如何从Xcode / Swift中的滚动视图中删除后退按钮

Question

I am trying to remove the automatically generated back button from my scrollview in Xcode. Thanks.

You are using an UINavigationController , the UIScrollView not have any UINavigationBar inside it. You need to set a normal UIViewController or hide the back button in your UINavigationBar in the following way:

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

Or in this way :

let backButton = UIBarButtonItem(title: "", style: UIBarButtonItemStyle.Plain, target: navigationController, action: nil)
self.navigationItem.leftBarButtonItem = backButton

I hope this help you.
