objective c - comparison of two strings fails

Question

I make a comparison of two strings which are obviously identical. Unfortunately my if clause doesn′t work as expected:

NSLog(@"%@ == %@ ?",strippedString1,strippedString2);

if (strippedString1 == strippedString2) {
    [_newBuild setTextColor: [NSColor greenColor] ]; 
    [_OldBuild setTextColor: [NSColor greenColor] ]; 
}

This is my NSLog output: Build: 2A12-046 == Build: 2A12

Even a byte by byte comparison says both strings are identical:

Any clues ?

With == you are comparing pointer address, to compare the contents of the strings you could use:

 [strippedString1 isEqualToString: strippedString2];
