Adjust UIActivityIndicatorView position in AlertView - Swift

Question

I've been trying to adjust the position of IndicatorView inside UIAlertView, but it never works. i tried to set for loadingIndicator loadingIndicator.center = CGPointMake(alert.bounds.size.width / 2, alert.bounds.size.height - 50) but it didn't apply at all, take a look on this photo :

alert = UIAlertView(title: "Loading...", message: nil , delegate: nil, cancelButtonTitle: nil)
        loadingIndicator = UIActivityIndicatorView(frame: CGRectMake(50, 10, 37, 37))
        loadingIndicator.center = self.view.center
        loadingIndicator.hidesWhenStopped = true
        loadingIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.Gray
        loadingIndicator.startAnimating();

        alert.setValue(loadingIndicator, forKey: "accessoryView")
        loadingIndicator.startAnimating()
        alert.show();

Answer 1

Try following code:

        var alert : UIAlertView = UIAlertView(title: "Loading...", message: nil , delegate: nil, cancelButtonTitle: nil)
        var viewBack:UIView = UIView(frame: CGRectMake(83,0,100,100))

        var loadingIndicator: UIActivityIndicatorView = UIActivityIndicatorView(frame: CGRectMake(50, 10, 37, 37))
        loadingIndicator.center = viewBack.center
        loadingIndicator.hidesWhenStopped = true
        loadingIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.Gray
        loadingIndicator.startAnimating();
        viewBack.addSubview(loadingIndicator)
        viewBack.center = self.view.center
        alert.setValue(viewBack, forKey: "accessoryView")
        loadingIndicator.startAnimating()
        alert.show();
