如何在Swift 3中設置editButtonItem標題

Question

我知道在Swift 2.2中很容易。就像這樣：

editButtonItem().title = "My Title" 

但是在斯威夫特3，editButtonItem成爲UIViewController的屬性。而且UIBarButtonItem不再有標題。所以這是行不通的：

editButtonItem.title = "My Title" // doesn't work 

請幫我這個！謝謝！

1. 這可能對你有幫助！

   let navigationBar = navigationController!.navigationBar 
   navigationBar.tintColor = UIColor.blueColor() 
   
   let leftButton = UIBarButtonItem(title: "Left Button", style: UIBarButtonItemStyle.Plain, target: self, action: nil) 
   navigationItem.leftBarButtonItem = leftButton
