Hope this idea will help you.

  • Get X / Y Axis on touch event.

  • Pass X / Y axis information to some function which draw dynamic UItextField

    func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?)
{

    if let touch = touches.first {
        let position = touch.location(in: self)
        print(position.x)
        print(position.y)
    }
}



func addDynamicTextField(xAxis: CGFloat, yAxis: CGFloat)
{
    let someFrame = CGRect(x: xAxis, y: yAxis, width: 100.0, height: 30.0)

    let text = UITextField(frame: someFrame)

    imageView.addSubview(text)
}

  • Thank you for this good idea But I want resizing, change rotate and change text options by touching. – Abdullah Kanza Oct 24 '16 at 11:18

Check my detailed example here:

How to add interactive UILabels on top of a UIImageView?

The code there add two CALayers that detects taps and changes text. Using the same type of logic, you can add pan/pinch/rotate handlers that will handle move/resize/rotate.

After you wire up the handlers like in that sample, here's the remaining functions:

func moveLayer(_ recognizer:UIPanGestureRecognizer) {
    let p = recognizer.location(in: self)
    if layer1.editMode {
        layer1.position = p
    }
    if layer2.editMode {
        layer2.position = p
    }
}

func rotateLayer(_ recognizer:UIRotationGestureRecognizer) {
    let p = recognizer.location(in: self)
    if layer1.editMode {
        layer1.anchorPoint = CGPoint(x: 0.5, y: 0.5)
        layer1.transform = CATransform3DRotate(myRedEye.transform, recognizer.rotation, 0.0, 0.0, 1.0);        }
    if layer2.editMode {
        layer2.position = p
    }
}

func resizeLayer(_ recognizer:UIPinchGestureRecognizer) {
    _ = recognizer.location(in: self)
    if layer1.editMode {
        layer1.transform = CATransform3DScale(myRedEye.transform, recognizer.scale, recognizer.scale, recognizer.scale)
        recognizer.scale = 1
    }
    if layer2.editMode {
        layer2.transform = CGAffineTransformScale(myGreenEye.transform, recognizer.scale, recognizer.scale)
    }
}

This was code I wrote a year ago and never put in production. If my memory is good, the trickiest part was how iOS differentiates between a pinch and rotate gesture. Since both use two fingers, combining resizing and rotating led to some small unexpected (IMHO) behaviors.
