Question

I've created a mutable array containing NSRect values. I want to check whether the NSPoint I created is within this rectangle. What is the best way to do this in cocoa.

Was it helpful?

Solution

From the Foundation Functions Reference:

BOOL NSPointInRect (
   NSPoint aPoint,
   NSRect aRect
);

"Returns a Boolean value that indicates whether a given point is in a given rectangle."

OTHER TIPS

A valid question because not everyone realises that there are a great many helper functions provided in the Foundation NSRect Extensions Reference file which save you having to re-invent the wheel all over the place.

Have a quick read through the reference to see all the different places it can help. I found it very useful when starting out.

NSPointInRect?

I started this thread What Cocoa/Core Foundation helper functions do you wish you knew about 2 years ago? You may find something else you didn't know about.
