我已经尝试创建自己的UIBarButtonItem,但我无法弄清楚如何将图像放在文本旁边,而不是作为文本的背景或替代。
I've tried creating my own UIBarButtonItem but I can't figure out how to get the image to be beside the text, rather than as a background or a replacement for the text.
let backButton = UIBarButtonItem(title: "Custom", style: .Plain, target: self, action: nil )
//backButton.image = UIImage(named: "imageName") //Replaces title
backButton.setBackgroundImage(UIImage(named: "imageName"), forState: .Normal, barMetrics: .Default) // Stretches image
navigationItem.setLeftBarButtonItem(backButton, animated: false)
推荐答案
你可以做类似的事情:
let yourBackImage = UIImage(named: "back_button_image")
self.navigationController?.navigationBar.backIndicatorImage = yourBackImage
self.navigationController?.navigationBar.backIndicatorTransitionMaskImage = yourBackImage
self.navigationController?.navigationBar.backItem?.title = "Custom"
您的图片只有一种颜色,但
Your image will only have one color though
