I am new to iOS, I am using UIPanGestureRecognizer
in my project. In which I have a requirement to get current touch point and previous touch point when I am dragging the view. I am struggling to get these two points.
If I use touchesBegan
method Instead of using UIPanGestureRecognizer
, I could get these two points by the following code:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
CGPoint touchPoint = [[touches anyObject] locationInView:self];
CGPoint previous=[[touches anyObject]previousLocationInView:self];
}
I need to get these two points in UIPanGestureRecognizer
event fire method. How can I achieve this? please guide me.
You can use this:
CGPoint currentlocation = [recognizer locationInView:self.view];
Store previous location by setting current location if not found and adding current location everytime.
previousLocation = [recognizer locationInView:self.view];
