_searchBar = UISearchBar(frame: CGRect(frame: CGRect(x: 0, y: 0, width: 414, height: 64))) 
_searchBar!.delegate = self 
_searchBar!.showsCancelButton = true 
backgroundColor = .white 
barTintColor = .white

看到这个曾经https://stackoverflow.com/questions/35302760/如何改变取消按钮上的uisearchbar-in-swift –

使用appearance功能UIAppearance模块 -

方法1： -可见取消按钮的颜色，当searchBar上负载

let attributes = [NSForegroundColorAttributeName : UIColor.red] 
    UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).setTitleTextAttributes(attributes, for: .normal)

或 -

方法2： - 可见取消按钮颜色searchBar点击后 -

UIBarButtonItem.appearance(whenContainedInInstancesOf:[UISearchBar.self]).tintColor = UIColor.red

@ Jack非常感谢你，这是工作，但它必须iOS9.0，@ Anbu.Karthink答案适用于t o所有系统版本 –

让cancelButtonAttributes: NSDictionary = [NSForegroundColorAttributeName: ``UIColor.YOUR COLOR] UIBarButtonItem.appearance().setTitleTextAttributes(cancelButtonAttributes as?[String : AnyObject], forState: UIControlState.Normal)

在你的地方你的颜色ADD UIColor.YOUR COLOR –

改变了格式可读性

let cancelButtonAttributes: NSDictionary = [NSForegroundColorAttributeName: UIColor.YOUR COLOR]  UIBarButtonItem.appearance().setTitleTextAttributes(cancelButtonAttributes as? [String : AnyObject], forState: UIControlState.Normal)
