我有一个以编程方式创建的UIButton。我如何让这个UIButton将其补足事件发送给我的IBAction？

addTarget:action:forControlEvents:方法。

[myButton addTarget:myClass action:@selector(myEventHandler) forControlEvents: UIControlEventTouchUpInside];

使用这行代码，您将通过编程方式触发UI按钮操作

[button sendActionsForControlEvents:UIControlEventTouchUpInside];

您还可以发送发件人以识别触摸的按钮。另外，不要忘记在函数名称之前添加objc：

private func setOnClicks() {
    btn.addTarget(self, action: #selector(onBtnClick), for: .touchUpInside)
}

@objc func onBtnClick(_ sender: UIButton) -> Void {
    print("touched \(sender.tag)")
}

使用UIButton轻松设置addTarget(,action:,for:)的添加操作

let addVehicleButton = UIButton() // Create a button
addVehicleButton.setTitle("Add vehicle", forState: .normal) // set title
addVehicleButton.frame = CGRectMake(20, 50, 50, 40) // setting frame
addVehicleButton.addTarget(self, action: #selector(addVehicleButtonClickedAction), for: .touchUpInside) // Add target and control event with trigger function selector
self.view.addSubview(addVehicleButton) // adding to superview

//标记：-单击操作手柄

/// Add vehicle button clicked action
    @objc func addVehicleButtonClickedAction() {

    }
