How do I compare 2 integers without getting warnings?

I have a variable Player1Visits which is declared as int.

If I try to compare this to 1 using Player1Visits == 1 I get the warning comparison between integer and pointer. Should I be using a different type?

You haven't declared it as int, the compiler warning gives that away. Perhaps you've declared it as NSInteger *Player1Visits; or int *Player1Visits;.

If you declared it that way, remove the *.

I would double-check what Player1Visits is declared as; if you're getting that compiler warning, it is almost certainly not an int. Likely possibilities include what @aronchick said, where Player1Visits is an int* (a pointer to an int), so you want to compare using:

*Player1Visits == 1

Another possibility is that Player1Visits is some kind of object with an int property, where you want to figure out what property name you want and call:

[Player1Visits someIntProperty] == 1

(This last assumes you're using Objective-C, which is (I believe) a not-unreasonable assumption given your choice of IDE.)

Don't you mean to compare:

*Player1Visits == 1
