如何更改默认导航项颜色

Question

我有一个导航栏，我想将其左侧项目的默认颜色更改为白色。

我想让蓝色变成白色

我想以编程方式完成此操作。目前我正在使用此代码更改导航栏的颜色和标题

- (void)viewWillAppear:(BOOL)animated
 {
  [self.navigationController setNavigationBarHidden:NO];
self.navigationItem.title = @"Advanced Settings";
UIColor *bg = [UIColor colorWithRed:79/255.0f green:166/255.0f blue:196/255.0f alpha:1.0f];

if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) {
    // iOS 6.1 or earlier
    self.navigationController.navigationBar.tintColor = bg;
   self.navigationController.navigationBar.titleTextAttributes = @{NSForegroundColorAttributeName: [UIColor whiteColor]};

} else {
    // iOS 7.0 or later
    self.navigationController.navigationBar.barTintColor = bg;
    self.navigationController.navigationBar.translucent = NO;
    self.navigationController.navigationBar.titleTextAttributes = @{NSForegroundColorAttributeName: [UIColor whiteColor]};
}
 }
