iOS String to Integer

So, you want to convert an NSString to NSInteger, eh?

The easiest way to go from NSString to NSInteger is by using the NSString:intValue method, like so:
NSString *theString = @"99";
NSInteger *intResult = [theString integerValue];

NSString *myString = [NSString stringWithFormat:@"%i", intResult];
