How can I increase the y of a label, in swift? - swift

Question

So I am very new in Swift and I can't figure out how to increase the y value from a label.
I am trying to show in a label, some messages that a user types in an input... like a chat view.
So I have this code, but it puts all the messages one above the other:
I know that it is very messy, I am sorry for that.
Thanks!
//my label
#IBOutlet weak var label: UILabel!
//my text field
#IBOutlet weak var textF: UITextField!
#IBAction func buttonPressed(sender: AnyObject) {
//create a variable(input) to store my text from the TextField
var input = textF.text
//put that text in the label
label.text = input
var label2 : UILabel = UILabel(frame: CGRectMake(20, 20, 200, 21))
var isSendMessage: Bool = true {
didSet {
if isSendMessage {
var input = textF.text
label.text = input
textF.text = " "
// self.view.label.origin.y += 10
} else {
var input = textF.text
label2.text = input
textF.text = " "
}
}
}
label2.center = CGPointMake(160, 284)
label2.textAlignment = NSTextAlignment.Center
self.view.addSubview(label2)
//empty text field
textF.text = " "
label2.center = CGPointMake(160, 284)
label2.textAlignment = NSTextAlignment.Center
label2.text = input
//add it to the view
self.view.addSubview(label2)
}

Answer 1

Try this
Don't update Y axis directly as if your Y value is greater than the screen height then label will go off the screen.
Try the following code.
// Taking height and width of the screen
var height = UIScreen.mainScreen().bounds.size.height;
var width = UIScreen.mainScreen().bounds.size.width;
var x = 164.0 // Fixed height of the label
if x < height
{
x += 20.0 // Incrementing height value
if (height - 20) >= x // Checking the difference between screen height and x, so it doesn't go beyond the screen.
{
label.frame = CGRectMake(20.0, x, 200.0, 21.0)
self.view.addSubview(label)
}
else
{
// Setting default height
label.frame = CGRectMake(20.0,164.0, 200.0, 21.0)
self.view.addSubview(label)
}
}
Hope this will be helpful.

In a quick answer to your question, if you are just looking to change the position on the y-axis you can use the property .y under .center
self.yourLabel.center.y = self.yourLabel.center.y + 10
