11/6/2018 The lastest way
It is the best way to hide left back title of the navigation bar so far.
class YGCustomNavigationVC: UINavigationController {
override func viewDidLoad() {
super.viewDidLoad()
self.delegate = self
}
}
extension YGCustomNaviVC:UINavigationControllerDelegate {
func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {
let item = UIBarButtonItem(title: " ", style: .plain, target: nil, action: nil)
viewController.navigationItem.backBarButtonItem = item
}
}

iOS 全局修改UINavigationBar的返回按钮（适配 iOS 11）
This way is no pefect when A viewcontroller which has hidden navigation bar push to B viewcontroller which will show it.
It won't hide left back title of the navigation bar in iOS11

The following code do work perfectly before iOS11, If you want hide back title of the navigation bar.
UIBarButtonItem.appearance()
.setBackButtonTitlePositionAdjustment(UIOffsetMake(0,-300), for:UIBarMetrics.default)
