NSIndexPath warnings in Obj-C

Question

I get a warning when creating NSIndexPath,

NSInteger arr[] = {0,3};
[NSIndexPath indexPathWithIndexes:arr length:2]

warning: pointer targets in passing argument 1 of 'indexPathWithIndexes:length:' differ in signedness

What is the warning due ?? How to make it work?

thank

Answer 1

You need to have an array of type NSUInteger(unsigned).

This tells you that since NSIndexPath does NOT want negative values ​​that you could potentially pass through an NSInteger array (really, int).
