControl appearance].tintColor = [UIColor whiteColor];

    [UITabBar appearance].tintColor = HexRGB(colorI3);
}
