Answer 1

override hitTest:withEvent method

signature

- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event

Above method is supplied with CGPoint which is the location of touch.Create a CGPoint class property and store the touch-location in it.

@property (nonatomic,assign) CGPoint previousTouch;

- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event{
   self.previousTouch = point;
   return [super hitTest:point withEvent:event];
}
