跟蹤iOS應用程序的任何用戶交互

Question

如何跟蹤或捕獲iOS應用程序的每個用戶交互？ 就像按下一個UIButton，UIBarButton，...任何UIControl元素一樣。

我知道有數百種分析工具，例如Google Analytics（分析），Flurry，Appsee等，但我想將這些數據保存在自己的服務器上。

Answer 1

您好@tuvok，如果您不想使用Google Analytics（分析）和其他庫，則必須制作一個API（Web服務）。 您必須在每次用戶互動（例如按下按鈕或其他操作）時都點擊api。

Answer 2

您可以將UIApplication子類化：

• 創建一個UIApplication子類
• 覆蓋sendAction（_ action：Selector，以target：Any ?，從sender：Any ?，對於event：UIEvent？）事件方法，請記住調用超級實現
• 將NSLog或其他診斷代碼放入實現中

例如，這將在每次按下UIButton時打印一條日志：

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)
}

找到了一個簡單的解決方案：

1。創建一個UIControl擴展

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")
    }
}

2. 在AppDelegate中初始化：

   @UIApplicationMain類AppDelegate：UIResponder，UIApplicationDelegate {

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