  您可以使用 -[UIButton setTitleColor:forState:] 执行此操作 .

  例：

  Objective-C

  [buttonName setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
  

  Swift 2

  buttonName.setTitleColor(UIColor.blackColor(), forState: .Normal)
  

  Swift 3

  buttonName.setTitleColor(UIColor.white, for: .normal)

  你创建的 UIButton 添加了 ViewController ，以下实例方法改变了 UIFont ， tintColor 和 TextColor 的 UIButton

  Objective-C

  buttonName.titleLabel.font = [UIFont fontWithName:@"LuzSans-Book" size:15];
   buttonName.tintColor = [UIColor purpleColor];
   [buttonName setTitleColor:[UIColor purpleColor] forState:UIControlStateNormal];
  

  Swift

  buttonName.titleLabel.font = UIFont(name: "LuzSans-Book", size: 15)
  buttonName.tintColor = UIColor.purpleColor()
  buttonName.setTitleColor(UIColor.purpleColor(), forState: .Normal)
  

  Swift3

  buttonName.titleLabel?.font = UIFont(name: "LuzSans-Book", size: 15)
  buttonName.tintColor = UIColor.purple
  buttonName.setTitleColor(UIColor.purple, for: .normal)

  Solution in Swift 3 ：

  button.setTitleColor(UIColor.red, for: .normal)
  

  这将设置按钮的 Headers 颜色 .

  如果您使用Swift，这将做同样的事情：

  buttonName.setTitleColor(UIColor.blackColor(), forState: .Normal)

  希望有所帮助！

  使用Swift 3， UIButton 具有setTitleColor(_:for:)方法 . setTitleColor(_:for:) 有以下声明：

  func setTitleColor(_ color: UIColor?, for state: UIControlState)
  

  设置要用于指定状态的 Headers 的颜色 .

  以下Playground代码显示如何在 UIViewController 中创建 UIbutton 并使用 setTitleColor(_:for:) 更改其 Headers 颜色：

  import UIKit
  import PlaygroundSupport
  
  class ViewController: UIViewController {
  
      override func viewDidLoad() {
          super.viewDidLoad()
          view.backgroundColor = UIColor.white
  
          // Create button
          let button = UIButton(type: UIButtonType.system)
  
          // Set button's attributes
          button.setTitle("Print 0", for: UIControlState.normal)
          button.setTitleColor(UIColor.orange, for: UIControlState.normal)
  
          // Set button's frame
          button.frame.origin = CGPoint(x: 100, y: 100)
          button.sizeToFit()
  
          // Add action to button
          button.addTarget(self, action: #selector(printZero(_:)), for: UIControlEvents.touchUpInside)
  
          // Add button to subView
          view.addSubview(button)
      }
  
      func printZero(_ sender: UIButton) {
          print("0")
      }
  
  }
  
  let controller = ViewController()
  PlaygroundPage.current.liveView = controller
  

  在Playground中选择 Show the Assistant Editor > Timeline <Name of the page>.xcplaygroundpage 以显示 UIViewController 已创建的实例 .
