Question

What is the syntax for checking if strings are identical?

in Java it is:
string1.equals(string2);

but what is it in objective C?

You’ll need to use isEqualToString for the most accurate results. I’ve included a couple examples on how to use it.

NSString *aString = foo;
NSString *bString = bar;
if ([aString isEqualToString:bString]) {
    NSLog("Match");
}
else NSLog("No Match");
//No match.

NSString *aString = foo;
NSString *bString = bar;
if ([aString isEqualToString:@"foo"]) {
    NSLog("Double Foo!");
}
else NSLog("No Match");
//Double Foo!

NSString *aString = foo;
NSString *bString = bar;
if (![aString isEqualToString:bString]) {
    NSLog("No Match");
}
else NSLog("Match");
//No Match
