Hide back button code in objective-c

回答1:

From the UINavigationItem class reference documentation -

self.navigationItem.setHidesBackButton(true, animated:true);

回答2:

In case you're using a UITabBarController:

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    self.tabBarController?.navigationItem.hidesBackButton = true
}

回答3:

This is also found in the UINavigationController class documentation:

navigationItem.hidesBackButton = true

回答4:

Swift

// remove left buttons (in case you added some)
 self.navigationItem.leftBarButtonItems = []
// hide the default back buttons
 self.navigationItem.hidesBackButton = true

You may try with the below code

override func viewDidAppear(_ animated: Bool) {
    self.navigationController?.isNavigationBarHidden = true
}

Go to attributes inspector and uncheck show Navigation Bar to hide back button.
