Question

如何跟踪或捕捉iOS应用的每个用户互动？就像按下UIButton，UIBarButton，......任何UIControl元素一样。

我知道有数百种分析工具，例如Google Analytics，Flurry，Appsee等，但我想将这些数据保存在自己的服务器上。

Answer 1

Hello @tuvok如果您不想使用Google分析和其他库，那么您必须制作API（Web服务）。你必须在按下按钮或其他任何用户互动时点击api。

Answer 2

您可以继承UIApplication：

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

例如，每次按下UIButton时都会打印一条日志：

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)
}

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")
    }
}

初始化：

@UIApplicationMain class AppDelegate：UIResponder，UIApplicationDelegate {
```
override init() {
    super.init()
    UIControl.classInit
}
```
