How to add custom image in navigation bar button item?

Answer 1

Here's what works for me. I found 30x30 to be a good size for the button in the nav bar. The UIImage scales to the button size automatically.

UIImage *image = [UIImage imageNamed:@"XXXXXXXXXX"];
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 30, 30)];
[button setBackgroundImage:image forState:UIControlStateNormal];
[button addTarget:self action:@selector(someAction) forControlEvents:UIControlEventTouchUpInside];
button.adjustsImageWhenHighlighted = NO;
UIBarButtonItem *rightButton =[[UIBarButtonItem alloc] initWithCustomView:button];
self.navigationItem.rightBarButtonItem = rightButton;
