How to remove NavigationBar Right space?

Question

I'm playing with Navigation Bar Buttons I need a button from right edge with 0 space, after google search i found below code

 self.filterButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 80, 45)];
[self.filterButton setBackgroundColor:[UIColor redColor]];
UIImage *buttnImage=[UIImage imageNamed:@"chemistry-filter"];
[self.filterButton setImage:buttnImage forState:UIControlStateNormal];
[self.filterButton addTarget:self action:@selector(filterAction:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *btn2 = [[UIBarButtonItem alloc] initWithCustomView:self.filterButton];

UIBarButtonItem *negativeSpacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
negativeSpacer.width = -25;
[self.navigationItem setRightBarButtonItems:[NSArray arrayWithObjects:negativeSpacer,btn2, nil] animated:YES];

But unfortunatly in iOS 13 negativeSpacer not working. can anybody suggest me solutions.

Attached screenshot here Thanks.

So u don't want the white space as it is seen on the right side of the button right ? — zenwraight, May 01 '20 at 05:18
you can make use of constraints also, like leading anchor, trailing anchor, bottom anchor and top anchor. And that way it attaches to the corner — zenwraight, May 01 '20 at 05:42

Let's try this easy way, Let's define the width of space BarButtonItem to be width of self.view.frame.size.width - width of the button.

self.filterButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 80, 45)];
[self.filterButton setBackgroundColor:[UIColor redColor]];
UIImage *buttnImage=[UIImage imageNamed:@"chemistry-filter"];
[self.filterButton setImage:buttnImage forState:UIControlStateNormal];
[self.filterButton addTarget:self action:@selector(filterAction:) 
forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *btn2 = [[UIBarButtonItem alloc] 
initWithCustomView:self.filterButton];

UIBarButtonItem *negativeSpacer = [[UIBarButtonItem alloc] 
initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil 
action:nil];
negativeSpacer.width = self.view.frame.size.width - 45; // As 45 is the frame width of your filter button 
[self.navigationItem setRightBarButtonItems:[NSArray 
arrayWithObjects:negativeSpacer,btn2, nil] animated:YES];

Hope this helps!

tried with negative value like '-(self.view.frame.size.width - 130)' still in same place like attached image in question — Bittoo, May 01 '20 at 06:39
