问题描述

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.我已经咨询过这个问题和这个问题.我该如何解决这个问题?

I tried to change the font color of the right bar button item to purple, but it still shows up as white. I've consulted this question and this question. How do I fix this?

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

推荐答案

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.

Documentation says it sets the color of the title to use for the specified state.

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