remove space below the UITabBarItem? - ios

Question

how do I reduce the distance between the two items?
my code:
-(void)setupRightMenuButton{
filtro = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"icon-filtro-bar"] style:UIBarButtonItemStylePlain target:self action:#selector(buttonFilter)];
busca = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"icon-busca"] style:UIBarButtonItemStylePlain target:self action:#selector(moveToSearchView)];
filtro.tintColor = [UIColor whiteColor];
busca.tintColor = [UIColor whiteColor];
filtro.imageInsets = UIEdgeInsetsMake(6, 0, -6, 0);
busca.imageInsets = UIEdgeInsetsMake(6, 0, -6, 0);
[self.navigationItem setRightBarButtonItems:[NSArray arrayWithObjects:busca, filtro, nil] animated:YES];
}
My viewDidLoad:
- (void)viewDidLoad {
[super viewDidLoad];
[self setupLeftMenuButton];
[self.navigationController.navigationBar setBarTintColor: [UIColor colorWithRed:0.49 green:0.075 blue:0.082 alpha:1]]; /*#7d1315*/
[self.navigationController.navigationBar setTitleTextAttributes:#{NSForegroundColorAttributeName : [UIColor whiteColor]}];
self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(0, -60)
forBarMetrics:UIBarMetricsDefault];
[self setupRightMenuButton];
self.title = #"Músicas";
}
I tried using the filtro.imageInsets = UIEdgeInsetsMake (6, 0, -6, 0); but it did not work

Try to add buttons this way:
UIButton *but1 = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, width, height)];
UIView *but1View = [[UIView alloc] initWithFrame:CGRectMake(x, y, width, height)];
[but1View addSubview:but1];
UIBarButtonItem *rightButton1 = [[UIBarButtonItem alloc] initWithCustomView:but1View];
UIButton *but2 = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, width, height)];
UIView *but2View = [[UIView alloc] initWithFrame:CGRectMake(x, y, width, height)];
[but2View addSubview:but2];
UIBarButtonItem *rightButton2 = [[UIBarButtonItem alloc] initWithCustomView:but2View];
self.navigationItem.rightBarButtonItems=#[ rightButton,rightButton2];
you need to mention the postions of x and y for the both UIViews as where ou want your buttons on the nav bar.

This code works for me. Try to create a button, then set the image to it and set the buttons frame.
let button: UIButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
let image = UIImage(named: "your_image")!
button.setImage(image , forState: UIControlState.Normal)
// optional -------------
button.addTarget(self, action: "your_function", forControlEvents: UIControlEvents.TouchUpInside)
// ------------
button.frame = CGRectMake(0, 0, image.width, image.height)
let barButton = UIBarButtonItem(customView: button)
Create as many barButtons as you want and then add them to navigationItem:
self.navigationItem.setRightBarButtonItems([barBtn1, barBtn2], animated: false)
