更改 UIBarButtonItem 的字体颜色

Changing font color of UIBarButtonItem

我尝试将右侧栏按钮项的字体颜色更改为紫色,但它仍然显示为白色。我咨询过这个question and this 。我该如何解决这个问题?

代码

let sortButton = UIButton(frame: CGRect(x: 0, y: 0, width: 34, height: 15))
    sortButton.setTitle("SORT", for: .normal)
    sortButton.titleLabel?.tintColor = UIColor.myMusicPurple
    sortButton.tintColor = UIColor.myMusicPurple        
    navigationItem.rightBarButtonItem =  UIBarButtonItem(customView: sortButton)
    navigationItem.rightBarButtonItem?.tintColor = UIColor.myMusicPurple

这应该可以解决问题(如果您有纯文本)

let rightBarButtonItem = UIBarButtonItem(title: "Some text", style: .plain, target: self, action: #selector(someAction))
rightBarButtonItem.tintColor = UIColor.myMusicPurple

navigationItem.rightBarButtonItem = rightBarButtonItem

如何使用:

func setTitleColor(UIColor?, for: UIControlState)

文档说它设置了用于指定状态的标题颜色。

sortButton.setTitleColor( .red, for: .normal)

请试试这个

sortButton.setTitleTextAttributes([NSAttributedStringKey.foregroundColor : UIColor.white], for: .normal)

很简单,只需为 UIBarButtonItem 创建一个从 Main.stroyboard 到相应的 swift 文件的引用,

@IBOutlet var yourBarBtn: UIBarButtonItem!

之后写下这一行,

yourBarBtn.tintColor = .white //your_color

就是这样!

首先需要设置plain properties 然后就可以这样写了

  @IBOutlet weak var btnGenerate: UIBarButtonItem!

  btnGenerate.setTitleTextAttributes([NSAttributedString.Key.foregroundColor : UIColor.colorBlue], for: .normal)
