How to add a TextField to UIAlertView in Swift

Question

I have this code, but I dont know how to show a textfield inside the UIAlertView.

var altMessage = UIAlertController(title: "Warning", message: "This is Alert Message", preferredStyle: UIAlertControllerStyle.Alert) altMessage.addAction(UIAlertAction(title: "Done", style: UIAlertActionStyle.Default, handler: nil)) self.presentViewController(altMessage, animated: true, completion: nil) 

I have this code for textfield , how can I show this in UIAlerView

var my:UITextField = UITextField(frame: CGRectMake(0, 0, 10, 10))

I also tried this code:

var alert = UIAlertView() alert.title = "Enter Input" alert.addButtonWithTitle("Done") alert.alertViewStyle = UIAlertViewStyle.PlainTextInput alert.addButtonWithTitle("Cancel") alert.show() 

When I specify the AlertStyle plainText, it shows a TextField with default placeholder, "Login".. I want to change that, I want to show a Keyboard of Decimal Pad. I also want to handle the value the user enters into the textField. Can someone help me with this?

Answer 1

You can access the textfield with:

let textField = alert.textFieldAtIndex(0) 

Then to change the placeholder text:

textField.placeholder = "Foo!" 

And the keyboard type:

textField.keyboardType = ...
