How do I recover the value of a button ?
For example:
I have a button in my layout with the name boot, but I want to assign the name of that button to be clicked on a variable!
That is possible?
Thank you

This will require checking the property sender.tag and use the button to identify which button is being fired.

It should also change the type Sender
AnyObjectforUIButton

Just you take the sender.titleLabel.text, how he is a UIButton there is no property value
How your Sender is AnyObject, you will need to cast him
let value = sender.titleLabel.text as! String
If using this button only method, I recommend changing from AnyObject for UIButton
Edit
You need to grab the button label (titleLabel) and then pick up the text (text) as the above example

Do not recommend! String. just add ! the text property
-
For what reason Leo? as his object is
AnyObjectownXCodewill force him to put it because he won’t recognize the property type -
The type of the text propriedate is String? Already Sender being Anyobject you must make the conditional cast Select? Uibutton
-
But in this case, using
as! Stringit is ensuring that it will always be text, in the context of its application that is true -
But the best is to change the Nder to Uibutton

I fully agree :)

You’re forcing unwrap as! String. Direct force . text!

You must access the property
sender.tag– Felipe Assunção
Then Sender.tag I have access to tag here what I did, I made an array with which I needed and when the tag matches the array I display =D Thanks!

Switch Sender: Anyobject to Uibutton and a print on Sender.currentTitle!
