Change position of UIBarButtonItem in UINavigationBar

by

This code creates a back button for UINavigationBar with image background and custom position. The trick is to create an intermediate view and modify its bounds.

Swift 5

let menuBtn = UIButton(type: .custom)
let backBtnImage = UIImage(named: "menu")

menuBtn.setBackgroundImage(backBtnImage, for: .normal)
menuBtn.addTarget(self, action: #selector(showMenuTapped), for: .touchUpInside)
menuBtn.frame = CGRect(x: 0, y: 0, width: 45, height: 45)

let view = UIView(frame: CGRect(x: 0, y: 0, width: 45, height: 45))
view.bounds = view.bounds.offsetBy(dx: 10, dy: 3)
view.addSubview(menuBtn)
let backButton = UIBarButtonItem(customView: view)

navigationItem.leftBarButtonItem = backButton

Objective C

UIButton *backBtn = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *backBtnImage = [UIImage imageNamed:@"btn-back"];
UIImage *backBtnImagePressed = [UIImage imageNamed:@"btn-back-pressed"];
[backBtn setBackgroundImage:backBtnImage forState:UIControlStateNormal];
[backBtn setBackgroundImage:backBtnImagePressed forState:UIControlStateHighlighted];
[backBtn addTarget:self action:@selector(goBack) forControlEvents:UIControlEventTouchUpInside];
backBtn.frame = CGRectMake(0, 0, 63, 33);
UIView *backButtonView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 63, 33)];
backButtonView.bounds = CGRectOffset(backButtonView.bounds, -14, -7);
[backButtonView addSubview:backBtn];
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithCustomView:backButtonView];
self.navigationItem.leftBarButtonItem = backButton;
