Kuidas erineb punktmõju määramise meetod ja mõjuproov interfeisside arendamise kontekstis?

In interface development, especially on iOS, "hit testing" is the process by which the system determines which interface element is under the user's touch point.

Hit test is a check to see if a specific point (e.g., touch coordinates) falls within the bounds of an element.

Differences:

• Hit detection is a general process for finding the appropriate element to handle the touch event, which may include recursive searching through the view hierarchy.
• Hit test is a specific check for a single element, usually using the point(inside:with:) method, which returns true or false.

Thus, the system first tests hit detection for each element, then determines which element should receive the event.
