UIBarButtonItem background image and setting action

I created button in navigation bar with this code:

UIBarButtonItem *myButtonEn = [[UIBarButtonItem alloc] initWithTitle:@"EN" style:UIBarButtonItemStyleDone target:self action:@selector(buttonEN:)];

My action for this button:

- (void) buttonEN:(id)sender {
  NSLog(@"English language"); 
}

This works fine but I have to change background and button's style (code below).

UIImage *imageEN = [UIImage imageNamed:@"cys_lang_en.png"];
UIButton *buttonImgEN = [UIButton buttonWithType:UIButtonTypeCustom];
buttonImgEN.bounds = CGRectMake( 0, 0, imageEN.size.width, imageEN.size.height );
[buttonImgEN setImage:imageEN forState:UIControlStateNormal];
UIBarButtonItem *myButtonEn = [[UIBarButtonItem alloc] initWithCustomView:buttonImgEN];

This is axactly what I need, but I need to set action

[myButtonEn setTarget:self];
[myButtonEn setAction:@selector(buttonEN:)];

This code is compiled with no errors but button does not respond.

Does anyone know what is wrong?

    [btn setImage:[UIImage imageNamed:@"cys_lang_en.png"] forState:UIControlStateNormal];
    UIBarButtonItem *eng_btn = [[UIBarButtonItem alloc] initWithCustomView:btn];

You are Missing action and target for button

You can set using,

[myButtonEn setTarget:self];
[myButtonEn setAction:@selector(buttonEN:)];

You might want to change apperance of this button. 

[[UIBarButtonItem appearance] setBackgroundImage:<doneBackgroundImage>
                                            forState:UIControlStateNormal
                                               style:UIBarButtonItemStyleDone
                                          barMetrics:UIBarMetricsDefault];

You don't need to use custom view for image, Try to use:

UIBarButtonItem *btn = [[UIBarButtonItem alloc] initWithImage:yourImage style:UIBarButtonItemStylePlain target:target action:@selector(selector)];
