Question

I am trying to display an activity indicator when the user hits the login button. If I put the startActivityIndicator() code in viewDidLoad() it sh

Answer 1

Using my delay utility (see here: https://stackoverflow.com/a/24318861/341994), rewrite like this:

@IBAction func btnSignIn(sender: AnyObject) {
    startActivityIndicator()
    delay(0.1) {
        if validateEmailAddress(txtEmailAddress.text!) == false {
        // ... everything else goes here ...
    }
}

The delay gives the activity indicator a chance to appear and start spinning.
