我已经坚持了好几天了。我的rightBarButtonItem有问题。我想创建一个自定义视图。在自定义视图中,有2个项目:标签,imageView。当我输入以下内容时:
let customView = UIView()
customView.translatesAutoresizingMaskIntoConstraints = false
customView.backgroundColor = .black
customView.frame = CGRect(x: 0, y: 0, width: 90, height: 40)
let coinLabelNavigationBar = UILabel()
coinLabelNavigationBar.frame = CGRect(x: 40, y: 0, width: 30, height: 25)
coinLabelNavigationBar.translatesAutoresizingMaskIntoConstraints = false
coinLabelNavigationBar.text = "200"
coinLabelNavigationBar.font = UIFont(name: ".SFUIText-Medium", size: 20)
coinLabelNavigationBar.textColor = UIColor.white
let coinImage = UIImageView()
coinImage.frame = CGRect(x: 75, y: 0, width: 25, height: 25)
coinImage.translatesAutoresizingMaskIntoConstraints = false
coinImage.image = UIImage(named: "Coin")
customView.addSubview(coinLabelNavigationBar)
customView.addSubview(coinImage)
let rightBarButton = UIBarButtonItem(customView: customView)
navigationItem.rightBarButtonItem = rightBarButton
您有什么主意,如何解决?
感谢您的回答。

尝试-
let customView = UIView()
// customView.translatesAutoresizingMaskIntoConstraints = false
customView.backgroundColor = .black
customView.frame = CGRect(x: 0, y: 0, width: 90, height: 40)
let coinLabelNavigationBar = UILabel()
coinLabelNavigationBar.frame = CGRect(x: 40, y: 0, width: 30, height: 25)
// coinLabelNavigationBar.translatesAutoresizingMaskIntoConstraints = false
coinLabelNavigationBar.text = "200"
coinLabelNavigationBar.font = UIFont(name: ".SFUIText-Medium", size: 20)
coinLabelNavigationBar.textColor = UIColor.white
let coinImage = UIImageView()
coinImage.frame = CGRect(x: 75, y: 0, width: 25, height: 25)
// coinImage.translatesAutoresizingMaskIntoConstraints = false
coinImage.image = UIImage(named: "coin.jpg")
customView.addSubview(coinLabelNavigationBar)
customView.addSubview(coinImage)
let rightBarButton = UIBarButtonItem(customView: customView)
navigationItem.rightBarButtonItem = rightBarButton

对于Swift 3.0:
let btn1 = UIButton(type: .custom)
btn1.setImage(UIImage(named: "imagename"), for: .normal)
btn1.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
btn1.addTarget(self, action: #selector(Class.Methodname), for: .touchUpInside)
let item1 = UIBarButtonItem(customView: btn1)
let btn2 = UIButton(type: .custom)
btn2.setImage(UIImage(named: "imagename"), for: .normal)
btn2.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
btn2.addTarget(self, action: #selector(Class.MethodName), for: .touchUpInside)
let item2 = UIBarButtonItem(customView: btn2)
self.navigationItem.setRightBarButtonItems([item1,item2], animated: true)
