How to remove add-on next to UIBarButtonItem

I added a custom button to the custom panel of the right button of the navigation bar, as shown in the figure.

I want to remove the space after the button so that it touches the right edge of the screen, but cannot find a solution even after searching. If someone could mention how cool it would be.

This is the code I'm using.

UIButton *aButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];    
aButton.frame = CGRectMake(50.0, 0.0, 60, 44);
UIBarButtonItem *aBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:aButton];
[aButton addTarget:self action:@selector(testButtonControl:) forControlEvents:UIControlEventTouchUpInside];

self.navigationItem.rightBarButtonItem = aBarButtonItem;

enter image description here

You need to create a new view, add a button and everything else you want, and add it to the title as shown.

- (void)viewDidLoad {
    self.navigationItem.titleView = [self titleView];
}

- (UIView *)titleView {
    CGFloat navBarHeight = self.navigationController.navigationBar.frame.size.height;
    CGFloat width = 0.95 * self.view.frame.size.width;
    UIView *containerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, width, navBarHeight)];
..
// please add what you need here
....
}

You can add a fixed-space element with a negative width (I know this sounds like a hack, but it works):

UIButton *aButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];    
aButton.frame = CGRectMake(50.0, 0.0, 60, 44);
UIBarButtonItem *aBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:aButton];
[aButton addTarget:self action:@selector(testButtonControl:) forControlEvents:UIControlEventTouchUpInside];

UIBarButtonItem *spaceFix = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:NULL];
spaceFix.width = -5;

self.navigationItem.rightBarButtonItems = @[spaceFix, aBarButtonItem];

You can do this by adding a UIView, then add your button inside it with x = spaceWidth y = 0.

see below the code for the correct item (this is inside the UINavigationItem category)

1 -

UIView *_rightView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 44, 44)]; [_rightView setBackgroundColor:[UIColor purpleColor]];//debug color

2-

    UIButton *aLeftButton = [[UIButton alloc] init];

   //...//

    aLeftButton.frame = CGRectMake(-15, 0, 44, 44);//in your case +15
    [aLeftButton setBackgroundImage:[UIImage imageNamed:buttonName] forState:UIControlStateNormal];
    [aLeftButton setBackgroundImage:[UIImage imageNamed:[buttonName stringByAppendingString:@"Selected"]] forState:UIControlStateSelected];
    [aLeftButton setAdjustsImageWhenDisabled:NO];
    [aLeftButton setAdjustsImageWhenHighlighted:NO];

    [aLeftButton addTarget:theSender action:aSelector forControlEvents:UIControlEventTouchUpInside];
    [_rightView addSubview:aLeftButton];
    UIBarButtonItem *aBarButton = [[UIBarButtonItem alloc] initWithCustomView:_rightView];
    [leftBarButtonsItem addObject:aBarButton];`

self.leftBarButtonItem = leftBarButtonsItem;
