Setting Bar Button Item color in a custom navigation bar

问题

I created a custom navigation bar and a right navigation button using the XIB. This works fine. But I need to to customize the tint color of the right navigation button. At the moment this tint color is the same color as tint color of navigation bar. I need a different color for this right button. Is there any way to change this color?

Thank you.

Not to my knowledge, the button inherits the tint color of the navigationBar. What you can do is set a customView for the navigationItem:

This is how you set it with one of the SDK's buttons:

UIBarButtonItem *shareButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:@selector(shareButtonHandler:)];

[self.navigationItem setRightBarButtonItem:shareButton];
[shareButton release];

Instead you can do it like this:

UIBarButtonItem *btn = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"yourImage.png" style:UIBarButtonItemStyleBordered target:self action:@selector(customButtonHandler:)]];

To use an image you made in photoshop etc.

There is als an initWithCustomView:UIView or initWithTitle:NSString you can use.

Sorry no "one-line solution" :)

In iOS 5 there is 'appearance' feature:

[[UIBarButtonItem appearance] setTintColor:YOUR_COLOR];

Swift 3.x

UIBarButtonItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName : Color.primaryActionColor], for: .normal)

If you have navigation bar button item with custom view you should convert to UIButton first:

navigationItem.rightBarButtonItem?.customView as? UIButton

Then you can add the attributes of UIButton such as:

button.setTitleColor(UIColor.black.withAlphaComponent(0.1), for: .normal)
