I am working on getting a simple calculator working as part of my adventure to learning Object-C and iOS development.

In Object-C using NSString, how does one look for a period in a string?

Based on the comments this is what I got so far.

NSString * tmp = [display text];

NSLog(@"%@", tmp); // Shows the number on the display correctly

int x = [tmp rangeOfString:@"."].location;

NSLog(@"%i", x); // Shows some random signed number 

if (x < 0) {
    [display setText:[[display text] stringByAppendingFormat:@"."]]; 
}

It is still not working :(
