nsstring - How to convert from int to string in objective c: example code

Question

I am trying to convert from an int to a string but I am having trouble. I followed the execution through the debugger and the string 'myT' gets the value of 'sum' but the 'if' statement does not work correctly if the 'sum' is 10,11,12. Should I not be using a primitive int type to store the number? Also, both methods I tried (see commented-out code) fail to follow the true path of the 'if' statement. Thanks!

int x = [my1 intValue]; 
    int y = [my2 intValue]; 
    int sum = x+y;
    //myT = [NSString stringWithFormat:@"%d", sum];
    myT = [[NSNumber numberWithInt:sum] stringValue];

    if(myT==@"10" || myT==@"11" || myT==@"12")
        action = @"numGreaterThanNine";

If you just need an int to a string as you suggest, I've found the easiest way is to do as below:

[NSString stringWithFormat:@"%d",numberYouAreTryingToConvert]
