Actions occurring while a button is pressed - swift - ios

Question

In my swift project I have a button and I want to print on a label how much time this button has been pressed.
How can I resolve this problem?

Answer 1

Adding to DHEERAJ's answer, you just need to add following code in func pressed(sender: UIButton!) to achieve what you need:
let date = NSDate()
let dateFormatter = NSDateFormatter()
dateFormatter.dateStyle = .MediumStyle
let dateString = dateFormatter.stringFromDate(date)
yourLabelName.text = dateString
Hope this might help.

To show how many times the button has been clicked you could class variable.
class SampleViewController: UIViewController {
var counter : Int!
#IBOutlet weak var yourLabelName: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
counter = 1
let myFirstButton = UIButton(frame: CGRectMake(10, 50, 320, 40))
myFirstButton.setTitle("Tap Me", forState: .Normal)
myFirstButton.setTitleColor(UIColor.blueColor(), forState: .Normal)
myFirstButton.addTarget(self, action: "pressed:",forControlEvents: .TouchUpInside)
self.view.addSubview(myFirstButton)
}
func pressed(sender: UIButton!)
{
yourLabelName.text = "Pressed : \(counter)"
counter = counter + 1
}
}

Here is how button is created programmatically and prints a text in label when button is pressed.
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let myFirstButton = UIButton()
myFirstButton.setTitle("Tap Me", forState: .Normal)
myFirstButton.setTitleColor(UIColor.blueColor(), forState: .Normal)
myFirstButton.frame = CGRectMake(10, 50, 320, 40)
myFirstButton.addTarget(self, action: "pressed:", forControlEvents: .TouchUpInside)
self.view.addSubview(myFirstButton)
}
func pressed(sender: UIButton!)
{
yourLabelName.text=#"Your Text is here"
}
