I was able to write a UIAlertController for my button, and it work fine, but I don't know how to segue to a different page once I press the YES or OK button. At the moment, the YES or OK button goes nowhere.
@IBAction func SubmitButton(sender: AnyObject) {
if a > 28.87 {
var alert = UIAlertController(title: "H4 with Guide Pins", message: "Can it be removed?", preferredStyle: UIAlertControllerStyle.Alert)
alert.addAction(UIAlertAction(title: "YES", style: UIAlertActionStyle.Default, handler: nil))
alert.addAction(UIAlertAction(title: "NO", style: UIAlertActionStyle.Default, handler: nil))
self.presentViewController(alert, animated: true, completion: nil)
}
else if data2.text == "" {
var alert = UIAlertController(title: "Dimension", message: "Missing Data Input.", preferredStyle: UIAlertControllerStyle.Alert)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil))
self.presentViewController(alert, animated: true, completion: nil)
}
else {
var alert = UIAlertController(title: "H4 with Guide Pins", message: "Enter Swallow Dimension.", preferredStyle: UIAlertControllerStyle.Alert)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil))
self.presentViewController(alert, animated: true, completion: nil)
self.view.endEditing(true)
}
}
You could create a segue in your storyboard, control dragging from the yellow view controller at the top of a scene to a new view controller. Then give that segue an identifier in the inspector. You can call that from the handler in your code.
alert.addAction(UIAlertAction(title:"OK", style: .Default, handler: { action in self.performSegueWithIdentifier("mySegueIdentifier", sender: self) }
