Draggable UITextView - ios

Question

I need to create a draggable UITextView.
I managed to create a draggable view and I tried to add a TextView as a subview but it didn't work, the TextView wasn't editable and it didn't appear inside the view but below it.
This is the custom view code I created:
class DraggableView: UIView {
var lastLocation:CGPoint = CGPointMake(0, 0)
override init(frame: CGRect) {
super.init(frame: frame)
// Initialization code
var panRecognizer = UIPanGestureRecognizer(target:self, action:"detectPan:")
self.gestureRecognizers = [panRecognizer]
self.backgroundColor = UIColor.redColor()
//add UITextView
var text = UITextView()
text.backgroundColor = UIColor.brownColor()
text.text = "This is a test"
text.frame = CGRectMake(self.center.x, self.center.y, 40, 40)
self.addSubview(text)
}
required init(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func detectPan(recognizer:UIPanGestureRecognizer) {
var translation = recognizer.translationInView(self.superview!)
self.center = CGPointMake(lastLocation.x + translation.x, lastLocation.y + translation.y)
}
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
// Promote the touched view
//self.superview?.bringSubviewToFront(self)
// Remember original location
lastLocation = self.center
}
}
How can I correctly add a TextView to a draggable view?

Answer 1

Try this code , I updated your detectPan method, may u need to adjust as per your requirement
class DraggableView: UIView {
var lastLocation:CGPoint = CGPointMake(0, 0)
var startFrame:CGRect!
override init(frame: CGRect) {
super.init(frame: frame)
// Initialization code
var panRecognizer = UIPanGestureRecognizer(target:self, action:"detectPan:")
self.gestureRecognizers = [panRecognizer]
self.backgroundColor = UIColor.redColor()
//add UITextView
var text = UITextView()
text.backgroundColor = UIColor.brownColor()
text.text = "This is a test"
text.frame = CGRectMake(self.center.x, self.center.y, 40, 40)
self.addSubview(text)
}
required init(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func detectPan(gesture:UIPanGestureRecognizer) {
switch(gesture.state)
{
case .Began:
self.startFrame = gesture.view?.frame
case .Changed:
let newCoord = gesture.locationInView(gesture.view)
let dX = newCoord.x
let dY = newCoord.y
let center = CGPointMake((gesture.view?.frame.origin.x)! + dX, (gesture.view?.frame.origin.y)! + dY)
gesture.view?.center = center
case .Ended:
gesture.view?.frame = self.startFrame
print("ended")
default:
print("will not handel")
}
}
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
// Promote the touched view
//self.superview?.bringSubviewToFront(self)
// Remember original location
lastLocation = self.center
}
}
