Unable to set color of UIViewController navigation bar

Question

I'm presenting my view controller with the following code:

UINavigationController* navigation = [[UINavigationController alloc] initWithRootViewController:sessionController];
[self presentViewController:navigation animated:YES completion:^{

}];

from within the presented view controller "viewDidLoad" method I'm attempting to set the navigation bar color with the following, but I am not successful:

self.navigationController.navigationBar.tintColor = [UIColor blackColor];
self.navigationController.navigationBar.backgroundColor = [UIColor blackColor];
self.navigationController.view.backgroundColor = [UIColor blackColor];
UINavigationBar.appearance.backgroundColor = [UIColor blackColor];
UINavigationBar.appearance.tintColor = [UIColor blackColor];

The navigation bar color will NOT change from white. Any advice would be much appreciated.

Note: I am not using story boards or XIB files.

Answer 1

Try the following code to change the background color:

[self.navigationController.navigationBar setBarTintColor:[UIColor blackColor]];
[self.navigationController.navigationBar setTranslucent:NO];

Answer 2

The navigation controller object create when applied the color. Like this below example.

UINavigationController* navigation = [[UINavigationController alloc] initWithRootViewController:sessionController];

navigation.navigationBar.tintColor = [UIColor blackColor];
navigation.navigationBar.backgroundColor = [UIColor blackColor];
navigation.navigationBar.barTintColor = [UIColor blackColor];


[self presentViewController:navigation animated:YES completion:^{

}];

And below this method all navigation controller change color.

UINavigationBar.appearance.backgroundColor = [UIColor blackColor];
UINavigationBar.appearance.tintColor = [UIColor blackColor];
