Question

I have an array of names but can’t seem to make the comparison work. Do I have an improper use of the language here?

NSLog(@"%@",[arrayOfNames objectAtIndex:0]);

if ([arrayOfNames objectAtIndex:0] == "Blue"){ 
  NSLog(@"it's Blue");
}
else {
  NSLog(@"it's not Blue");
}

The output is the following one:

Blue

it’s not Blue

Answer 1

Use the following:

if ([[arrayOfNames objectAtIndex:0] isEqualToString:@"Blue"])

You’re comparing two objects (one of the id-type, the other is a C-string) with the == operator. The comparison will fail, since they are 2 different objects. With the isEqualToString you are comparing the value of the object to the string @"Blue".
