Track any user interaction of an iOS App

Question

How can I track or catch every user interaction of my iOS app? Like pressing an UIButton, UIBarButton, ... any UIControl element.

I know there are hundreds of analytics tools like Google Analytics, Flurry, Appsee and so on, but I want to save these data on my own server.

You can subclass UIApplication:

• Create an UIApplication Subclass
• override the sendAction(_ action: Selector, to target: Any?, from sender: Any?, for event: UIEvent?) event method, remember to call the super implementation
• put an NSLog or other diagnostic code inside the implementation

Example, this will print a log every time an UIButton is pressed:

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)
}
