How to programmatically dismiss UIAlertController without any buttons?

Question

I\'m presenting an UIAlertViewController without any buttons, as it is supposed to just inform users that uploading is in progress. The app is supposed to upload some files

Answer 1

Generally the parent view controller is responsible for dismissing the modally presented view controller (your popup). In Objective-C you would do something like this in the parent view controller:

[self dismissViewControllerAnimated:YES completion:nil];

The same code in Swift versions < 3 would be:

self.dismissViewControllerAnimated(true, completion: nil)

Swift 3.0:

self.dismiss(animated: true, completion: nil)
