你好,
我在向UIBarButtonItem添加自定义操作时遇到问题
目标没有打电话
有人看到了这个问题吗？
let navBarMapImageView = UIImageView(frame: CGRect(x: 0,y: 0,width: 22,height: 22))
navBarMapImageView.contentMode = .scaleAspectFit
navBarMapImageView.image = image
navBarMapImageView.isUserInteractionEnabled = true
navBarMapImageView.target(forAction: #selector(openMaps),withSender: self)
let navBarMapButton = UIBarButtonItem(customView: navBarMapImageView)
感谢帮助
解决方法
你正在向UIImageView添加目标,它不起作用请检查下面的代码
let btn1 = UIButton(type: .custom)
btn1.setImage(UIImage(named: "imagename"),for: .normal)
btn1.frame = CGRect(x: 0,width: 30,height: 30)
btn1.addTarget(self,action: #selector(openMaps),for: .touchUpInside)
let item1 = UIBarButtonItem(customView: btn1)
self.navigationItem.setRightBarButtonItems([item1],animated: true)
