I am not sure but if you want to apply the different colors to left and right bar buttons then just try to apply the tintColor
independently and remove the line that sets the tintColor
to navigationBar
. Just try it.
Update :
It looks like Apple don't want us to apply the different color on left and right bar buttons anymore. Behavior from some of the properties of UINavigationBar
has changed from iOS 7
. I have already given description in my Answer, you can check it.
