Guide & Snippet

• When using a tabbar and it is configured as a custom rather than a tabbar in the UITabbarController, the internal function that calculates the height value of the tabbar internally in Sendbird UIKit may not calculate the value correctly.

• In this case, any ViewController class that inherits from SBUBaseViewController can override the functions that calculate the two height values below and modify them to the correct values.

  • getAdjustedKeyboardHeight(with:)
  • getTabBarHeight()

• The example below is based on SBUGroupChannelViewController, one of the many ViewControllers.

  • All subclasses of SBUBaseViewController can be customized in the following ways.

class CustomGroupChannelVC: SBUGroupChannelViewController {
    override func getAdjustedKeyboardHeight(with keyboardFrame: CGRect) -> CGFloat {
        // Implement logic to add or calculate height values
        let customHeight = 50.0
        return customHeight
    }
    
    override func getTabBarHeight() -> CGFloat {
        // Implement logic to add or calculate height values
        let customHeight = 50.0
        return customHeight
    }
}

• Before using the custom class, please set that in SBUViewControllerSet.

SBUViewControllerSet.GroupChannelViewController = CustomGroupChannelVC.self
