how to change the color of backBarButtonItem?

Question

In my application I want to change the color of bacBarButtonItem. Is it possible to change the color? or I have to put an image of it. and in case of image tell me the code how to put the image.

Answer 1

If you just want to change the color you can do it with this line of code.

[[UIBarButtonItem appearance] setTintColor:[UIColor redColor]];

Replace redColor with the following to adjust the color of the buttons:

colorWithRed:0/255.0 green:144/255.0 blue:200/255.0 alpha:1.0// pick your color using this

Be sure to put this in the view controller that pushes. Not the view controller where you want to see this back button color.

Answer 2

Praveen-K answer is right, but take in mind that you'll have to do it in every viewcontroller.

Starting at iOS5, Apple have introduced the "appearance" concept.

- (void)setBackButtonBackgroundImage:(UIImage *)backgroundImage forState:(UIControlState)state barMetrics:(UIBarMetrics)barMetrics __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_5_0) UI_APPEARANCE_SELECTOR;

In your case would be something like this

UIImage *image = [UIImage imageNamed:@"imageName.png"];
[[UIBarButtonItem appearance] setBackButtonBackgroundImage:image forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

But as I said, Praveen-K answer is ok and will work, but just to let you know for the future.
