Question

I have a NSString(e.g. ‘P1’)
I have to add 1 in this NSString to get ‘P2’.
How will i do this??
Thanks for any help.

You can convert your NSString to an NSInteger like so:

NSInteger myInteger = [[myString substringWithRange:NSMakeRange(1, 1)] integerValue];

In your case if myString was your string P1, myInteger would be 1. So you could then do:

myInteger = myInteger + 1;

Which would then make myInteger 2. To then put that number back after P do:

myString = [NSString stringWithFormat:@"P%i", myInteger];

Now myString is P2.
