Question

I have an array of strings. The array was created by parsing a long comma delimited string into several component strings. I can NSLog those components and they appear correctly. However if I test one of those components for the very object the NSLog shows it as containing, the test still fails:

NSArray*parseLine=[[NSArray alloc] initWithArray:[newline componentsSeparatedByString:@","]];

NSLog(@"*%@*"[parseLine objectAtIndex:1]);

Output:

*N/A*

So clearly “N/A” is there, those three characters exactly.

However, this fails the test:

if ([parseLine objectAtIndex:1]==@"N/A") //never passes

Also tried this:

if ((NSString*)[parseLine objectAtIndex:1]==@"N/A")

Why doesn’t it pass the test?

Answer 1

== refers to address pointer as well as string.

To check for equality try isEqualToString function

So that will be

if([parseLine objectAtIndex:1] isEqualToString:@"N/A"])
