Try this code:

UIImage* image3 = [UIImage imageNamed:@"mail-48_24.png"];
CGRect frameimg = CGRectMake(0, 0, image3.size.width, image3.size.height);
UIButton *someButton = [[UIButton alloc] initWithFrame:frameimg];
[someButton setBackgroundImage:image3 forState:UIControlStateNormal];
[someButton addTarget:self action:@selector(sendmail)
     forControlEvents:UIControlEventTouchUpInside];
[someButton setShowsTouchWhenHighlighted:YES];

UIBarButtonItem *mailbutton =[[UIBarButtonItem alloc] initWithCustomView:someButton];
self.navigationItem.rightBarButtonItem=mailbutton;
[someButton release];

UIBarButtonItem *btnNext =[[UIBarButtonItem alloc] initWithCustomView:btnNext1];
[btnNext1 addTarget:self action:@selector(nextButtonClicked) forControlEvents:UIControlEventTouchUpInside];

 UIBarButtonItem *_btn=[[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@"XXXXXXX.png"] 
                                                  style:UIBarButtonItemStylePlain 
                                                  target:self 
                                                  action:@selector(yourMethod)];

self.navigationItem.rightBarButtonItem=_btn;

Answer 5

To pick up on the answer by Gurpreet Singh. To keep the current status of an already existing button re-use the target and action.

SEL selector = self.navigationItem.rightBarButtonItem.action;
id target = self.navigationItem.rightBarButtonItem.target;
UIBarButtonItem *_btn=[[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@"icon_close.png"]
                                                      style:UIBarButtonItemStylePlain
                                                     target:target
                                                     action:selector];

self.navigationItem.rightBarButtonItem = _btn;

Answer 6

One simple way :

UIImage* customImg = [UIImage imageNamed:@"custom-img.png"];

UIBarButtonItem *_customButton = [[UIBarButtonItem alloc] initWithImage:customImg style:UIBarButtonItemStyleDone target:nil action:nil];

self.navigationItem.rightBarButtonItems = [[NSArray alloc] initWithObjects:_customButton, nil];

Then if you need more than one button you can just and an other UIBarButtonItem to initWithObjects.
