AlertView button to specific ViewController - xcode

Question

I am looking at how to do an AlertView that when the button "OK" is pressed it takes you to a specific View Controller called DiveNumberViewController.
I have the AlertView code done (see below) but can't figure out how to have the OK button to the DiveNumberViewController. Any Help is appreciated.
I am using Xcode 6.3 and Swift
var Alert:UIAlertView = UIAlertView(title: "Alert", message: "Hello", delegate: self, cancelButtonTitle: "OK")
Alert.show()

Answer 1

Try this instead:
//// MARK - UIAlertViewDelegate
func alertView(alertView: UIAlertView, clickedButtonAtIndex buttonIndex: Int) {
//index of cancel button
if buttonIndex == 0
{
//add code if needed
}
//index of OK button
if buttonIndex == 1
{
//add code to go to your controller
var divenumberViewController = self.storyboard?.instantiateViewControllerWithIdentifier("DiveNumberViewController") as! DiveNumberViewController
self.navigationController?.pushViewController(divenumberViewController, animated: true)
}
}
Also, check your storyboard to be sure to have your controller class and your storyboard id setup inside.
Custom class | class : DiveNumberViewController
Identity | Storyboard ID : DiveNumberViewController

You can do like this :
var alert:UIAlertView = UIAlertView(title: "Alert", message: "Hello", delegate: self, cancelButtonTitle: "Cancel", otherButtonTitles:"OK")
alert.show()
Or
var alert:UIAlertView = UIAlertView(title: "Alert", message: "Hello", delegate: self, cancelButtonTitle: "Cancel")
alert.addButtonWithTitle("OK")
alert.show()
Don't forget to add the delegate
MyController : UIViewcontroller, UIAlertViewDelegate
When the user will click on the buttons, the delegate will fire this function below. So add your code here to go to DiveNumberViewController
//// MARK - UIAlertViewDelegate
func alertView(alertView: UIAlertView, clickedButtonAtIndex buttonIndex: Int) {
//index of cancel button
if buttonIndex == 0
{
//add code if needed
}
//index of OK button
if buttonIndex == 1
{
//add code to go to your controller
}
}
}
If you use a lot of UIAlertView in a same controller, you can add a tag to each UIAlertView like that. It will allow to add a specific action depending of the UIAlertView which is clicked
alertView.tag = 999
