Change color of translucent black UINavigationBar

Question

I stumbled upon this many times, never found a solution. A UINavigationController's navigationBar can be set to black translucent like:

self.navigationController.navigationBar.barStyle=UIBarStyleBlackTranslucent; 

Also, there is a translucent property in UINavigationBar, the docs say:

When YES, the navigation bar is drawn with partial opacity, regardless of the bar style. The amount of opacity is fixed and cannot be changed. It is permissible to set the value of this property when the navigation bar is being managed by a navigation controller object.

I tried

self.navigationcontroller.navigationBar.tintColor=[UIColor blueColor]; self.navigationcontroller.navigationBar.translucent=YES; 

and a thousand variations: Setting the translucent property first, setting it in the AppDelegate and in the ViewController, setting the barstyle first. The result is always the same: No transparency. Hence my question:

Is it really possible to change the color of a translucent UINavigationBar to something different than black (preferably within a UINavigationController)?.

I hope there is a review-safe solution.

Thanks, m

Once you know it, it's fairly simple:

self.navigationController.navigationBar.tintColor = [UIColor blueColor]; self.navigationController.navigationBar.alpha = 0.7f; self.navigationController.navigationBar.translucent = YES; 

The translucent property seems only to determine wether the main view should be visible under the navigation bar, and resizes the view appropiately.
