I got an IBAction and a CALayer (in the viewDidLoad) so what I need is to add a CALayer (in diffrent CGPoints) when the user click the add button.

I think you are a newbie in iOS, that's why I'm answering the answer, else I'll suggest to use google.

You can do it like:

- (IBAction)myButtonClick:(id)sender
{
    static float xPos = 0;
    static float yPos = 0;

    CALayer *myLayer = [CALayer layer];
    [myLayer setBounds:CGRectMake(0.0f, 0.0f, 50.0f, 30.0f)];
    [myLayer setPosition:CGPointMake(xPos, yPos)];   //You need to change the value here dynamically for changing the layer position
    [myLayer setFontSize:20];
    [self.view.layer addSublayer:myLayer];

    xPos += 50;
    yPos += 50;
}
