Answer 1

这样试试。

在您的 class var settingRightBarButton : UIBarButtonItem?

中创建一个栏按钮属性

然后

let shareBarButtonImage = UIImage(named: "settings")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
self.settingRightBarButton = UIBarButtonItem(image: shareBarButtonImage, style: UIBarButtonItemStyle.Plain, target: self, action: Selector("didTapSettingButton"))
self.navigationItem.rightBarButtonItem = self.settingRightBarButton

在 Images.xcassets

中添加您的图片

Answer 2

试试这个代码：

var image : UIImage? = UIImage(named:"settings.png").imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)

Answer 3

设置图片UIImageRenderingMode属性:

 self.navigationItem.rightBarButtonItem =  UIBarButtonItem(image: UIImage(named: "settings.png").imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal), style: .Plain, target: self, action: "didTapSettingButton")
