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

使用appearance模块的UIAppearance功能 -

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

或 -

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

将格式更改为可读性

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