跟踪iOS应用程序的任何用户交互

如何跟踪或捕获iOS应用程序的每个用户交互？就像按UIButton，UIBarButton。。。任何UIControl元素

---

我知道有数百种分析工具，如Google analytics、Flurry、Appsee等，但我想将这些数据保存在我自己的服务器上

Hello@tuvok如果你不想使用Google analytics和其他库，那么你必须制作一个API（Web服务）。您必须在每个用户交互上点击api，如按下按钮或其他任何操作。

您可以将UIApplication子类化：

• 创建UIApplication子类
• 覆盖 sendAction（action:Selector，to target:Any？，from sender:Any？，for event:UIEvent？ 事件方法，记住调用超级实现
• 将NSLog或其他诊断代码放入实施中

例如，这将在每次按下UIButton时打印日志：

func sendAction(_ action: Selector, to target: Any?, from sender: Any?, for event: UIEvent?) -> Bool {
    if (sender is UIButton) {
        print("Action: \(NSStringFromSelector(action)) - \(target) - \(sender)")
    }
    return super.sendAction(action, to: target, from: sender, for: event)
}

func sendAction（action:Selector，to target:Any？，from sender:Any？，for event:UIEvent？）->Bool{
如果（发送方为UIButton）{
打印（“操作：\（NSStringFromSelector（操作））-\（目标）-\（发送方）”）
}
返回super.sendAction（操作，收件人：目标，发件人：发件人，for:事件）
}

对于objective-c参考

找到了一个简单的解决方案：

1.创建一个UIControl扩展

private let swizzling: (AnyClass, Selector, Selector) -> () = { forClass, originalSelector, swizzledSelector in
    let originalMethod = class_getInstanceMethod(forClass, originalSelector)
    let swizzledMethod = class_getInstanceMethod(forClass, swizzledSelector)
    method_exchangeImplementations(originalMethod!, swizzledMethod!)
}

extension UIControl {

    static let classInit: Void = {
        let originalSelector = #selector(sendAction(_:to:for:))
        let swizzledSelector = #selector(swizzled_sendAction(_:to:for:))
        swizzling(UIControl.self, originalSelector, swizzledSelector)
    }()

    @objc func swizzled_sendAction(_ action: Selector, to target: Any?, for event: UIEvent?) {

        swizzled_sendAction(action, to: target, for: event)
        print("action was triggered")
    }
}

AppDelegate中的初始化：

@UIApplicationMain 类AppDelegate:UIResponder、UIApplicationLegate{

override init() {
    super.init()
    UIControl.classInit
}

示例如下：

您可以在单个文本文件中编写每个操作！将该文件保存在文档目录中。然后在每次应用程序启动时将该文件发送到您的服务器（使用API）！
