barButton.tintColor=UIColor.white
self.navigationItem.rightBarButtonItem=barButton

Answer 1

您需要设置标题如下：

 customButton?.setTitle("Add", for:.normal)

Answer 2

您必须使用此：

[customButton setTitle:@"Add" forState:UIControlStateNormal];

Answer 3

Try This code:

Note: This is a better approach to apply barButton to your navigationBar with action.

 navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Add", style: .plain, target: self, action:  #selector(addTapped))

 func addTapped() {
    //Do your stuff here. After Add button pressed
    print("Add Button Pressed")
 }

If you still want to use your code.Add the following code to set title to your button as KKRocks answer.

  customButton?.setTitle("Add", for:.normal)
