See CGRectContainsPoint() in the documentation.

bool CGRectContainsPoint(CGRect rect, CGPoint point);


  • rect The rectangle to examine.
  • point The point to examine. Return Value true if the rectangle is not null or empty and the point is located within the rectangle; otherwise, false.

A point is considered inside the rectangle if its coordinates lie inside the rectangle or on the minimum X or minimum Y edge.
