CGPoint of tap on UITableViewCell using touchesBegan - ios

Question

I am needing the CGPoint of a tap on my UITableViewCell. To do this I want to use the touchesBegan:withEvent: method in my subclassed UITableViewCell.
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
[super touchesBegan:touches withEvent:event];
UITouch *touch = [[event allTouches] anyObject];
CGPoint location = [touch locationInView:touch.view];
NSLog(#"%#", NSStringFromCGPoint(location));
}
How can I forward that from my UITableViewCell subclass to my current viewController so that I can make an action depending on where in the cell they tapped?
** I don't want to use a Gesture Recognizer on the cell since it will not allow the didSelectRowAtIndexPath: method to be called.

Either delegation or block call back would do it. Below is an example of using blocks
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
{
CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell" forIndexPath:indexPath];
__weak __typeof(self) weakSelf = self;
cell.touchedAtPoint = ^(UITableViewCell *cell, CGPoint point) {
[weakSelf doSomethingWithPoint:point);
};
return cell;
}
In the cell
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event;
{
[super touchesBegan:touches withEvent:event];
UITouch *touch = [[event allTouches] anyObject];
CGPoint location = [touch locationInView:touch.view];
void (^touchedAtPoint)(UITableViewCell *, CGPoint) = self.touchedAtPoint;
if (touchedAtPoint) {
touchedAtPoint(self, location);
}
}
- (void)prepareForReuse;
{
[super prepareForReuse];
self.touchedAtPoint = nil;
}
Declaration of ivar
#property (nonatomic, copy) void (^touchedAtPoint)(UITableViewCell *cell, CGPoint point);
