Trigger function in VC when modal view is dismissed
Swift 3
In your main VC viewDidLoad
add:
NotificationCenter.default.addObserver(self, selector: #selector(mainVc.functionName), name:"NotificationID", object: nil)
and add a function in main VC
func functionName() {
// Do stuff
}
in FirstStartVC call the method with
NotificationCenter.default.postNotificationName("NotificationID", object: nil)
Hope this helps!
A simple edit on Swift 4
NotificationCenter.default.addObserver(self, selector: #selector(self.funcName), name: NSNotification.Name(rawValue: "NotificationID"), object: nil)
Put @objc
before the function definition.
@objc func functionName() {
// Do stuff
}
In your code, you have:
func saveNewUser(){
self.delegation?.newUserAction()
self.dismiss(animated: true, completion: nil)
}
}
Simply write the code you want to run after dismissing in completion:
:
func saveNewUser() {
self.delegation?.newUserAction()
self.dismiss(animated: true, completion: { finished in
// on completion
})
}
}
(You might not even need to say finished in
or anything like that.)
