IOS: verify if a point is inside a rect

Is there a way to verify if a

CGPoint
is inside a specific
CGRect
.
At example: I'm dragging an
UIImageView
and I want to verify if its central point
CGPoint
is inside another
UIImageView
how can I do?

Answer

See CGRectContainsPoint() in the documentation.

bool CGRectContainsPoint(CGRect rect, CGPoint point);

Parameters

  • 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.
