使用Swift创建调用UITapGestureRecognizer函数的UIBarButton可以通过以下步骤实现:
override func viewDidLoad() {
super.viewDidLoad()
let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(handleTap(_:)))
let barButtonItem = UIBarButtonItem(title: "Tap", style: .plain, target: self, action: #selector(handleTap(_:)))
navigationItem.rightBarButtonItem = barButtonItem
barButtonItem.customView?.addGestureRecognizer(tapGestureRecognizer)
}
@objc func handleTap(_ sender: UITapGestureRecognizer) {
// 处理点击手势触发的事件
print("UIBarButtonItem tapped!")
}
通过以上步骤,你可以使用Swift创建一个调用UITapGestureRecognizer函数的UIBarButton。当用户点击该UIBarButtonItem时,handleTap方法将被调用,并执行相应的操作。
