objective c, NSMutableArray: indexOfObject

int k = 0;
k = [myArray  indexOfObject:_endNode];

I only have a few objects added to the array and _endNode isn't one of them.

I expect my k value to be -1. But, my k on the second line gives me a value of 21787887.

It's actually NSNotFound ans defined as NSIntegerMax

NSArray *array = [[NSArray arrayWithObject:_endNode] arrayByAddingObjectsFromArray:Myarray];
int k;
k=[array indexOfObject:_endNode];

This information may help you,

I think there is no DATA in you _endNode so its returning the junk value for the "k"

Please check the values of _endNode.....

It's actually NSNotFound, which is defined as NSIntegerMax.

This, by the way, is quite explicit in the documentation.
