ios - 跟踪 iOS 应用程序的任何用户交互

Question

如何跟踪或捕捉我的 iOS 应用的每次用户交互？就像按下 UIButton、UIBarButton ……任何 UIControl 元素一样。

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。

您可以子类化 UIApplication:

• 创建一个 UIApplication 子类
• 覆盖 sendAction(_ action: Selector, to target: Any?, from sender: Any?, for event: UIEvent?) 事件方法，记得调用super实现
• 在实现中放入 NSLog 或其他诊断代码

例如，这将在每次按下 UIButton 时打印一条日志:

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)
}
