Getting the coordinates from the location I touch the touchscreen
In a UIResponder
subclass, such as UIView
:
override func touchesBegan(touches: NSSet, withEvent event: UIEvent) { let touch = touches.anyObject()! as UITouch let location = touch.locationInView(self)}
This will return a CGPoint
in view coordinates.
Updated with Swift 3 syntax
override func touchesBegan(touches: NSSet, withEvent event: UIEvent) { let touch = touches.first! let location = touch.location(in: self)}
Updated with Swift 4 syntax
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { let touch = touches.first! let location = touch.location(in: self.view)}
Taking this forward for Swift 3 - I'm using:
override 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) }}
Happy to hear any clearer or more elegant ways to produce the same result
This is work in Swift 2.0
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) { if let touch = touches.first { let position :CGPoint = touch.locationInView(view) print(position.x) print(position.y) }}
