A UIViewController category that can make the navigation bar transparent

Description

UIViewController+TransparentNavBar is a category that allows you to set your UINavigationBar background to transparent or to any UIColor you choose.

Because its a UIViewController category, the UINavigationBar background can be changed each time a UIViewController is pushed or popped into the navigation hierarchy.

How to install

Add this to your CocoaPods Podfile.

pod 'UIViewController-TransparentNavBar'

How to use

In your UIViewController

#import "UIViewController+TransparentNavBar.h"

- (void)viewWillAppear:(BOOL)animated {
    // to set transparent
    [self setNavBarColor:[UIColor clearColor]];
    
    // to set a custom color
    [self setNavBarColor:[UIColor yellowColor]];

    // to set back to default grey color
    [self setNavBarColor:nil];
}
