• 修改相册页面导航的背景颜色以及字体的颜色

- (void)navigationController:(UINavigationController *)navigationController   willShowViewController:(UIViewController *)viewController  animated:(BOOL)animated{  
 if ([navigationController isKindOfClass:[UIImagePickerController class]]){ viewController.navigationController.navigationBar.translucent = NO;
        viewController.edgesForExtendedLayout = UIRectEdgeNone;
        viewController.navigationController.navigationBar.barTintColor = UIColorFromHex(0x13c2fb);
        //title颜色和字体
        viewController.navigationController.navigationBar.titleTextAttributes = @{NSForegroundColorAttributeName:UIColorFromHex(0xffffff),
                                                   NSFontAttributeName:[UIFont systemFontOfSize:18]};
    }
}

如果要把字体改成中文只需在plist中把Localization native development region 的en状态换成chinese即可
