Summary

• How to custom background touch event for SBULoading

Guide & Snippet

By default, background touch events for SBULoading are blocked.

This section describes how to customize touch events

1. Implement SBULoadingDataSource

First, implement the shouldPassTouchHit(_:with) of SBULoadingDataSource like the example below
The boolean in the return value indicates whether it passed.
If false, the touch is ignored; if true, the touch event is passed to the next view's event chaining.

extension GroupChannelViewController: SBULoadingDataSource {
    func shouldPassTouchHit(_ point: CGPoint, with event: UIEvent?) -> Bool {
        if self.navigationController?.navigationBar.frame.contains(point) == true {
            return true
        }
        return false
    }
}

2. Set & Remove SBULoadingDataSource

Touch event customization is designed to set the dataSource for each ViewController.
So when the ViewController is appeared or disappeared, call the dataSource setting method.
See the code below.

final class GroupChannelViewController: SBUGroupChannelViewController {
    
    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        
        SBULoading.setDataSource(dataSource: self)
        
    }
    
    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        SBULoading.removeDataSource()
    }
}
    

3. Setup SBUViewControllerSet

Finally, set the customized ViewController for SBULoading in the SBUControllerSet

class AppDelegate: UIResponder, UIApplicationDelegate {
    func application(
        _ application: UIApplication, 
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
        // ...
        SBUViewControllerSet.GroupChannelViewController = GroupChannelViewController.self
        return true
    }
}
