我需要在导航栏中显示我的应用程序图标.为此,我将其添加为右键按钮项.我不希望它是可点击的,我只需要那里的图标,所以我将它设置为禁用.这个问题是图标显示为灰色,而不是绿色.有没有办法禁用此按钮,但也保持原始颜色？
解决方法
试试这个：
let barButtonItem = UIBarButtonItem(title: "Click",style: .Done,target: self,action: #selector(didClick(_:)))
barButtonItem.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.blueColor()],forState: .Normal)
barButtonItem.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.blueColor()],forState: .Disabled)
barButtonItem.enabled = false
navigationItem.setRightBarButtonItem(barButtonItem,animated: false)
