rightBarButtonItem not changing color when its disabled in iOS8

Question

disabling the rightBarButtonItem in iOS8 is not changing its color to grey like in iOS7.Do I have to do anything more to change its color when disabled, other than changing text color color manually.

Answer 1

I found an alternative myself. This can be done as follows:

[self.navigationItem.rightBarButtonItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys: [UIColor grayColor], NSForegroundColorAttributeName, nil] forState:UIControlStateDisabled];
