Where to place ||

I know that this is a really simple question, but where should I place the || below if I want to check for both CAF and AAC? Thanks!

if ([[file pathExtension] isEqualToString:@"caf"])

|| means 'or' in Objective c. So this if (a == 1 || a == 2) means if a is equal to 1 OR a is equal to 2. So:

== equal

&& and

|| or

if ([[file pathExtension] isEqualToString:@"caf"] ||
    [[file pathExtension] isEqualToString:@"aac"] )

Note - this is a literal comparison so it is not case insensitive - if you want to do a case insensitive comparison:

if ([[file pathExtension] compare:@"caf" options:NSCaseInsensitiveSearch] == NSOrderedSame || 
    [[file pathExtension] compare:@"aac" options:NSCaseInsensitiveSearch] == NSOrderedSame)

You have to test it twice:

if ([[file pathExtension] isEqualToString:@"caf"] ||
    [[file pathExtension] isEqualToString:@"aac"])

Or, avoid some repetition by doing it like:

NSString *ext = [file pathExtension];
if ([ext isEqualToString:@"caf"] ||
    [ext isEqualToString:@"aac"])
