How to add an image to UIBarButtonItem? - objective-c

Question

I created a custom button and applied it to the UIbarbuttonitem.
There is no error but nothing is shown on the navigation bar:(
This is my code-
//create a custom button
UIImage *image = [UIImage imageNamed:#"TESTButton.png"];
UIButton *myCustomButton = [UIButton buttonWithType:UIButtonTypeCustom];
myCustomButton.bounds = CGRectMake( 0, 0, image.size.width, image.size.height );
[myCustomButton setImage:image forState:UIControlStateNormal];
[myCustomButton addTarget:nil action:#selector(goBack:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithCustomView:myCustomButton];
self.navigationItem.leftBarButtonItem = button;
self.navigationController.navigationBar.barStyle = UIBarStyleDefault;
[button release];
[myCustomButton release];
[image release];
[navID release];
Anybody who can fix my code? :)

Answer 1

From the docs:
initWithImage:style:target:action:
Try that.

Answer 2

To set ANY image with right coloring, use UIButton, set "image for state" and then create UIBarButtonItem with customView
UIImage *btnImage = [UIImage imageNamed:#"button"];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.bounds = CGRectMake( 0, 0, btnImage.size.width, btnImage.size.height );
[btn addTarget:self action:#selector(action:) forControlEvents:UIControlEventTouchDown];
[btn setImage:btnImage forState:UIControlStateNormal];
_buttonItem = [[UIBarButtonItem alloc] initWithCustomView:btn];

Answer 3

One of the Simplest Way is :
UIBarButtonItem *button2 = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"backk.png"] style:UIBarButtonItemStylePlain target:self action:#selector(backBtn:)];
self.navigationItem.leftBarButtonItem = button2;
Action Method:
- (IBAction)backBtn:(id)sender
{
[self.navigationController popViewControllerAnimated:YES];
}
