UIPopoverController changing the location of a UIPopoverArrowDirection

I want to move the UIPopoverArrowDirection to the left so that the actual arrow is no longer centered, but more than 25% on the left and 75% on the right.

To understand what I mean, to see two screenshots, I want it to look like the second ...

Normal popover

The Popover with correctly placed arrow that I want

The problem is that there is no real way to dig into the popover class ... If someone has not made a third party that I can use?

In any case, if anyone knows how to solve this problem, it seems to be a trivial problem ... please let me know ...

Check below the method in which you can specify the direction for the direction of the arrow.

- (void)presentPopoverFromRect:(CGRect)rect inView:(UIView *)view permittedArrowDirections:(UIPopoverArrowDirection)arrowDirections animated:(BOOL)animated
