I want to create a function that takes two different subclasses of UIViewController. One is a UITableViewController, and one is a UIViewController (both inherit from UIViewController). In my function, I want to then check which type the ViewControllers are, in order to access their properties in my function. How can I do this, if it is possible? I have tired the following:
internal func myFunction(var controller: UIViewController) {
if controller is MyController {
controller = controller as! MyController
}
// Get errors saying my MyController properties are not available. Type of UIViewController has no member.
}
If I understand you right, you would like to know which type is your parameter. If so, use this kind of method:
internal func myFunction(controller: UIViewController) {
if let menu = controller as? MenuController {
//menu is you MenuCOntroller
} else if let table = controller as? UITableViewController {
//table is your UITableViewController
}
}
