How to pass the tab bar drag event to underneath view about floatingpanel

[daskaliuk]

Value of type 'FloatingPanelController?' has no member 'panGestureRecognizer'

[scenee]

Here I would like to drag the view even if I drag the tab bar. In other words, I have to detect the tab bar drag event and pass it to the underneath view.

I'm sorry I can't imagine this use case... Could you please give me a screen capture video?

Thanks for the quick response!
Here is the use case

Thanks, @Thavasidurai. What's a problem in FloatngPanel library?

[Thavasidurai]

There is no issue in the library. I am just requesting help or raising a feature request to solve my use case.

Is there any provision to call something from parent view controller which moves up the FloatngPanel? If so, I can get the touch point from the tab bar and pass it to the FloatngPanel. I hope this would solve my problem.

If you know any other better approach to solve my use case, please guide me.

Thanks in advance!

I am getting expected output following an ugly way!

I just added a pan gesture to the tab bar and passed it to the floating panel's handle pan gesture method it's working perfectly but I need to modify the library code to change the access control to public from private. I know this is not the right approach, Is there any other way to handle it nicely or Is it possible to provide any other provision in the library to handle it without touching library code?

Sounds great. I'd like to consider a better approach. Could you let me know which method you changed?

Thanks again for your quick response! @scenee
I made all the required changes to access the @objc func handle(panGesture: UIPanGestureRecognizer) method from my view controller class so that I can pass whatever I receive from tab bar pan gesture handling method.

Below are my change logs

1. In FloatingPanelController.swift file, line number 128
   private var floatingPanel: FloatingPanel! to public var floatingPanel: FloatingPanel!

2. In FloatingPanel.swift file, line number 10
   class FloatingPanel: to public class FloatingPanel:

3. In FloatingPanel.swift file, line number 750
   override func responds(to aSelector: Selector!) to override public func responds(to aSelector: Selector!)

4. In FloatingPanel.swift file, line number 754
   override func forwardingTarget(for aSelector: Selector!) to override public func forwardingTarget(for aSelector: Selector!)

5. In FloatingPanel.swift file, line number 258
   @objc func handle(panGesture: UIPanGestureRecognizer) to @objc public func handle(panGesture: UIPanGestureRecognizer)

How about adding a target to FloatingPanleController.panGestureRecognizer?

    fpc.panGestureRecognizer.addTarget(self, action: #selector(handleFloatingPanel(panGesture:)))
    ...
}
@objc func handleFloatingPanel(panGesture: UIPanGestureRecognizer) {
    // Do something
}

I added panGestureRecognizer property in FloatingPanelController on v1.1.0 🙂
