如何在导航栏Swift右侧添加自定义视图？
我正在尝试在UINavigationBar的右侧添加自定义视图 。 我尝试的是以下内容，但视图没有显示出来！ 请帮助，提前谢谢！
let viewOnrightButton = UIView(frame: CGRect(x: 2, y: 2, width: 60, height: 22)) // viewOnrightButton.frame = CGRectMake(2, 2, 60, 22) viewOnrightButton.layer.cornerRadius = 2 viewOnrightButton.backgroundColor = UIColor(red: 0.961, green: 0.827, blue: 0.239, alpha: 1.00) lblNumbersOfBanana.frame = CGRectMake(2, 1, viewOnrightButton.frame.width-20, 20) lblNumbersOfBanana.text = "001" var bananaImgView = UIImageView(frame: CGRect(x: viewOnrightButton.frame.width-22, y: 0, width: 20, height: 20)) // bananaImgView.frame = CGRectMake(viewOnrightButton.frame.width-22, 0, 20, 20) bananaImgView.image = UIImage(named: "banana") viewOnrightButton.addSubview(lblNumbersOfBanana) viewOnrightButton.addSubview(bananaImgView) self.navigationItem.rightBarButtonItem?.customView = viewOnrightButton //创建uiview并添加三个自定义按钮
func addRightButton(){ let viewFN = UIView(frame: CGRectMake(0, 0, 180,40)) viewFN.backgroundColor = UIColor.yellowColor() let button1 = UIButton(frame: CGRectMake(0,8, 40, 20)) button1.setImage(UIImage(named: "notification"), forState: UIControlState.Normal) button1.setTitle("one", forState: .Normal) button1.addTarget(self, action: #selector(self.didTapOnRightButton), forControlEvents: UIControlEvents.TouchUpInside) let button2 = UIButton(frame: CGRectMake(40, 8, 60, 20)) button2.setImage(UIImage(named: "notification"), forState: UIControlState.Normal) button2.setTitle("tow", forState: .Normal) let button3 = UIButton(frame: CGRectMake(80, 8, 60, 20)) button3.setImage(UIImage(named: "notification"), forState: UIControlState.Normal) button3.setTitle("three", forState: .Normal) button3.addTarget(self, action: #selector(self.didTapOnRightButton), forControlEvents: UIControlEvents.TouchUpInside) viewFN.addSubview(button1) viewFN.addSubview(button2) viewFN.addSubview(button3) let rightBarButton = UIBarButtonItem(customView: viewFN) self.navigationItem.rightBarButtonItem = rightBarButton }
你可以这样做，试试吧：
var view = UIView(frame: CGRectMake(0, 0, 100, 44)) view.backgroundColor = UIColor.yellowColor() var barButtonItem = UIBarButtonItem(customView: view) self.navigationItem.rightBarButtonItem = barButtonItem
Swift 3/4版本的公认答案
let viewFN = UIView(frame: CGRect.init(x: 0, y: 0, width: 180, height: 40)) viewFN.backgroundColor = .yellow let button1 = UIButton(frame: CGRect.init(x: 0, y: 0, width: 40, height: 20)) button1.setImage(UIImage(named: "notification"), for: .normal) button1.setTitle("one", for: .normal) button1.addTarget(self, action: #selector(self.didTapOnRightButton), for: .touchUpInside) let button2 = UIButton(frame: CGRect.init(x: 40, y: 8, width: 60, height: 20)) button2.setImage(UIImage(named: "notification"), for: .normal) button2.setTitle("tow", for: .normal) let button3 = UIButton(frame: CGRect.init(x: 80, y: 8, width: 60, height: 20)) button3.setImage(UIImage(named: "notification"), for: .normal) button3.setTitle("three", for: .normal) button3.addTarget(self, action: #selector(self.didTapOnRightButton), for: .touchUpInside) viewFN.addSubview(button1) viewFN.addSubview(button2) viewFN.addSubview(button3) let rightBarButton = UIBarButtonItem(customView: viewFN)
希望它可以帮到某人。 干杯!
我假设你的rigthtBarButtonItem是零。 而是使用您的自定义视图初始化一个新的UIBarButtonItem并将其设置为rightBarButtonItem。 试一试
这是一个按钮的示例：
// Right Side let rubricButton = UIButton.buttonWithType(UIButtonType.System) as! UIButton rubricButton.frame = CGRectMake(0, 0, 100, 32) // Size rubricButton.backgroundColor = UIColor.clearColor() rubricButton.setTitle("Options", forState: UIControlState.Normal) rubricButton.titleLabel!.font = UIFont(name: "Lato-Regular", size: 18) rubricButton.addTarget(self, action: "showRubricList:", forControlEvents: UIControlEvents.TouchUpInside) // Action var rubricBarButtonItem: UIBarButtonItem = UIBarButtonItem(customView: rubricButton) // Create the bar button // Add the component to the navigation Bar self.navigationItem.setRightBarButtonItems([rubricBarButtonItem], animated: false)
我在viewWillAppear（）中添加了这段代码，并为我工作
override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(animated) self.navigationController?.navigationBar.isHidden = false self.navigationItem.title = "Forgot Password?" self.navigationItem.leftBarButtonItem = UIBarButtonItem(customView:UIImageView(image: UIImage(named: "btn_back"))) }
